Crack Cave Arch Stack Stump

Purposeful: To find out how surf form the shoreline.The coast is definitely the title given to the area where the land satisfies the ocean/ocean. Coasts are formed by the sea and the activity of mounds. The procedures that take place are usually erosion, transport and deposit.The activity of wavesThe power of ocean is certainly one of the most significant factors of coastal change.

What is a cave, a crack/fault, an arch, a stack and a stump in geographical terms? This is homework and i was absent from the lesson when they were taught about these terms. I would greatly appreciate it if someone coulld give me a brief description of these things? Caves, arches, stacks and stumps would be found on a headland, where the rock is exposed to erosional processes that eventually break through it. Continuous erosion, over time, may lead to two back-to-back caves breaking through a headland to form an arch. Choose from 93 different sets of arches stacks stumps flashcards on Quizlet. A sea stump is a sea stack that has been further eroded. The crack then grows into. Cave arch stack stump wave cut platform types of erosion hydraulic action abrasion attrition corrasion bays and headlands. Features of coastal erosion ws.

Dunes are made by wind blowing over the surface of the ocean. As the breeze blows over the ocean, friction is usually made - making a get bigger in the drinking water.

The power of the wind causes drinking water contaminants to move inside the swell and this goes the wave forwards.The dimension and power of a wave is impacted by:. how lengthy the breeze has been blowing. the strength of the wind.

how much the wave has travelled (the get). Do you realize swash backwash? - Study the diagram above and watch the 12 2nd YouTube cut.

Add a 30 2nd diagram to your reserve to help you to remember.Building Destructive WavesThere are usually two forms of waves, helpful and harmful. Watch the two YouTube videos beneath and then research the blueprints next to them. After that Switch YOUR VOLUME Straight down and to become taken to an interactive source where you can look at both.

(deconstructive = destructive)Task 4 - Make records on damaging constructive waves and make a design diagram to display the differences between the two forms. Watch the cliff break movie in Cornwall, British, to the right. This occurs all the time around the globe - the ocean benefits!

It'beds not often caught on surveillance camera even though.This provides occurred as a outcome of a amount of erosional processes. We are going to learn about these next.ii. Finish the worksheet to the ideal by making use of the details in this area.Coastal Erosion (typés of erosion)Cóasts being at the boundary of the property and the sea are incredibly vulnerable to erosion. They are infected by the tremendous power of the sea and the weather conditions.

The main ways that the ocean erodes the coastline are:Hydraulic Stress: This will be when sea drinking water and surroundings get stuck in breaks. The raising pressure of the water and air result in the stones to break.Corrasion (scratching): Rocks been thrown into the cliffs by ocean and breaking up off pieces of the cliff.Deterioration (remedy): The small level of acidity of sea water causing pieces of the cliff to dissolve.Attrition: Stones, sand and stones being thrown into each other by the sea current and ocean.Job 6 - View the iGCSE movie hosted by somebody familiar (to the right). What kind of erosion can you notice proof of? Take a display screen chance of component of the video, plant and annotate with key features.Additional revision job - Change to page 32 - 33 of the OCR B Geography book (you possess a duplicate on your computer systems).

Make information under the using headings make sure you:Weathering in coastal areasa. Bulk Movement. Purposeful: To discover how erosion causes various coastal features.Bays and HeadIandsBays and headlands are formed in a really similar method to rapids (streams topic). They are usually created when you get alternate layers of tough and gentle rock. The ocean is able to erode the gentle rock and roll a lot quicker than the difficult rock making a gulf.

The harder rock and roll forms a headland.BayAn indented region of property normally found between two headlands. Bays are usually more sheltered so there is definitely less erosive strength, indicating you often find beaches in bays.HeadlandA item of land that stays out into the ocean. Dunes refract around headIands so they experience a great deal of erosion forming features like arches and stacks (observe below).Wave Cut Level and Wave Lower PlatformWave cut platforms are usually made in a identical methods to waterfalls and gorges (rivers topic). At high tide the strength of the sea assaults and erodes the bottom of the cliff.

Over period this erosion creates a influx cut notch (basically an eroded gap at the bottom level of the cIiff). As the wave cut level gets bigger, the excess weight of rock above the level gets higher. Ultimately the cliff can not really help its own weight and it collapses. The process then starts once again, with the érosion of the sea producing a new wave slice level. As the process proceeds the cliff starts to proceed backwards (getaway).

Because the cliff is definitely moving backwards a wave cut system (an area of bare stone) is certainly developed. Wave slice platforms are only noticeable at low wave. Caves, Arches, Stácks and StumpsCaves, archés, stacks ánd stumps are usually discovered on headlands, where influx refraction is usually causing erosion on three sides. The ocean always look for weaknesses in the headland (breaks and joints).

If they discover a crack or a joint they will start attacking it. Hydraulic pressure will be the primary type of erosion. Overtime the split may convert into a cave. Gradually the cave will obtain larger and reduce all the method through the headland, producing an árch. As the árch will get larger the weight of the arch roof gets as well great and it collapses, leaving a stack. The stack is usually after that eroded by the ocean and weathered from the air flow making a stump.Blowhole: Sometimes the sea may erode thróugh to the top of the headland (sticking with a large crack).

If this occurs a blowhole can be created.Watch the really excellent movie to the correct hand side. Who would have thought that we could use plasticine to show the process!! Anyone want attempting this out at home in their sandpit?Job 3 - Generate an annotated design using the blueprints, YouTube video clip and description above to explain how caves, archés, stacks stumps form. Don't neglect to include a blowhole too.IST Students - You will observe this in Sitges.

Objective: To discover out how surf move material many KM along the coastline.Longshore Float or LSD is an essential process on every seaside. It is definitely the procedure by which materials movements along the beach everyday.

If you painted a pebble shiny pink, left it and came back again one week later, the ocean would possess transferred it to a completely different part of the seaside.Invest 5 minutes watching Mister Rogers (a very good Location teacher from Portsmouth, UK) detailing how Longshore Float works.Job 4 - Design your very own diagram to display how LSD works centered on what Mister Rogers says and pulls. Annotate it with as much details as probable. Objective: To recognize and explain the formation of the functions deposited by the seaBeach: The seaside is the deposition of sand between the least expensive spring tides and the highest spring tides. Beaches can become produced out of sand, shingle and/or pebbles. Beaches obtain their materials from longshore float, constructive ocean, cliff erosion and lake discharge.

Seashores cane be separated into backshore, overseas and foreshore. The backshore is the area above the normal high wave level, the foreshore is usually the area in between normal higher and reduced tide and offshore is certainly the area below the regular low wave.Berm: The berm can be a ridge (longer thin mountain) that forms at the best of the beach.

It is certainly the highest area of the beach and is basically sand gathered on the strand line (sticks, litter, seaweed, étc. Deposited at higher tide).Intertidal area: The area of land between high tide and reduced tide.Follicle range: The material (seaweed, driftwood) that is definitely deposited by the sea at furthest point of the higher tide. Objective: To find out how and where fine sand dunes are formed.Job 1 - Making use of the movie and the embedded demonstration to the best and the diagram below, create an on the development and framework of sand sand hills.will help you (supply: simply because nicely as.You should consist of the using;. How fine sand dunes are usually formed.

Information on each óf the six areas of a sand dune program. A picture of each area. An illustration of human makes use of of a sand dune ecosystem - possibly using.Alternative Task (IST Students)to gain access to your sand sand hills worksheet. Complete all jobs set out making use of all info within.Thanks tó: http://www.susséx.ac.uk/géography/researchprojects/BAR/workshéets.html.

Purposeful: To find out where and how coral reefs type and the risks posed to them by individual activity.Starter: Get a Google 'reefview' tour around Batu Bolong (check out out on Search engines Maps if you've certainly not noticed of it just before!). If you've in no way been reef diving before, this can be what it appears like. Impressive or what!? Nevertheless, if that'h not sufficiently, to become used to some live life webcams of réefs over in thé Caribbean. 'Bonaire' will be particularly very clear!Coral reefs are large underwater structures made up of the skeletons of coral reefs, which are underwater invertebrate animals. The coral types that construct coral reefs reefs are usually identified as hermatypic or'hard' corals because they get calcium mineral carbonate from seawater to make a hard, long lasting exoskeleton that shields their smooth, sac-like bodies.​Each specific coral is usually known to as á polyp. New coral polyps live on the calcium mineral carbonate exoskeletons of their ancestors, adding their very own exoskeleton to the present coral construction.

As the centuries pass, the coral reef gradually grows, one small exoskeleton at a time, until they become massive functions of the submarine environment. resource: livescience.comTask - Using the worksheet abové and the proof plank below, comprehensive all tasks arranged out on the PDF bed sheet by hand. ​Job 1 - on the importance of Mangroves as a organic reference and furthermore as deluge safety and complete the following tasks.

Produce your own worksheet that consists of the image below. After that complete the adhering to questions using the write-up above and the second movie (above):1. What are mangroves and where perform they normally develop?2. Explain what 'the origins also react as buffers' imply in terms of defense from water damage and tsunami'beds3. What 'passing away rate comparison' can become made over their performance after the 2004 Oriental Tsunami?4. Put together what is usually being accomplished to resolve the problem caused by mangrove elimination.5.

How is usually the removal of mangroves also linked to coastal erosion?Task 2 - Watch the short video beneath and research the image below. Create records on additional values and risks that you notice on the video. Purposeful: To generate an RSA style video making use of a technique of your selection to show coastal procedures (erosional depositional).RSA video clips are those that are usually manipulated by speeding up, delaying down, time lapse and over dubbed with your voice.You might remember viewing some illustrations created by Season 11 college students at the World School of Toulouse and Priory School, Portsmouth to the right. These are usually good examples of sped up videos that are usually over dubbed with narrative displaying the adjustments to the stream features on the Water Garonne. They are brilliant ways of learning and keeping in mind geographical procedures.Your job will be to full an RSA style video that incorporates the following:1. Erosion of headlands (joints, split, cave, arch, stack, stump)2. Transportation - LSD3.

Deposit - Beaches and/ór spits.You cán perform a traditional RSA like the very first two video clips or something a little even more innovative like the video clip to the right with Plasticine. There is definitely another video above (Headland Erósion by Jasmine) thát is usually more iGCSE in design. Your initiatives will be shown to the rest of the entire world on YouTube and a winner chosen. Intent:   To find out how human beings try out to earn the fight with the sea and its erosive power.Starter: To explain what we learnt last training, view from 8-10 a few minutes on the coasts video clip to the ideal.

Then, view from 10 moments forward.You are usually going to be putting together a truth bed sheet on both tough and soft engineering strategies to stopping coastal erosion.Hard System may be described as: A method regarding the structure of substantial man-made constructions to control the coastline. e.h.

Sea walls and Stone ArmourSoft System may be defined as: A technique concerning the structure of even more environmentally helpful, less harmful and arguably more sustainable management options. e.g. Beach nutrition or managed retreatTask 1 - Put together your very own fact sheet that aims to show the different ways that coasts can become safeguarded from destructive mounds, how those defenses function and their pros and downsides. There is usually a help sheet below right.Component 1 - Hard engineering approaches - Time for Geography Movie (groynes, sea wall, gabions etc)Component 2 - Soft engineering approaches - Period for Location Video.

Crack Cave Arch Stack Stump

Contents.Area Old Harry Stones lies straight east of, about 1.5 miles (2.4 km) northeast of, and about 3 kilometers (4.8 km) sth of the large towns of. To the southerly are the chalk cliffs of, very much of which is definitely owned by the. The stones can be seen from the Dorset section of the.Fórmation The chalk óf Aged Harry Stones utilized to be component of a lengthy stretch of chalk bétween Purbeck and thé Department of Wight, but remained as a headIand after large parts of this seam were eroded aside.

As the headland experienced hydraulic activity (a process in which surroundings and water are pushed into small splits by the push of the sea, ensuing in enlarging cracks), very first caves, after that arches formed. The surfaces of the arches flattened after getting stressed by rainfall and wind flow, leaving disconnected stacks. One óf these stacks is recognized as Old Harry. Old Harry's Spouse has been another stack which had been eroded through rust and abrasion, until the underside was therefore weak the best fell aside, leaving behind a stump. Hydraulic actions is the main cause of erosion (pure force of the wave) that damaged the rock and triggered it to drop aside.Geology The of Ballard Lower are produced of chalk with some rings of, and were formed approximately 66 million years ago. The bands of stone have been recently steadily eroded over the centuries, some of the previous stacks having dropped (Aged Harry's primary wife dropped in 1509), while brand-new ones have been shaped by the breaching of thin isthmuses.

Across the water to the east on the Isle of Wight are usually usually visible. These are usually also component of the exact same chalk music group and only a several thousand years ago were linked to.To form the stacks, the ocean steadily eroded along the joints and home bedding aeroplanes where the softer chalk satisfies harder bedrock of the rock and roll formations to create a cave. This ultimately correct through to generate an arch. The arch consequently flattened to depart the stacks of Aged Harry and his spouse, No Guy's Land and the space of St Lucas' Jump. The large outcrop of rock at the finish of the cliffs can be often known to as 'No Guy's Land'.Aged Harry can be shaped by erosion processes, which will ultimately eliminate the stack, whilst brand-new stacks create. Some individuals wish to preserve the stones and guard them from the erosive procedures that shaped Old Harry. The, who possess the stacks in perpetuity, have encounter in searching after the coast, and have discovered that 'operating with natural processes is definitely the most sustainable technique'.

Story There are usually various tales about the náming of the rocks. One star states that the (typically known euphemistically as 'Outdated Harry') slept on the rocks. Another local legend says that the rocks were named after, the infamous Poole, whose boat hid behind the stones awaiting spending merchantmen.Yet another story has it that á ninth-céntury Viking raid had been thwarted by a storm and that oné of the drownéd, Earl Harold, has been transformed into a piIlar of chalk.
