The four processes of erosion are...? |
Hydraulic Action, Abrasion, Attrition and Solution |
Snowy Hippopotami Are Antique |
|
|
Hydraulic Action is... |
Where waves crash against rock and compress the air in the cracks. |
|
|
|
Abrasion is... |
Where eroded particles in the water scrape and rub against the rock |
Brace for impact! |
|
|
Attrition is... |
Where eroded particles smash into each other.
|
A War of Attrition.
|
|
|
Solution is... |
Where the weak carbolic acid in seawater dissolves rock. |
Chemical Solutions! |
|
|
The two types of Weathering are... |
Mechanical and Chemical Weathering |
Cogs and Acid |
|
|
Mass Movement is... |
The shifting of rocks and loose material down a slope. It is more likely to happen after it has rained |
Lots of movement? |
|
|
Wave cut platforms happen when... |
Waves undercut cliffs. The cliff is then too heavy to support itself, and collapses. This continues until the waves can't reach the cliff. The slope is a wave-cut platform! |
Undercutting... |
|
|
Headlands and Bays form when... |
Different types of rock are lined up against the sea. The softer rock is eroded quicker than the hard, so forms a bay and a headland.
|
Chalk and Clay
|
|
|
A cave is formed when... |
The natural cracks in the rock are exploited by Hydraulic Action and Abrasion |
Some caves can be really small... |
|
|
Arches are... |
Caves that have been completely eroded underneath, so just the top remains. |
Caves can have two ends. |
|
|
A Stack is formed when... |
An arch falls in, mainly due to weathering |
Isn't this acid rain nice? |
|
|
Stumps are... |
Collapsed Stacks. Simple. |
Wave-cut notches. |
|
|
Longshore drift is... |
The movement of sediment along the beach. It occurs when the prevailing wind is diagonal to the beach. |
Where longshores drift! |
|
|
The four processes of transportation are... |
Traction, Saltation, Suspension and Solution |
Many Ss, One T |
|
|
Traction is... |
Where large particles are pushed along the sea bed. |
Tractors pull heavy things. |
|
|
Saltation is... |
Where pebble-sized particles are bounced along the sea bed. |
Bouncy! |
|
|
Suspension is... |
Where small particles are carried along by the water. |
Suspense! |
|
|
Solution is... |
Where soluable materials dissolver in the water and are carried along. |
Like the erosional process |
|
|
Constructive wave characteristics include... |
Low height, low frequency, strong swash and weak backwash. |
The opposite of destructive waves. |
|
|
Destructive wave characteristics include... |
High height, high frequency, weak swash and strong backwash. |
The opposite of constructive waves. |
|
|
The fetch is... |
The area that the waves build up in - the place the wind blows over the water. |
Fetch me the wind! |
|
|
Beaches are formed by... |
Deposition! |
Not the other one. |
|
|
Spits are formed by... |
Longshore Drift pusing material out over and estuary. Then, wind direction changes suddenly, making a recurved end. Salt marshes build up in the tip. |
Not a bar. |
|
|
Bars are formed by... |
Longshore Drift pusihing material all the way over a bay, making a bar and a lagoon. |
Not a spit. |
|
|
What are the two main reasons that sea levels rise? |
- Melting of Ice in the Arctic - Thermal Expansion due to heating of the oceans Both of these are due to Global Warming |
Global Warming is heating up the world |
|
|
Rising Sea Levels will Increase Coastal Flooding. What is an Environmental Impact of Coastal Flooding? |
1) Ecosystems affected 2) Vegetation killed 3) Increased erosion |
It will destroy... |
|
|
Rising Sea Levels will Increase Coastal Flooding. What is an Economical Impact of Coastal Flooding? |
1) Loss of Tourism 2) Damage repair 3) Loss of agricultural land |
It won't be very attractive. |
|
|
Rising Sea Levels will Increase Coastal Flooding. What is a Social Impact of Coastal Flooding? |
1) Deaths 2) Water Supplies Contaminated 3) Loss of Housing 4) Loss of Jobs |
Lossing many thing. |
|
|
Rising Sea Levels will Increase Coastal Flooding. What is a Political Impact of Coastal Flooding? |
The goverment will have to make policies to reduce the impact - flood defences, better use of area etc. |
|
|
|
Sea Walls, Rock Armour and Groynes are all examples of what? |
Hard engineering! |
Guess... |
|
|
Beach Nourishment, Dune Regeneration, Marsh Creation and Managed Retreat are all examples of what? |
Soft engineering! |
