Constructive Waves
Constructive waves:
Are shorter than they are longer
Have a long wavelength
Have a small wave height
Have a low frequency
Have a greater swash than backwash
Deposition is
greater
Than erosion!…read more

Here's a taster:

Processes of Erosion
Hydraulic Action:
Waves crash against cliff face and compresses air into the cracks, putting pressure on
the rock in which the rock eventually cracks.
Abrasion:
De-structive waves hurl pebbles and other material at the cliff face which remove
small particles from the cliff.
Attrition:
Eroded particles in the water smash into each other and break into smaller fragments
and are smooth and rounded.
Corrosion:
Weak carbonic acid in the sea water dissolves rock such as chalk and limestone.…read more

Here's a taster:

Processes of Transportation
Traction:
Large boulders are pushed along the sea bed by the force of the water.
Saltation:
Pebble sized particles are bounced along the sea bed by the force of the water.
Suspension:
Small particles like silt and clay are carried along in the water column.
Solution:
Soluble materials dissolve in the water and are carried along by the sea.…read more

Here's a taster:

Coastal Weathering
Freeze-Thaw Weathering:
Occurs when temperatures alternate above and below 0°C , and water gets into a rock
with cracks e.g. Granite. When the water freezes the rock expands by 9% which
puts pressure on the rock. When the water thaws it contracts and the pressure on
the rock is released. Repeated freezing and thawing widens the crack and causes
the rock to break up.
Chemical Weathering:
When the coastline comes in contact with acid from the rain and salt from the
seawater it creates carbonic acid which then causes the rock to react with it results
in rocks breaking down.…read more

amazing resource which covers the whole unit pls do this for all the other units 

Mr A Gibson

WOW - a really, really good resource. It covers everything from processes to case studies around the world in over 30 slides which are easy to read and factual. I would recommend this on your mobile device for looking at regularly to give you a really good insight into this area of the specification.

Bethany

This was an incredible resource which covered all the information from the unit. It was so much easier to make a mind map from, rather than sifting through my own notes and my revision guide. Thank you for making this invaluable resource!
