Coasts

Question 1

Where are all the sub-aerial processes common?

Answer 1

Hydraulic action = ?

Cavitation = jointed, well-bedded rocks, eg limestone and poorly consolidated clays and glacial deposits

Abrasion = ?

Corrasion = ?

Solution = calcareous rocks like chalk and limestone

Attrition = ?

Frost shattering/freeze thaw = well-jointed sedimentary rocks eg limestones

Salt crystallisation = sedimentary rocks

Heating and cooling = ?

Carbonation = affect limestone cliffs eg Southern England

Hydrolysis = granite cliffs eg North Devon and Cornish coastlines

Oxidation = iron minerals - sandstones, siltstones, and shale often contain iron compounds

Hydration = Cliff face/wave cut platform
