Coastal erosion, transportation and deposition

Which key term goes with the definition 'The wearing away and removal of material by a moving force, such as a breaking wave. '

• deposition

• erosion

• transportation

Which key term goes with the definition 'The movement of eroded material.'

• erosion

• deposition

• transportation

Which key term goes with the definition 'material being transported by the sea is dropped due to the sea losing energy.'

• erosion

• deposition

• transportation

What type of erosion is this: The force of the water against the cliff can cause air to be trapped in cracks and crevices. The pressure weakens the cliff and gradually wears it away.

• abrasion

• attrition

• solution

• hydraulic action

What type of erosion is this: when rocks and boulders transported by waves bump into each other and break up into smaller pieces.

• abrasion

• attrition

• solution

• hydraulic action

What type of erosion is this: the wearing away of cliffs by sediment flung by breaking waves.

• abrasion

• attrition

• solution

• hydraulic action

What type of erosion is this: soluble particles are dissolved into the river.

• abrasion

• attrition

• solution

• hydraulic action

Which of these definitions defines the key term 'sliding' ?

• The decomposition (or rotting) of rock caused by a chemical change within that rock; sea water can cause chemical weathering of cliffs.

• Weathering processes that cause physical disintegration or break up of exposed rock without any change in the chemical composition of the rock, for instance freeze thaw.

• The downhill movement of weathered material under the force of gravity. The speed can vary considerably.

• Rapid mass movement which involves a whole segment of the cliff moving down-slope along a saturated shear-plane or line of weakness.

• Occurs after periods of heavy rain when loose surface material becomes saturated and the extra weight causes the material to become unstable and move rapidly downhill, sometimes in an almost fluid state.
