Coastal Processes

Question 1

Traction

Answer 1

LARGE particles like boulders are PUSHED along the SEA BED by THE FORVE OF THE WATER.

Question 2

Saltation

Answer 2

PEBBLE sized particles are BOUNCED along the sea/river bed by THE FORCE OF THE WATER

Question 3

Suspension

Answer 3

SMALL particles like SILT and CLAY are CARRIED along in the water

Question 4

Solution

Answer 4

SOLUBLE MATERIALS DISSOLVE in the water and are carried along.

Question 5

LSD

Answer 5

The movement of material driven to the coast by the waves.
The direction of the wind is the direction the swath carries the sediment and deposits it on the coastline. The backwash then carries it back out to the sea (usually at a right angle to the coast).

Question 6

Abrasion

Answer 6

When pebbles grind along a rock platform-eventually the rock becomes smooth

Question 7

Attrition

Answer 7

When rocks that the sea carries knock against each other. Become smaller and more rounded.

Question 8

Undercutting

Answer 8

Lines of weakness (joints or cracks in rocks/cliffs/headlands) become enlarges and develop small sea caves. This can often lead to the formation of stacks, or wave cut platforms.

Question 9

Deposition

Answer 9

The laying of sediment carried by wind, water or ice. It’s deposited due to lack of energy (no longer enough energy to carry continuously).

Question 10

Wave quarrying

Answer 10

When high energy waves hit the cliff face and have the power to remove large chunks of rock.

Question 11

Erosion

Answer 11

Geographical process in which earthen materials are worn away.

Question 12

Mass movement

Answer 12

Large amounts of soil and Rick debris moving down slopes due to the force of gravity.
