costal erosion

Question 1

4 types of costal erosion

Answer 1

attrition= big rock falls in ocean
land based erosion= water running away from the land
abrasion= sand rocks and boulders against a coastline like sand paper
solution= like chemical solution

Question 2

attrition

Answer 2

• when a large piece of rock falls away the waves gradually wear it down into smaller rock particles and sand.

Question 3

solution

Answer 3

• when a chemical reaction between air, the salt in the sea water and the rock surface causes small particles of rock to disintegrate.

Question 4

abrasion

Answer 4

• when a wave breaks it throws sand, small rocks and sometimes large boulders against rocky coastlines to wear away the rock.

Question 5

land based erosion

Answer 5

water running from the land can also erode the costal environment
