Question 1

What are the three main processes of erosion?

Answer 1

Erosion involves attrition, corrosion, and hydraulic action.

These processes describe how materials are worn away and transported by natural forces.

Question 2

Fill in the blank: The process of erosion that involves the physical wearing away of rocks is called _______.

Answer 2

[attrition]

Question 3

What is hydraulic action in the context of erosion?

Answer 3

Hydraulic action refers to the force of water against rock surfaces, causing erosion.

This process can create features such as caves and arches.

Question 4

True or False: Corrosion is a process that involves the chemical weathering of rocks.

Answer 4

True

Corrosion involves chemical reactions that dissolve minerals in rocks.

Question 5

What is the result of the interaction between constructive and destructive processes in geology?

Answer 5

These processes shape the landscape through their opposing effects.

Constructive processes build up landforms, while destructive processes wear them down.

Question 6

Fill in the blank: The action of waves cutting into the coastline is referred to as _______.

Answer 6

[erosional action]

Question 7

What features can be formed as a result of erosional processes?

Answer 7

Erosional processes can create features such as stumps, arches, and coves.

These features are often seen along coastlines where erosion is prominent.

Question 8

What does the term ‘backwash’ refer to in coastal processes?

Answer 8

Backwash is the movement of water back down the beach after a wave breaks.

This process can influence sediment transport and erosion.

Question 9

What is the significance of weathering in the erosion process?

Answer 9

Weathering breaks down rocks into smaller particles, making them more susceptible to erosion.

It is a critical first step in the erosion cycle.

Question 10

Fill in the blank: The geological term for the gradual wearing away of rocks is called _______.

Answer 10

[weathering]
