Question 2

Provide 2 examples of BIOLOGICAL weathering

Answer 2

1) PLANTroot growth
2) ANIMAL borrows

Question 3

Explain how ACID RAIN is an example of BIOLOGICAL weathering

Answer 3

CARBON DIOXIDE in the air reacts with minerals in the rock

Question 4

What do LICHES do on a rock to break it down through BIOLOGICAL weathering

Answer 4

LICHES give off chemicals to break up the rock to take up the minerals inside a rock

Question 5

Explain (in short) how HUMAN activities effect weathering

Answer 5

1) Burning of fossil fuels and pollution
2) Open mining
3) Construction

Question 6

How does CONSTRUCTION (human activity) effect weathering

Answer 6

Dynamite is used to break up rock.
The rocks are exposed to elements (such as wind and water)

Question 7

How does OPEN MINING (human activity) affect weathering

Answer 7

The surface is exposed to water and wind.

The water and wind reacts with the rock that leads to chemical weathering.

Question 8

How does BURNING OF FOSSIL FUELS or POLLUTION (human activity) affect weathering

Answer 8

It makes the air more acid and causes ACID rain

Question 9

Give a short definition of WEATHERING

Answer 9

Breaking down of rocks

Question 10

Give a short definition of EROSION

Answer 10

TRANSPORTING of material that has been weathered by WATER, WIND and ICE

Question 11

Give a short definition of DEPOSITION

Answer 11

DEPOSITION (weather materials) is loaded off at a new place
