1.
The natural chemical or physical processes that breaks down rock on Earth's surface.
a)
weathering
b)
erosion
c)
deposition
d)
jackhammering
2.

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

a)

mechanical weathering

b)

chemical weathering

c)

sediment

d)

deposition

3.

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

a)

mechanical weathering

b)

chemical weathering

c)

sediment

d)

deposition

4.
These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:
a)
ice wedging
b)
chemical weathering
c)
acid rain
d)
abrasion
5.
These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:
a)
ice wedging
b)
acid rain
c)
permeability
d)
abrasion
6.

This rock has many spaces or holes which allow water to seep through it, meaning it...

a)

has more surface area available, so it may chemically weather easily.

b)

will weather more slowly due to the drafty effects of the holes.

c)

won't weather any differently from a more solid rock.

d)

will remain unchanged because the water can flow through.

7.
How is mechanical weathering different from chemical weathering?
a)
Chemical weathering happens over much shorter time frame than mechanical weathering.
b)
Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.
c)
Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.
d)
Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.
8.

Tree roots growing into the cracks in a sidewalk and the sidewalk cracking is an example of:

a)

mechanical weathering by root wedging

b)

chemical weathering by acidic rain water

a)

chemical weathering by by abrasion

b)

chemical weathering by oxidation

The formation of large cracks in the face of a mountain from repeated freezing and thawing of water in smaller cracks is an example of:

a)

mechanical weathering by ice wedging

b)

chemical weathering by hydrolysis

c)

mechanical weathering by abrasion

d)

mechanical weathering by crystal growth

15.

Lichens growing on a large boulder release enzymes and other acids that slowly break the rock apart. This is an example of:

a)

mechanical weathering by wedging

b)

chemical weathering by hydrolysis

c)

chemical weathering by dissolution

d)

chemical weathering by oxidation

16.
