a)
weathering
b)
erosion
c)
deposition
d)
jackhammering
2.
The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.
a)
weathering
b)
erosion
c)
deposition
d)
dumptruck
3.
This type of weathering occurs when rock is physically broken down into smaller pieces of rock.
a)
mechanical weathering
b)
chemical weathering
c)
erosion weathering
d)
deposition
4.
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)
erosion weathering
d)
deposition
5.
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
6.
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
7.
This rock may chemically weather easily because is has many spaces or holes in it that allow water to seep through it, meaning it is:
a)
permeable
b)
abrasive
c)
erosion
d)
unchangable
8.
These gravestones have slowly broken down and turned a blackish color due to the action of:
a)
ice wedging
b)
abrasion
c)
acid rain
d)
mechanical weathering
9.
How might a weathered mountain appear different than an unweathered mountain?
a)
Weathered mountain would be taller.
b)
Weathered mountain would be rounder and less jagged.
c)
Weathered mountain would be more jagged and less rounded.
d)
Weathered mountain would have no trees.
10.
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.
11.
Weeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:
a)
mechanical weathering
b)
chemical weathering
12.
Potholes forming in the road after a cold winter is an example of:
a)
mechanical weathering
b)
chemical weathering
13.
A metal statue slowly turning green after years of being outside is an example of:
a)
mechanical weathering
b)
chemical weathering
14.
Rocks along a riverbed that are smoothed from continuously moving water and sediment rubbing against them is an example of:
a)
mechanical weathering
b)
chemical weathering
15.
A piece of sandstone changing color (from brown to rusty red) from exposure to water and air is an example of:
a)
mechanical weathering
b)
chemical weathering
16.
The formation of stalactites and stalagmites in a cave as water mixed with carbon dioxide creates carbonic acid, which dissolves away the limestone, is an example of:
a)
mechanical weathering
b)
chemical weathering
17.
The formation of large cracks in the face of a mountain from ice wedging is an example of:
a)
mechanical weathering
b)
chemical weathering
18.
Acid rain wearing away the face of a marble gravestone or statue is an example of?
a)
mechanical weathering
b)
chemical weathering
19.
Exposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart. This is an example of:
a)
mechanical weathering
b)
chemical weathering
20.
Lichens (small green plants) growing on a large boulder release enzymes and other acids that slowly break the rock apart. This is an example of:
a)
mechanical weathering
b)
chemical weathering
21.
What is the process that picks up and moves weathered rocks?
a)
deposition
b)
landslide
c)
weathering
d)
erosion
