- 1. Multiple Choice
Which geologic feature is caused primarily by chemical weathering?
large caves in limestone bedrock
a pattern of parallel cracks in a granite mountain
blocks of basalt at the base of a steep slope
the smooth, polished surface of a rock in a dry, sandy area
- 2. Multiple Choice
Which statement best describes the physical weathering shown in the diagram?
This type of weathering occurs only in bedrock composed of granite
Enlargement of the cracks occurs because water expands when it freezes
The cracks become wider because of chemical reactions between water and the rock
This type of weathering is common in regions of primarily warm and humid climates
- 3. Multiple Choice
Which activity demonstrates chemical weathering?
freezing of water in the cracks of a sandstone sidewalk
abrasion of a streambed by tumbling rocks
grinding of talc into a powder
dissolving of limestone by acid rain
- 4. Multiple Choice
Which statement best explains why the dates are more difficult to read on tombstone A than on tombstone B?
Tombstone A is composed of minerals less resistant to weathering than Tombstone B.
Tombstone A has undergone a longer period of weathering than Tombstone B.
Tombstone A experienced cooler temperatures than Tombstone B.
Tombstone A was exposed to less acid rain than Tombstone B.
- 5. Multiple Choice
Which type of rock was chemically weathered by acidic groundwater to produce the cave and its features?
silstone
basalt
quartzite
limestone
- 6. Multiple Choice
Which type of weathering was primarily responsible for the development of these caves?
physical weathering of sandstone
physical weathering of limestone
chemical weathering of sandstone
chemical weathering of limestone
- 7. Multiple Choice
This soil was formed primarily by
erosion of glaciers
erosion by running water
human action
weathering and biological activity
- 8. Multiple Choice
Which process of change is best represented by the sequence shown in the diagram?
deposition
metamorphism
weathering
condenstation
- 9. Multiple Choice
What is the main difference between chemical and physical weathering?
Chemical weathering alters the composition of minerals, and physical weathering does not.
Chemical weathering increases the surface area of minerals, and physical weathering does not.
Physical weathering alters the composition of minerals, and chemical weathering does not.
Physical weathering increases the surface area of minerals, and chemical weathering does not.
- 10. Multiple Choice
Water is a major agent of chemical weathering because water
cools the surroundings when it evaporates
dissolves many of the minerals that make up rocks
has a density of about 1 g/mL
has the highest specific heat of all common earth materials
- 11. Multiple Choice
In which climate would the chemical weathering of limestone occur most rapidly?
cold and dry
cold and humid
warm and dry
warm and humid
- 12. Multiple Choice
Which climate has the greatest amount of rock weathering caused by freeze-thaw weathering?
A wet climate in which temperatures remain below freezing.
A wet climate in which temperatures alternate between below freezing and above freezing.
A dry climate in which temperatures remain below freezing.
A dry climate in which temperatures alternate between below freezing and above freezing.
- 13. Multiple Choice
What is the best example of physical weathering?
The cracking of rock caused by freezing and thawing of water.
The transportation of sediment in a stream.
The reaction of limestone with acid rainwater.
The formation of a sandbar along the side of a stream.
- 14. Multiple Choice
Weathering caused by wind is most common in regions that have
a hot climate
much loose sediment
weak bedrock
bedrock exposed to the atmosphere
- 15. Multiple Choice
In addition to its effects on living organisms, acid rain may cause changes in the landscape by
decreasing chemical weathering due to an increase in vegetation
decreasing physical weathering due to an increase in frost action
increase the breakdown of rock due to an increase in chemical weathering
increase physical weathering of rock material due to an increase in the circulation of groundwater
