General Weathering Regents Practice
1. The diagram below represents a naturally occurring geologic process.
Which process is best illustrated by the diagram?
A) cementation
B) erosion
C) metamorphism
D) weathering
2. The diagram below shows the stump of a tree whose root grew into a small crack in bedrock and split the
rock apart.
The action of the root splitting the bedrock is an example of
A) chemical weathering
C) erosion
B) deposition
D) physical weathering
3. Which activity demonstrates chemical weathering?
A) freezing of water in the cracks of a sandstone
sidewalk
B) abrasion of a streambed by tumbling rocks
C) grinding of talc into a powder
D) dissolving of limestone by acid rain
6. The cross section below shows sedimentary rocks being
eroded by water at a waterfall.
4. In which climate would the chemical weathering of
limestone occur most rapidly?
A) cold and dry
C) warm and dry
B) cold and humid
D) warm and humid
5. Chemical weathering will occur most rapidly when rocks
are exposed to the
A)
B)
C)
D)
hydrosphere and lithosphere
mesosphere and thermosphere
hydrosphere and atmosphere
lithosphere and atmosphere
The sedimentary rock layers are being weathered and
eroded at different rates primarily because the rock layers
A)
B)
C)
D)
formed during different time periods
contain different fossils
have different compositions
are horizontal
7. Which factor has the greatest influence on the
weathering rate of Earth’s surface bedrock?
A) local air pressure
C) age of the bedrock
B) angle of insolation
D) regional climate
8. The diagram below shows granite bedrock with cracks.
Water has seeped into the cracks and frozen. The arrows
represent the directions in which the cracks have
widened due to weathering.
9. The diagram below shows a process called frost
wedging.
Frost wedging is an example of
Which statement best describes the physical weathering
shown by the diagram?
A) Enlargement of the cracks occurs because water
expands when it freezes.
B) This type of weathering occurs only in bedrock
composed of granite.
C) The cracks become wider because of chemical
reactions between water and the rock.
D) This type of weathering is common in regions of
primarily warm and humid climates.
A) weathering
C) metamorphism
B) cementing
D) deposition
10. The diagram below represents a sedimentary rock
outcrop.
Which rock layer is the most resistant to weathering?
A) 1
B) 2
C) 3
D) 4
