chemical weathering in the mesosphere
physical weathering in the hydrosphere
5
The diagram shows a process called frost action or ice wedging. This is an example of:
weathering
metamorphism
deposition
cementing
6
What process has caused the layer of paint on this wall to chip away?
hydration
deposition
weathering
erosion
7
The diagram shows a process called frost wedging. Frost wedging is an example of
deposition
metamorphism
weathering
cementing
8
What would happen to this landscape feature if the climate became more humid?
more weathering and erosion, producing a more angular landscape feature
less weathering and erosion, producing a more angular landscape feature
less weathering and erosion, producing a more rounded landscape feature
more weathering and erosion, producing a more rounded landscape feature
9
Which rock weathers most rapidly when exposed to acid rain?
limestone
basalt
quartzite
granite
10
This wire netting has been installed to prevent loss of property or life resulting from
folding and faulting
crosscutting and downwarping
weathering and erosion
high winds and flooding
11
Which of the following can cause weathering of earth's surface?
glaciers
sedimentation
mountain building
revolution
12
Which property of the gneiss sample prevented it from weathering due to acid?
mineral composition
crystalline texture
density
cleavage
13
Which property of the gneiss sample prevented it from acid?
density
crystalline texture
cleavage
mineral composition
14
Which statement describes how rock characteristics affect rates of weathering?
Rockswith gapsandcracks weather more quickly thanrocks withsmooth surfaces.
Rockthat r burieddeep underground weather more quicklythan rocksat surface.
Rockswithout minerals weather morequickly thanrocksmadeup of many minerals.
Rocks with metamorphic rock weather more quickly than sedimentary rocks.
15
What has most likely caused the writing on this tombstone to disappear?
weathering from water and ice
weathering from chemicals
weathering from sand
weathering from wind
16
Weathering occurs when
different weather patterns create different climates
rain and sleet provide the soil with water for plants
rocks and soil break down from contact with the atmosphere
soil gets nutrients from long exposure to the Sun
17
The formation of rock fragments and soil is most likely the result of
convection cells
weathering
gravity
hazardous weather
18
The formation of a range of tall mountains with rounded tops would most likely be the result of which two processes?
crustal plate movement and erosion
erosion and deposition
volcanic eruptions and earthquakes
tidal activity and production of greenhouse gases
19
Which rock layer shows the greatest resistance to weathering and erosion?
D
A
C
B
20
Unsorted,angula,rough-surfaced cobbles & boulders are found at the base of a cliff. What likely transported these rocks?
running water
gravity
wind
ocean currents
21
As a quartz pebble is transported by a stream, the pebble will become more rounded as a result of
abrasion by colliding with other rocks
deposition in well-sorted layers
dissolving as water is running over the rock
resistance to weathering and erosion
22
Which process is likely responsible for the layers of rock that are missing in the center of the diagram?
deposition
uplift
collision
erosion
23
The picture seems to be smoothed and rounded. Which of the following is the most likely agent of erosion to causethis?
none of the above
water
wind
glaciers
24
Which table shows the most likely process and agent of erosion responsible for this rounded sediment?
process: sandblasting. agent: running water.
process: deposition. agent: wind.
process: abrasion. agent: wave action.
process: landslide. agent: mass movement.
25
The sedimentary rock layers are being weathered and eroded at different rates because the rock layers:
are made of different materials
are horizontal
contain different fossils
formed during different time periods
26
What do we call the process of breaking down and wearing away rock?
deposition
filtration
weathering
erosion
27

selenite gypsum
garnet
pyroxene
plagioclase feldspar
