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. Which statement best describes the physical weathering shown by the diagram?
Enlargement of the cracks occurs because water expands when it freezes.
This type of weathering occurs only in bedrock composed of granite.
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.
The composition of residual soil is most likely determined by the
amount of average annual insolation
type of bedrock material
range of yearly temperature extremes
amount of potential evapotranspiration
Which property of water makes frost action a common and effective form of weathering?
Water dissolves many earth materials.
Water expands when it freezes.
Water cools the surroundings when it evaporates
Water loses 334 Joules of heat per gram when it freezes.
Which event is an example of chemical weathering?
rocks falling off the face of a steep cliff
feldspar in granite being crushed into clay-sized particles
water freezing in cracks in a roadside outcrop
acid rain reacting with limestone bedrock
Chemical weathering occurs most rapidly in climates which are
moist and warm
moist and cold
dry and cold
dry and warm
Which is the best example of physical weathering?
the cracking of rock caused by the 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
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
chemical weathering
deposition
erosion
physical weathering
The photograph below shows a steep-sided rock formation that is over 100 meters high. This landscape feature is located in an arid region. What would happen to this landscape feature if the climate became more humid?
ess weathering and erosion, producing a more rounded landscape feature
less weathering and erosion, producing a more angular landscape feature
more weathering and erosion, producing a more rounded landscape feature
more weathering and erosion, producing a more angular landscape feature
This graph shows the effect that average yearly precipitation and temperature have on the type of weathering that will occur in a particular region. Which type of weathering is most common where the average yearly temperature is 5°C and the average yearly precipitation is 45 cm?
moderate chemical weathering
very slight weathering
moderate chemical weathering with frost action
slight frost action
This graph shows the effect that average yearly precipitation and temperature have on the type of weathering that will occur in a particular region. The amount of chemical weathering will increase if...
air temperature decreases and precipitation decreases
air temperature decreases and precipitation increases
air temperature increases and precipitation decreases
air temperature increases and precipitation increases
The demonstration shown in the diagram below indicates that powdered limestone reacts faster than a single large piece of limestone of equal mass when both are placed in acid. The most likely reason powdered limestone reacts faster is that it has...
ess total volume
more chemical bonds
more total surface area
lower density
Adding automobile exhaust gases to the atmosphere has had the greatest impact on landscape development by
changing the position of crustal plates
changing Earth’s prevailing wind patterns
increasing the rate of chemical weathering
increasing the amount of ozone in ground water
The four limestone samples illustrated below have the same composition, mass, and volume. Under the same climatic conditions, which sample will weather fastest?
The diagram below represents the size and shape of a pebble. This pebble and 20 other pebbles having a similar size and shape were placed in a rock tumbler with water and allowed to abrade for five days.
Which diagram best represents the size and shape of this pebble after the five-day period
The photograph below shows wire netting installed over a steep rock outcrop. This wire netting has been installed to prevent loss of property or life resulting from
crosscutting and downwarping
folding and faulting
weathering and erosion
high winds and flooding
