9.1 Weathering (Regents Earth Science)

Front

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?

Back

Enlargement of the cracks occurs because water expands when it freezes.

The composition of residual soil is most likely determined by the

Back

type of bedrock material

Front

Which property of water makes frost action a common and effective form of weathering?

Back

Water expands when it freezes.

Front

Which event is an example of chemical weathering? Options: 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

Back

acid rain reacting with limestone bedrock

Front

Chemical weathering occurs most rapidly in climates which are

Back

moist and warm

Front

Which is the best example of physical weathering? Options: 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

Back

the cracking of rock caused by the freezing and thawing of water

The action of the root splitting the bedrock is an example of

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?

Back

more weathering and erosion, producing a more rounded landscape feature

Front

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...
