Physical and Chemical Weathering

Which characteristic would most likely remain constant when a limestone cobble is subjected to extensive the physical weathering of abrasion?

• shape

• mass

• size

• composition

Which type of climate has the greatest amount of rock weathering caused by frost action?

• a wet climate in which temperatures remain below freezing

• a wet climate in which temperatures alternate from below freezing to above freezing

• a dry climate in which temperatures remain below freezing

• a dry climate in which temperatures alternate from below freezing to above freezing

By which processes are rocks broken up and moved to different locations?

• evaporation and condensation

• weathering and erosion

• burial and cementation

• compaction and transportation

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

Rock samples brought back from the Moon show absolutely no evidence of chemical weathering. This is most likely due to

• the lack of an atmosphere on the Moon

• extremely low surface temperatures on the Moon

• lack of biological activity on the Moon

• large quantities of water in the lunar "seas"

Most sediments found on a beach are likely to be:

• angular and weathered from underlying bedrock

• angular and weathered from bedrock upstream

• rounded and weathered from underlying bedrock

• rounded and weathered from bedrock upstream

Chemical weathering will occur most rapidly when rocks are exposed to the:

• hydrosphere and lithosphere

• mesosphere and thermosphere

• hydrosphere and atmosphere

• lithosphere and atmosphere

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 one gram per cubic centimeter

• has the highest specific heat of all common earth materials
