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
In which climate would the chemical weathering of limestone occur most rapidly?
cold and dry
cold and humid
warm and dry
warm and humid
Which factor has the greatest influence on the weathering rate of Earth’s surface bedrock?
local air pressure
age of the bedrock
angle of insolation
regional climate
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
