Question

1. water is a major agent of chemical weathering because water

(1) cools the surroundings when it evaporates
(2) has a density of about one gram per cubic centimeter
(3) has the highest specific heat of all common earth materials
(4) dissolves many of the minerals that make up rocks

1. by which processes are rocks broken up and moved to different locations?

(1) burial and cementation
(2) compaction and transportation
(3) evaporation and condensation
(4) weathering and erosion

1. the mineral composition of a residual soil is most affected by the

(1) type of bedrock material
(2) steepness of hillslopes
(3) elevation of the surface
(4) depth of the water table

1. what are two major factors that control the development of soil in a given location?

(1) vegetative cover and slope
(2) bedrock composition and climate
(3) tectonic activity and elevation
(4) erosion and transpiration

1. which change in climate would most likely cause the greatest increase in chemical weathering of local bedrock?

(1) lower temperature in winter
(2) higher atmospheric pressure in summer
(3) lower humidity in winter
(4) greater precipitation in summer

1. impact craters are more obvious on the moon and mercury than on earth because

(1) all meteorites burn up in earth’s atmosphere
(2) meteorites have not struck earth
(3) weathering processes on earth have removed most craters
(4) earth is younger than mercury or the moon

1. 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
(1) physical weathering
(2) erosion
(3) deposition
(4) chemical weathering
