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
physical weathering
chemical weathering
mass movement
deposition
The map below shows a meandering stream. Points A, B, C, and D represent locations along the stream bottom. At which location is the greatest amount of sediment most likely being deposited?
A
B
C
D
The bedrock at a certain location is deeply scratched, and in some places is covered by a layer of unsorted sediment. Which erosional agent was probably responsible for these features?
ocean waves
running water
glaciers
wind
The natural sandblasting (abrasion) of surface bedrock in a desert region is the result of
wind erosion
wave erosion
mass movement
chemical precipitation
Landscapes will undergo the most chemical weathering if the climate is
cool and dry
cool and wet
warm and dry
warm and wet
The diagram below represents a stream valley. Which diagram below best shows how this valley might be modified after a glacier has moved through it?
The map below shows the top view of a meandering stream as it enters a lake. At which points along the stream are erosion and deposition dominant?
Erosion is dominant at A and D, and deposition is dominant at B and C.
Erosion is dominant at B and C, and deposition is dominant at A and D.
Erosion is dominant at A and C, and deposition is dominant at B and D.
Erosion is dominant at B and D, and deposition is dominant at A and C.
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

Esopus and Oriskany
New Scotland, and Schenectady and Indian Ladder beds
Onondaga and Coeymans
Schoharie, and Marcellus and Hamilton

A
B
C
D
The diagram below shows a meandering stream flowing across nearly flat topography and over loose sediments. If arrow length represents stream velocity, which diagram best shows the relative stream velocities in this section of the stream?
