Which type of rock appears to be the most easily eroded by the
river in this area?
Shale
Basalt
Sandstone
Limestone
The picture shows the layers in the bank of a river. The differences in the size of
the particles in the layers are most likely caused by differences in the types of plants living on
the bank
types of animals
digging in the
sediments
thickness of winter ice
in the river
speed of the water
carrying the sediments
Sinkholes associated with natural processes are
characteristic of what type of bedrock?
Granite
Basalt
Limestone
Gneiss

affected the most by weathering and erosion?

Government programs to reduce acid rain have resulted in cleaner emissions
from U.S. industries in recent years. As a result, the sulfate concentration in
rainwater has declined significantly. But the sulfate concentration in some lakes is
showing little, if any, change. Why might this be true?
The sulfate in American lakes is actually coming
from industries in Europe and Asia.
Sulfate that accumulated earlier in the soil is still
being flushed into the lakes by run-off.
Individual industries produce fewer emissions but
the amount of precipitation has increased.
There is no connection between emissions
from industry and the acidity of lake water.
The breakdown of rocks and minerals into smaller particles without a change in
composition is called mechanical weathering
igneous intrusion
chemical precipitation
metamorphic foliation
Limestone chips dissolve after they are placed in a beaker of dilute acid. Which
geologic process is this most similar to?
Folding
Weathering
Subduction
Faulting
Which of the following best explains the rolling topography of the Valley and
Ridge province in Virginia?
Ocean currents and uplift
Block faulting of marine sediments
Rifting and ocean waves
Folding and differential erosion
Which of the following is not considered a result of the movement of tectonic
plates?
Earthquakes
Karst topography
Mountain ranges
Increased volcanic activity

Which recent geologic processes commonly occur in the Coastal Plain region of
Virginia?
Erosion and deposition
Subduction and metamorphism
Crustal uplift and rock deformation
Rifting and intrusion
Rocks formed by the cementing of weathered materials are called extrusive igneous rocks
magma
basalt
sedimentary rocks
