1.) a thick and mostly flattened layer of cooled lava is called a volcanic crater.

a
true

b
false

2.)slate is a metamorphic rock that forms from shale, which is a sedimentary rock. which of the following would be needed for shale to form from slate?

a
increased heat

b
increased pressure

c
erosion and deposition

d
melting and solidification

3.)stress that stretches rocks and makes them thinner is called compression.

a
true

b
false

4.)what causes an earthquake to happen?

a
rocks along an underground fault move suddenly and release energy.

b
surface rocks move suddenly as a result of physical stress.

c
energy is transferred to rock layers from convection currents in the oceans and the atmosphere.

d
large amounts of rock suddenly shift downward when large holes form under them.

5.)earth's physical layers correspond to earth's compositional layers. which part of the mantle is also part of the lithosphere?

a
the rigid upper part

b
the soft-moving part

c
the lower stationary part

d
the fluid, hot part

6.)which of the following events can produce an earthquake?

a
the violent shaking of sections of the lithosphere

b
a sudden release of energy from the mantle

c
the force of tsunamis in the oceans

d
movement of tectonic plates along a fault

7.)the composition of sedimentary rock shows the source of the sediment that makes up the rock. which of the following would provide the best evidence of how the rock formed?

a
the rock's age

b
the rock's texture

c
the rock's color

d
the rock's fossil content

8.)the inner core is thought to be a liquid layer of the earth's core.

a
true

b
false

9.)
which of the following is the correct definition for the term epicenter?

a
the position on earth's surface where an earthquake begins

b
the position on earth's surface directly above an earthquake's focus

c
the position below earth's surface where an earthquake begins

d
the position along a fault directly below an earthquake's focus

10.)rainwater can break down rocks by dissolving minerals in the rocks. acid rain is rainwater that is more acidic than normal rainwater. acid rain can dissolve the minerals in rocks faster than normal rainwater can. how does acid rain affect different types of rock?

a
it changes sedimentary and igneous rocks into metamorphic rocks.

b
it causes metamorphic and sedimentary rocks to melt and form igneous rocks.

c
it dissolves some rocks faster because of their different compositions.

d
it causes an equal amount of weathering in all types of rock.
