crust
B.
inner core
C.
mantle

melting and hardening
B.
cooling and heating
C.
deposition and cementing
D.
uplifting and faulting
5. Lithospheric plates have moved to form land formations on the Earth's surface. Which land
formation occurs as a result of the plates folding upon one another?

8. A glacier retreats leaving bare rocks. Lichens begin to live on the rocks. The lichens produce an
acid that starts to break down the rocks. How will this process affect the environment?
A.
It will put acid into the lakes and ponds.
B.
It will begin the process of building soil.
C.
It will prevent the carbon cycle from occurring.
D.
It will prevent bacteria from invading the ecosystem.
9. Which of the following helped in the development of the theory of plate tectonics?
A.
measuring the depth of oceans near deep-sea trenches
B.
detecting magnetic striations on land once covered by glaciers
C.
understanding the ways organisms adapted to topographical changes
D.
understanding rock formations of a similar age occurring on two separate continents
10. Between 40 and 50 million years ago, the landmass on the Indian plate collided with the
landmass on the Eurasian plate. What formed when these landmasses collided?
A.
the Grand Canyon
B.
the Great Plains
C.
the Himalayan Mountains
D.
the Mariana Trench
11. The islands in the mid-Pacific Ocean region were formed by
A.
land subsidence.
B.
deposition from currents.
C.
wind and water erosion.

B.
molten rock
C.
liquid metal
D.
