Sandstone, shale, conglomerate and coal are all examples of:

• sediment
• sedimentary rock
• igneous rock
• metamorphic rock

Water freezing and expanding the cracks in a rock is an example of:

• erosion
• chemical weathering
• mechanical weathering
• cementation

A section of missing sedimentary rock due to erosion is called a(n):

• deposit
• unconformity
• index fossil
• intrusion

Geologists map the interior of the Earth using:

• light waves
• sound waves
• seismic waves
• ocean waves

Which layer of the Earth are the tectonic plates made of?

• crust
• mantle
• asthenosphere
• lithosphere

What causes continents to "drift"?

• seafloor spreading
• subduction
• the tides
• rotation of the Earth

_________ in modern India demonstrate that it must have once been connected to Antarctica.

• Coal deposits

• Fossils

• Mountains

• Glacial scarring

At a divergent boundary, you are likely to find a(n):

• subduction zone
• trench
• mid-ocean ridge
• island arc

Where in the world would you find a divergent plate boundary on land?

• Great Rift Valley (Africa)
• San Andreas fault (California)
• Andes Mountains (South America)
• Yellowstone National Park (Wyoming)

An island arc tends to form between:

• two converging continental plates
• two converging oceanic plates
• two diverging oceanic plates
• an oceanic plate subducting beneath a continental plate
