Rocks and Minerals Quiz

The volcano Kilauea, on the big island of Hawaii, is erupting and lava is ejected from the volcano vent. The lava solidifies to form what type of rock?

• extrusive igneous rock

• sedimentary rock

• intrusive igneous rock

• metamorphic rock

The Nile River carries sediments to the ocean. Over time, the sediments are compressed as more sediments are deposited on top of them. Which type of rock will be formed?

• intrusive igneous rock

• metamorphic rock

• extrusive igneous rock

• sedimentary rock

Off the coast of the Pacific Northwest in the United States, the Pacific plate is being pushed underneath the North American plate in a subduction zone caused by plate tectonics. As the rock from the Pacific plate is pushed under the North American plate, it is subjected to high temperatures and pressures. Which rock will be created from this process?

• sedimentary Rock

• intrusive igneous rock

• metamorphic rock

• intrusive igneous rock

In the Arizona Desert, a sudden rainstorm washes sand and sediment into the Colorado River, which eventually deposits the sediments into the ocean. This process is called:

• erosion & transport

• deposition

• weathering

In the desert, wind picks up and carries fine particles of sand and dirt. As the wind blows against the rocks, the particles rub against the rocks and wear them down in a process called:

• weathering

• transport

• erosion

Which one of the following is NOT one of the three types of rock?

• 
  sedimentary

• lava

• metamorphic

• igneous

True or False? Magma is lava that has been ejected from beneath the Earth’s crust through a volcano.

• True

• False

How do sedimentary rocks form?

• An already existing rock heats up but cools off before it can melt

• An already existing rock melts and cools off

• An already existing rock is taken apart into sediments and different sediments compact together over time

Which cools faster: intrusive or extrusive rock?

• intrusive Rock

• extrusive Rock

• neither

Name two names that classify igneous rocks.

• foliated/non-foliated

• intrusive/extrusive

• metamorphic/sedimentary
