SCI: Ch6.L2 Types of rocks & Rock Cycle Review

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?

• Sedimentary

• Metamorphic

• Igneous

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

• Sedimentary

• Metamorphic

• Igneous

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

• Metamorphic

• Igneous

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

• Melting

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

These rocks have fossils or imprints of leaves, shells or insects. They experience pressure over time.

• igneous

• metamorphic

• sedimentary

This type of rock is made beneath the surface of the earth. It has ribbon-like layers, caused by the heat. Some of these rocks have shiny crystals on them, they changed.

• Sedimentary

• Igneous

• Metamorphic

Deep inside the earth rocks are melted or molten and become magma.

• Sedimentary

• Igneous

• Metamorphic
