Geology Unit Lesson Two Quiz

A divergent plate boundary is a boundary at which two tectonic plates move away from each other. As the plates move apart, magma rises upward between them and erupts onto the ocean floor as lava. This lava cools quickly to form solid rock. Over time, these hardened lava flows build up on top of each other and are uplifted by tectonic forces to form mid-ocean ridges.

Based on this information, what type of rock are mid-ocean ridges made of?

• metamorphic rock

• igneous rock

• fossilized rock

• sedimentary rock

The effects of freezing and thawing, plant roots, acid and other forces on rock.

• Compaction

• Deposition

• Cementation

• Erosion

• Weathering

The process where water, wind, or ice carry away bits of broken rock

• Compaction

• Deposition

• Cementation

• Erosion

• Weathering

The process in which the sediment settles

• Compaction

• Deposition

• Cementation

• Erosion

• Weathering

he process that presses sediment together

• Compaction

• Deposition

• Cementation

• Erosion

• Weathering

The process in which dissolved minerals crystalize and glue particles of sediment together

• Compaction

• Deposition

• Cementation

• Erosion

• Weathering

Michelle studies the sample of rock shown below. Michelle decides that the sample is from a sedimentary rock. Which sentence explains why Michelle classifies the sample as sedimentary rock?

• The layers show that the rock was formed by a single element under high pressure.

• The layers show that the rock was formed by a single element under extreme heat.

• The layers show that the rock was formed by one or more minerals that cooled very quickly.

• The layers show that the rock was formed by one or more minerals that compacted over time.

How are sedimentary rocks made?

• They are formed when layers of loose debris get cemented together at the Earth's surface.

• They are formed when magma cools deep in the Earth's crust and is exposed to air after volcanic action.

• They are formed when igneous rock crystallizes.

• They are formed when rock minerals are changed by a new environment.

Igneous, sedimentary, and metamorphic rocks are found at the same cliff side. Which statement is correct about the rocks at this location?

• All three types of rock will become metamorphic if they stay at the surface of Earth.

• If this location is buried deep underground, only the metamorphic rock will melt because it has already been heated before.

• The metamorphic rock and sedimentary rock were already at this location and magma flowed into the other rocks.

• The igneous rock will become metamorphic rock after the rock in the cliff side turns into sediment.
