Rocks and Minerals Unit Review

Which type of rock is a foliated metamorphic rock? granite marble quartzite slate

slate

Which type of rock forms when molten material cools and hardens inside Earth? an igneous rock an extrusive rock a rock with fine texture a rock with small crystals

an igneous rock

Which phrase describes a metamorphic rock? formed from a volcano was once buried underground formed from evaporating water contains minerals that have not changed

was once buried underground

Which statement describes the relationship between minerals and rocks? Minerals and rocks are the same. Aggregates of minerals form rocks. Minerals determine the texture of a rock. Most rocks are made of a single mineral type.

Aggregates of minerals form rocks.

Study the image of this rock. Which characteristic best supports its formation from sedimentary processes? It has many layers. It is coarse-grained. Its grain shape is round. Its texture is non-banded.

It has many layers.

An igneous rock has small, dark crystals. Which statement also accurately describes this rock? It is an intrusive rock. It has a coarse texture. It was found on Earth's surface. It was formed from slow cooling.

It was found on Earth's surface.

During the formation of metamorphic rocks, what is one event that leads to increased heat? Sun warms rocks. Magma pockets rise. Friction occurs between sliding rocks. Lava at Earth's surface flows over rocks.

Magma pockets rise.

Which statement describes one role of minerals during cementation? Minerals bind sediments together. Compressed minerals form new rock. Sediments dissolve and bind minerals together. Spaces between minerals are filled with sediments.

Minerals bind sediments together.

Which processes contribute to the formation of chemical sedimentary rocks? Organisms decay in a solution. Minerals dissolve and crystalize. Rock fragments squeeze together. The remains of plants and animals.

Minerals dissolve and crystalize.

Which property is used to identify the origin of an igneous rock? color density hardness crystal size

NOT: hardness (MOST LIKELY: crystal size)

During the formation of metamorphic rocks, what most likely causes pressure to increase? Magma pockets rise. Gravity pulls on rocks. Rocks melt deep beneath Earth's surface. Rocks beneath Earth's surface are forced toward the mantle.

Rocks beneath Earth's surface are forced toward the mantle.

As streams flow through Stone Mountain, layers of sand build up. Over time, the sand particles form a sedimentary rock called sandstone. What causes sandstone to change into metamorphic rock at Stone Mountain? Sandstone is reshaped by erosion from a stream. Sandstone builds up layers of sand at the mountain. Sandstone experiences intense heat and pressure. Sandstone has more sand particles compacted on top of it.

Sandstone experiences intense heat and pressure.

Study the image. Which statement best describes the rock? The rock has fine grains. The grains of the rock are sharp or jagged. The rock is banded. The bands of the rock run from the top to the bottom.

The rock has fine grains.

In the formation of metamorphic rocks, what effect do temperature and pressure primarily have? They erode rocks. They create layers. They make rocks smaller. They change existing minerals.

They change existing minerals.

Study this image. Which statement best describes the rock shown? The grains of this rock are jagged. The grains in this rock are tiny. This rock has a non-banded pattern. The color of this rock is determined by its texture

This rock has a non-banded pattern.
