Geology Quiz: Rocks and Minerals

What is the primary difference between a rock and a mineral?

• A mineral is a naturally occurring solid with a specific atomic structure.

• A rock is a naturally occurring solid made of one type of mineral.

• A mineral is made of multiple rocks.

• A rock is a liquid form of minerals.

How are igneous rocks formed?

• By the compression of sediments.

• Through the cooling and hardening of magma.

• By the transformation of existing rocks under pressure.

• By the accumulation of organic material.

What is a characteristic of extrusive igneous rocks?

• They form deep within the Earth.

• They cool quickly and have small crystals.

• They are formed by the compression of sediments.

• They have large crystals.

What process leads to the formation of sedimentary rocks?

• Compression and cementation of sediments.

• Cooling of magma.

• Transformation under heat and pressure.

• Evaporation of water.

Which environment is most likely to have sedimentary rocks?

• Mountain peaks.

• Deep ocean trenches.

• Volcanic regions.

• Lake beds and riverbeds.

What is the main factor in the formation of metamorphic rocks?

• Cooling of lava.

• Accumulation of sediments.

• Heat and pressure causing transformation.

• Erosion by wind and water.

Which rock is an example of a metamorphic rock?

• Granite

• Sandstone

• Marble

• Basalt
