Rock & Mineral Flashcard

Front

What process forms both metamorphic and sedimentary rock?

Back

Compacting is the process that forms both metamorphic and sedimentary rock.

Front

What is true about rocks?

Back

Rocks are made of one or more minerals.

Front

What does the Moh's scale measure?

Back

The Moh's scale measures the hardness of minerals.

Front

What does the size of a mineral crystal indicate about the magma from which it was formed?

Back

The size of a mineral crystal can indicate the cooling rate of the magma.

Front

What processes must occur for an igneous rock to change into a metamorphic rock?

Back

Heating and pressure are required for an igneous rock to change into a metamorphic rock.

Front

Define metamorphic rock.

Back

Metamorphic rock is formed from existing rock that has been changed by heat, pressure, or chemically.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

Explain the rock cycle.

Back

The rock cycle is the continuous process of rock formation and transformation between igneous, sedimentary, and metamorphic rocks.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is magma that has reached the surface.

Front

What is the significance of the cooling rate of magma?

Back

The cooling rate of magma affects the size of mineral crystals formed in igneous rocks.
