Front

What is the Mohs scale of hardness?

Back

The Mohs scale of hardness is a scale used to measure the hardness of minerals, ranging from 1 (talc) to 10 (diamond).

Front

What does heat and pressure do to rocks?

Back

Heat and pressure can change existing rocks into metamorphic rocks.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are rocks that have been changed from their original form due to heat and pressure.

Front

Why is streak more reliable than color for identifying minerals?

Back

Streak is more reliable because mineral colors can vary, but the streak color remains consistent.

Front

What is the difference between igneous, sedimentary, and metamorphic rocks?

Back

Igneous rocks form from cooled magma or lava, sedimentary rocks form from compressed sediments, and metamorphic rocks form from existing rocks changed by heat and pressure.

Front

What is an example of a metamorphic rock?

Back

An example of a metamorphic rock is marble, which forms from limestone.

Front

What is the process of cooling/crystallization?

Back

Cooling/crystallization is the process where molten rock cools and solidifies to form igneous rocks.

Front

What is deposition in geology?

Back

Deposition is the process where sediments are laid down in new locations, often forming sedimentary rocks.

Front

What is compaction in geology?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume.
