Geology Part 2-Rocks and Minerals

Front

What is igneous rock?

Back

Igneous rock is formed from the cooling and solidification of magma or lava.

Front

What conditions transform igneous rock into metamorphic rock?

Back

Igneous rock can be transformed into metamorphic rock if it is heated and put under pressure for long periods of time.

Front

What is a streak test?

Back

A streak test is a method used to determine the color of a mineral in powdered form by rubbing it against a porcelain plate.

Front

How are rocks different from minerals?

Back

Rocks are made up of one or more minerals, while minerals are not made up of rocks.

Front

What type of rock is formed from the weathering and erosion of metamorphic rock?

Back

Sedimentary rock is formed from the weathering and erosion of metamorphic rock.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process by which rocks are transformed from one type to another through various geological processes.

Front

What is sedimentary rock?

Back

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

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that are changed by heat, pressure, or chemically active fluids.

Front

What is the difference between magma and lava?

Back

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

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals through natural forces such as wind, water, and temperature changes.
