Geology Part 2- Rock 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 metamorphic rock?

Back

Metamorphic rock is formed from existing rock types (igneous, sedimentary, or other metamorphic rocks) that have 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

What is the Mohs Scale of Mineral Hardness?

Back

The Mohs Scale is a scale that ranks minerals based on their ability to scratch one another, from 1 (talc) to 10 (diamond).

Front

What is a streak test?

Back

A streak test is performed by rubbing a mineral against a porcelain plate to observe the color of its powder.

Front

What is the difference between igneous and sedimentary rock?

Back

Igneous rock forms from cooled magma or lava, while sedimentary rock forms from the accumulation of sediments.

Front

What is a mineral?

Back

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure.

Front

What is the process of metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks due to heat, pressure, or chemically active fluids.

Front

What is the best way to identify a mineral?

Back

The best way to identify a mineral is by examining its physical properties, such as color, streak, hardness, and luster.
