Front

What is the rock cycle?

Back

The rock cycle is the process by which rocks are continually changing, and any type of rock may be transformed into another type by appropriate processes.

Front

What type of rocks are formed from the compaction and cementation of layers of sand, silt, clay, and mud?

Back

Sedimentary rocks.

Front

According to Moh's Scale of Mineral Hardness, which mineral can scratch gypsum but not apatite?

Back

Calcite.

Front

How are igneous rocks formed?

Back

Igneous rocks are formed by volcanic activity.

Front

What property is tested when performing a scratch test on a mineral?

Back

Hardness.

Front

What are sedimentary rocks?

Back

Rocks that form from the accumulation and compaction of mineral and organic particles.

Front

What is the difference between igneous and metamorphic rocks?

Back

Igneous rocks form from cooled magma or lava, while metamorphic rocks form from existing rocks that have been changed by heat, pressure, or chemical processes.

Front

What is the definition of a mineral?

Back

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

Front

What is the Moh's Scale of Hardness?

Back

A scale that ranks minerals based on their ability to scratch one another, from 1 (talc) to 10 (diamond).

Front

What is weathering?

Back

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