Earth and Space Science CHAPTER 4 Earth's Minerals and Rocks

Front

What type of rock is formed by the deposit of sediments compacted together?

Back

Sedimentary rock is formed by the deposition and compaction of sediments.

Front

True or False: Metamorphic rocks are altered by heat and pressure.

Back

TRUE: Metamorphic rocks are formed when existing rocks are subjected to heat and pressure.

Front

What does a mineral's cleavage describe?

Back

A mineral's cleavage describes the pattern or patterns according to which it breaks.

Front

Where are sedimentary rocks most likely found?

Back

Sedimentary rocks are most likely found in environments like river deltas.

Front

What type of sedimentary rock is formed by the crystallization of chemical precipitates?

Back

Chemical sedimentary rocks are formed by the crystallization of chemical precipitates.

Front

Define igneous rock.

Back

Igneous rock is formed from the solidification of molten material called magma or lava.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation through geological processes.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

What is a mineral?

Back

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