Earth Science Geology Review

Front

What is schist?

Back

A foliated metamorphic rock that shows mineral alignment but not banding, containing medium-sized grains of quartz and pyroxene.

Front

What sedimentary rock forms from particles with diameters ranging between 0.01 cm to 0.1 cm?

Back

Sandstone, formed through the burial and cementation of sand-sized particles.

Front

What map symbol represents rock formed from the evaporation of seawater?

Back

Evaporite rock symbol.

Front

What is gneiss?

Back

A foliated metamorphic rock characterized by coarse-grained bands of minerals such as amphibole, quartz, and feldspar.

Front

What does the glassy texture of obsidian indicate about its formation?

Back

It indicates that obsidian formed quickly on Earth's surface.

Front

Define foliated texture in rocks.

Back

A texture in metamorphic rocks where minerals are aligned in planes or bands.

Front

What is the primary process that forms sedimentary rocks?

Back

The processes of burial, compaction, and cementation of sediments.

Front

What are the main types of rocks in the rock cycle?

Back

Igneous, sedimentary, and metamorphic rocks.

Front

How does quartzite form?

Back

Quartzite forms from the metamorphism of sandstone, resulting in a hard, non-foliated rock.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

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