100 Minerals Sedimentary Rocks Igneous Rocks Metamorphic Rocks Rock Cycle

A naturally occurring, inorganic solid with a definite crystalline structure Column 1, 100

One example of a mineral that is also a metal Column 1, 200

A valuable, highly priced mineral that is rare (general term + one example) Column 1, 300

Property of minerals that is also a property of metals and refers to light being reflected Column 1, 400

Minerals that break along smooth, flat surfaces have this property Column1, 500

Rock type formed from recombining sediments Column 2, 100

During this process, pressure from overlying layers pushes sediment together Column 2, 200

During this process, sediments get bound tightly together or “glued” together Column 2, 300

Two forms of weathering that break rocks into sediments Column 2, 400

Organic sedimentary rocks have large amounts of this Column 2, 500

Rocks formed by the melting of molten material Column 3, 100

This type of igneous rock is formed within the volcano from cooling magma Column 3, 200

This type of igneous rock is formed from cooling lava on the surface of the Earth Column 3, 300

This type of igneous rock can take hundreds or thousands of years to form Column 3, 400

This type of igneous rock has smaller mineral crystals than the other type Column 3, 500

This part of the term metamorphic means 'to change' Column 4, 100

Two ways that rocks can transform into metamorphic rocks Column 4, 200

This type of metamorphic rock has mineral grains that are lined up in parallel bands and look like stripes Column 4, 300

This type of metamorphic rock has mineral grains that are rearranged without any specific pattern Column 4, 400

This is the kind of metamorphic rock that results when granite (an igneous rock) is put under pressure Column 4, 500

When lava or magma cools, this type of rock is formed Column 5, 100

When a rock is exposed to weathering and erosion, this is the result Column 5, 200

When sediments are compacted and cemented, they become this type of rock Column 5, 300

When sedimentary or igneous rocks experience heat or pressure, this is the type of rock they become Column 5, 400

This is what results from melted rock of any type (usually below the surface of the Earth) Column 5, 500
