Earth Science Unit 4 Rocks Review

Igneous rock texture formed from two different rates of cooling resulting in both large and small mineral crystals.

Refers to the relationship between the materials of which the rock is composed (igneous fine grained/coarse grained, metamorphic foliated/unfoliated, sedimentary silt/sand/cobble).

ES.5

Sedimentary rock not formed from other rock or rock particles; can be classified as chemical or organic.

• Porphyritic

• Nonclastic

• Clastic

• Texture

Process of sediments being tightly packed due to the weight of the overlying layers of sediment.

• Compaction

• Cementation

• Felsic

• Mafic

Process by which rock fragments are bonded together into sedimentary rock.

• Compaction

• Cementation

• Felsic

• Mafic

Igneous rock rich in magnesium and iron, usually dark in color and includes basalt.

• Compaction

• Cementation

• Felsic

• Mafic

Igneous rock consisting mostly of feldspars and other light colored minerals, includes granite.

• Compaction

• Cementation

• Felsic

• Mafic

Liquefied by heat, magma below ground and lava above ground.
