THREE TYPES OF ROCKS

IGNEOUS ROCK

SEDIMENTARY ROCKS

CLASTIC SEDIMENTARY ROCKS

Weathering and Erosion TransportationDeposition Compaction and Cementation Sedimentary Rock

ORGANIC SEDIMENTARY ROCKS

Primarily made from the remains of once living things

The Good Earth, Chapter 7: Rocks and Minerals May form from the remains of dead organisms − Chalk formed from billions of coccoliths, round plates of calcite from microscopic (clay-sized) coccolithophore organisms − Chalk is a type of limestone Biochemical Sedimentary Rocks BIOCHEMICAL SEDIMENTARY ROCKS

The Good Earth, Chapter 7: Rocks and Minerals Two types of metamorphism 1.Contact metamorphism Changes due to increases in temperature where rocks come in contact with heat source (e.g. magma chamber) − Example: limestone around a magma chamber is baked by the heat to form marble Marble (above) and limestone have similar composition but marble typically has a larger grain size METAMORPHIC ROCKS
