Rock Cycle-Continuous changing and remaking of rocks Any of the 3 types

of rocks can be transformed into another type of rock by natural Earth processes

Igneous rocks are formed from the crystallization of magma Granite-Makes up Earth’s continental

crust Basalt-Makes up Earth’s oceanic crust

Sedimentary rocks are rocks that were formed through the deposition and solidification of sediments Sediments-Pieces of solid

material Sandstone, Limestone

Metamorphic rocks form when rocks are changed by heat and/or pressure

The heat allows atoms to rearrange themselves Gneiss, Marble

Igneous Rock Formation: Sedimentary and

Metamorphic rocks can be melted down, and then cooled to form igneous rocks

Sedimentary Rock Formation: Igneous or Metamorphic rocks can

become weathered and eroded and then lithified (cemented together) into sedimentary rocks

Metamorphic Rock Formation: Igneous and Sedimentary Rocks can be

transformed by heat or pressure to form metamorphic rocks
