CLASTIC
Sedimentary Rocks
composed of weathered bits of rocks and minerals
dissolved substances precipitate, or separate, from water
Formed when igneous rock is weathered and eroded and settles at the bottom of oceans and lakes.
Appearance: course to fine grained
Appearance: course to fine grained crystalline
Examples: conglomerate, sandstone, siltstone, shale

9. 3.4 Metamorphic Rocks Formation of Metamorphic Rocks
 Contact metamorphism occurs when magma moves into rock.
Occurs near a body of magma
Changes are driven by a rise in temperature.

10. 3.4 Metamorphic Rocks Formation of Metamorphic Rocks
 Regional metamorphism results in large-scale deformation and high-grade metamorphism.
Directed pressures and high temperatures occur during mountain building.
Produces the greatest volume of metamorphic rock
