1. Review for Rock Study Guide

2. Rock Rock is naturally occurring solid of one or more minerals or organic materials Sediments are all rocks that have been weathered and eroded into piece (scientific) Fragments (not scientific) Magma—hot fluid materials which are liquid rocks under the earth’s surface

3. Igneous Extrusive: has tiny small wholes or small crystals – Formed from cooling magma above earth’s surface Intrusive: large crystals are formed – Underneath the earth’s surface – Malfic– igneous rocks that are dark in color due to their composition—what minerals make it up – Felsic—igneous rocks that are light in color due to their composition

4. Sedimentary Weathering and erosions of all rocks. The creation strata (layers) formed through a process stratification Erosion—moving of sediments Clastic: sediments that have been cemented together Chemical: dissolving salt—usually can see strata (Layers) Organic: sediments connects by fossils

5. Metamorphic Foliated: minerals are arranged in bands or plains Nonfoliated: minerals are not arranged in bands or plains 50c to 1000c Contact: near magma Regional: earthquakes or rocks moves
