|---|
| rock | mixture of minerals, rock fragments, volcanic glass, organic matter |
| rock cycle | demonstrates how rocks are created and changed |
| law of conservation of matter | matter is not created or destroyed but particles are re-arranged |
| magma | hot melted rock beneath earth's surface |
| intrusive rocks | igneous rocks that form from magma |
| extrusive rocks | igneous rocks that form on earth's surface |
| basaltic | dense dark colored rock |
| granitic | light less dense colored rocks |
| mixture of basaltic and granitic | andesitic |
| metamorphic | rocks that change due to temperature, pressure and hot watery fluids |
| foliated | mineral grains line up in parallel layers |
| non foliated | mineral grains grow and arrange but don't line up in layers |
| sediments | loose particles that have been moved by water, wind, gravity or ice |
| sedimentary | formed when sediments are pressed and cemented together |
| sedimentary rocks | forms in layers |
| detrital | made from broken fragments of rocks |
| weathering | process of rocks breaking down into smaller peices |
| erosion | movement of weathered material |
| compaction | sediments are deposited, layers build up and cause pressure and sediments stick together |
| cementation | minerals are deposited by water, and act like glue and sediments are "cemented" together |
