|---|---|
| Igneous Rock | Rock formed from Magma |
| The Thee factors that effect whether a rock melts | temperature, pressure, and the presence of fluids in the rock. sometimes when extra pressure is removed from the rock. |
| Partial Melting | When different minerals in a rock have have different melting points. |
| Highest Melting Points=????? | Crystallizes first!!!!!!!!! |
| Fractional Crystallization | Crystallization and removal of different minerals when cooling. These are the biggest rocks. |
| Sedimentary Rocks | Rocks that are formed from sediment that is squeezed together. |
| Metamorphic Rock | Existing Rocks that change their form. |
| Bowen's Reaction Series | A pattern that shows how crystals form when magma is cooling. |
| More Resistant to to weather=????? | The higher number of bonds it will have. |
| Chemical Stability | the better a rock is at keeping its chemical compounds the more stable it is. |
| Intrusive Igneous Rock | Magma that cools inside the crust |
| Extrusive Igneous Rock | Lava that cools at the Earth's surface. |
| Porphyritic texture | Igneous Rock that has a mixture of large and small crystals |
