Igneous Rocks | Rocks that have melted and cooled. Ex. Lava and magma |
Metamorphic Rocks | Rocks that were changed by heat and pressure. |
Fossils | Items that provide information about life and conditions of the past. |
Earth's Crust | The thinnest layer of Earth composed primarily of rocky material. |

Thermal Energy | Heat energy |
Plate Tectonics | Large rigid blocks (plates) that interact with each other at their boundaries. |
Convergent Boundaries | These occur when the plate tectonics move together causing mountain ranges on land and trenches underwater. |
Divergent Boundaries | These occur when the plate tectonics move apart on the ocean floor. They form volcanoes and mountain ranges underwater. |
Transform Boundaries | These occur when the plate tectonics slip past each other horizontally. They cause earthquakes. Also called strike- slip or sliding boundaries. |
