| Question | Answer |
|---|---|
| Weathering | The breakdown of rocks |
| Deposition | The depositing of rocks and materials in a new location as sediment. |
| Sedimentary Rocks | Rocks that have layers of sediments cemented together. |
| 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. |
| Mantle | One of the outermost layers of Earth composed primarily of rocky material. |
| Inner Core | The innermost layer of Earth composed of iron and nickel. |
| Outer Core | One of the innermost layers of Earth composed of iron and nickel. |
| 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. |
