| Question | Answer |
| Rock cycle | The series of processes that change one type of rock into another type of rock |
| Igneous rocks | A rock that is formed from cooling lava |
| Sedimentary Rocks | A rock that is formed from smaller particles of other rocks |
| Metamorphic rocks | A rock that is formed when it is placed under extreme pressure and heat |
| Sediments | Small, solid pieces of material that comes from rocks or organisms |
| Lava | molten rock that erupts on Earth's surface |
| Extrusive rocks | An igneous rock that turns hard on the surface |
| Intrusive rocks | An igneous rock that turns hard under ground |
| weathering | The breaking down of rocks and other materials on the Earth's surface. |
| Biological weathering | The break down of rocks because of animals or plants |
| physical weathering | when rock is broken down into smaller pieces without a chemical reaction taking place. Using because of heat and cold |
| chemical weathering | The process that breaks down rock through chemical changes |
| Erosion | Processes by which rock, sand, and soil are broken down and carried away |
| Deposition | Process in which sediment is laid down in new locations. |
| Freeze Thaw weathering (frost shattering) | Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. Repeated freezing of ice breaks open rock. |
| Exfoliation (onion skin weathering) | Physical weathering. As the sun shines on rocks during the day it causes them to expand. During the night the rock contracts due to the colder temperature. Over time this continued process causes small pieces of surface rock to flake off. |
| Carbonation | Chemical weathering where rain water is slightly acidic (carbonic acid) and wears away rocks. |
| Cave | A natural underground chamber in a hillside or cliff. |
| Pot hole | A deep hole found in the ground that can open up into a cave |
| Stalagmites | A calcium feature found in a cave rising from the ground |
| Stalagtites | A calcium feature found in a cave coming from the roof. |
| Bedding plane | Layer in the rock of different variety |
| Landform | Natural feature found on land |
