| sedimentary rock | rock that form when sediment or the remains of |
| igneous rock | rock that forms when molten rock cools and |
| metamorphic rock | rock that forms when other rocks change because |
| types(s) of igneous rock | pumice |
| type(s) of sedimentary rock | limestone and sandstone |
| type(s) of metamorphic rock | quartzite and slate |
| the hardest kind of rock | metamorphic rock |
| mechanical weathering | the mechanical breakdown of rocks and |
| chemical weathering | the chemical breakdown of rocks and minerals. |
| biological weathering | the breakdown of rocks and minerals by |
| ice wedging | when water gets trapped within rocks or in rock cracks and the temperature changes over time |
| exfoliation | As weather and erosion strip away the surface of the earth, there is less weight on the buried rock. This makes the rock expand and break off |
| dissolution | Some rocks and minerals are easily dissolved when they come in contact with acidic water |
| oxidation | Occurs when the iron in minerals meets with the oxygen in |
| minerals | the basic ingredients of rock. They form as crystals, |
| texture | describes soil types depending on how much sand, silt, or clay |
| bedrock | the solid unweathered layer of rock beneath the earth’s |
| causes of mechanical weathering | abrasion, ice wedging, exfoliation |
| causes of chemical weathering | dissolution, oxidation |
| causes of biological weathering | plants, animals, humans |
| constructive wave | small and slow winter waves that build a beach |
| destructive wave | tall adn frequent summer waves that cause erosion |
| seawall & breakwater | structures built to protect houses and hotels on the shoreline from storms |
| barrier islands | along the seashore, wind and water work together to deposit sand and build these islands |
