- 3Sedimentary RocksA rock that is formed from smaller particles of other rocks
- 4Metamorphic rocksA rock that is formed when it is placed under extreme pressure and heat
- 5SedimentsSmall, solid pieces of material that comes from rocks or organisms
- 6Lavamolten rock that erupts on Earth's surface
- 7Extrusive rocksAn igneous rock that turns hard on the surface
- 8Intrusive rocksAn igneous rock that turns hard under ground
- 9weatheringThe breaking down of rocks and other materials on the Earth's surface.
- 10Biological weatheringThe break down of rocks because of animals or plants
- 11physical weatheringwhen rock is broken down into smaller pieces without a chemical reaction taking place. Using because of heat and cold
- 12chemical weatheringThe process that breaks down rock through chemical changes
- 13ErosionProcesses by which rock, sand, and soil are broken down and carried away
- 14DepositionProcess in which sediment is laid down in new locations.
- 15Freeze 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.
- 16Exfoliation (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.
- 17CarbonationChemical weathering where rain water is slightly acidic (carbonic acid) and wears away rocks.
