| Definition | Term |
|---|---|
| rock made by the deposits of sediments that form layers | Sedimentary Rock |
| particles of matter could be sand, silt, shell and other substances that are carried then deposited | Sediment |
| the wearing away of sediments by water, waves, wind, or ice | Weathering |
| the moving or carrying away of sediments to a new location | Erosion |
| the dropping of sediments to a new location | Deposition |
| the pressure of pressing together sediments | Compaction |
| sticking together like glue | Cementation |
| the upper layer of Earth consisting of a mixture of organic remains, rocks, and clay particles | Soil |
| rocks, air, and water | Components of Soil |
| all soil contains mineral particles, sand, silt, shells, and clay particles; also organic matter, water, and air | Properties of Soil |
| very small in size, tiny, a speck, crumb | Particle |
| tiny particles of broken down rock, about the size of salt, very little water stays, loses water, no nutrients | Sand |
| finer and softer sand, like flour, silky smooth, slippery when wet, some water stays, some nutrients, but erodes easily | Silt |
| a sticky when wet, fine grained soil that does not allow water to flow through easily | Clay |
| smaller stones, pebbles of rock, no water stays, no nutrients | Gravel |
| the best soil of all because it's a mixture of humus, clay, and sand | Loam |
| below the humus, and is where the seeds will germinate | Topsoil |
| to keep in or hold back | Retain |
| when something that is dead goes through a chemical process and it breaks down into the soil, making it richer | Decomposition |
| to go through decomposition | Decay |
| an area of land, or land shape found on the surface of the Earth | Landform |
| a huge V-shaped valley made from moving water | Canyon |
| a mound of sand deposited by wind | Sand Dune |
| created by the deposition of sediment; large flat area of land at the mouth of a river | Delta |
| formed by wind picking up sediment and blasting or blowing a hole in the rock | Desert Arch |
| a huge moving body of ice that scrapes the landscape | Glacier |
| a low area of land between hills or mountains | Valley |
| made by moving water | V-shaped Valley |
| made by a glacier scraping through | U-shaped Valley |
| when the temperature drops to 0 degrees Celsius | Freezing |
| becomes a liquid by heat | Melting |
| becomes softer by warming | Thawing |
| a mountain built up from hardened lava, rocks, and ash that erupted out of Earth | Volcano |
| when a volcano becomes active and erupts ash | Erupt |
| a shaking of Earth's crust caused by rock slabs moving against each other deep below Earth's crust | Earthquake |
| the sudden downhill movement of a huge mass of rock, soil, and mud | Landslide |
| a fuel that formed from the decayed remains of ancient animals and plants | Fossil Fuels |
| made from crops and can be used as an alternative resource like ethanol for cars | Biofuels |
| to go through decomposition | Decay |
| a continuous force against something | Pressure |
| resources that CAN be replaced in a short amount of time | Renewable Resources |
| resources that CANNOT be replaced quickly | Nonrenewable Resources |
| the wise use and protection of natural resources | Conservation |
| converting waste into reusable materials | Recycle |
