Earth's Changes
Sedimentary Rock, Landforms, Natural Resources
| Question | Answer |
|---|---|
| Cementation | natural GLUE where tiny bits of rock, sand, and mud (sediments) get stuck together to form solid rock, like sandstone, when dissolved minerals in water crystallize and fill the spaces between the grains, acting as a natural cement to bind them |
| Compaction | happens when sediments are deeply BURIED, placing them under PRESSURE because of the weight of overlying layers |
| Weathering | the breaking down of rock into smaller pieces called sediment |
| Erosion | the movement of sediment from one place to another |
| Deposition | dropping off of sediment in a new location |
| Fossil Fuel | nonrenewable energy resources found deep in the Earth's crust between layers of sedimentary rock; oil, natural gas, and coal |
| Coal | solid nonrenewable fuel source found in sedimentary rock; formed from the remains of ANCIENT PLANTS in SWAMPY regions |
| Oil (Petroleum) and Natural Gas | nonrenewable fuel sources found in sedimentary rock; formed from the remains of MICROORGANISMS found in ANCIENT SEAS |
| Sediments | tiny bits of dirt, sand, pebbles, shells, and even dead plants or animals that get carried by wind, water, or ice |
| Sedimentary Rocks | like Earth's layered sandwiches, made from tiny bits of old rocks, shells, and plants (called sediments) that get squeezed and stuck together over millions of years; often where fossils are found |
| Sand Dune | a large hill of sand formed by wind deposition |
| U-Shaped Valley | a wide, flat valley that was formed by slow moving glaciers that scraped and carved by weathering and eroding the rock into a U shape |
| Delta | a triangular fan of land that forms when a river carrying sand, mud, and rocks (called sediment) slows down and drops (deposition) it all at its mouth where it meets a bigger, calmer body of water like an ocean or lake |
| V-Shaped Canyon | a deep valley with steep sides, shaped like a V, carved into the Earth's surface by river weathering and erosion |
| Frost Wedging | when water gets into tiny cracks in rocks, freezes, and expands like a wedge, pushing the rock apart until it breaks |
| Glacier | large masses of frozen ice that move slowly downhill; as glaciers move, they wear away the surrounding land through erosion |
| Landform | a natural shape on the Earth's surface, like mountains, hills, valleys, or plains, formed by natural forces like water, wind, and ice wearing away or building up the land |
| Biofuel | a special kind of fuel made from plants, animal waste, or other living things (like corn, sugarcane, algae, or even used cooking oil) |
| Conservation | the protection of things found in nature; preserve natural resources so they will still be around in the future |
| Nonrenewable | materials from nature that CANNOT be replaced because they take millions of years to replenish - oil, natural gas and coal |
| Pollution | making the Earth, air, water, or land dirty and unhealthy with harmful things like trash, chemicals, or smoke, which can make people, animals, and plants sick |
| Recycle | taking used items like paper, plastic, and glass, and turning them into new products instead of just throwing them away as trash |
| Reduce | to make something smaller or use less, resulting in a smaller amount of waste (trash) |
| Renewable | Materials from nature that are replaced very quickly - for example: air, plants, animals, sunlight, and water |
| Replenish | to make complete or full again; refill |
| Reuse | using something more than once or finding a new way to use it instead of throwing it away |
| Resource | anything useful that helps people get what they need or want, like things from nature (water, trees) |
| Agents of Change | Wind, water, and ice |
| Earthquake | the sudden shaking of the Earth's surface caused by a rapid release of energy in the planet's crust because giant puzzle pieces called tectonic plates beneath our feet shift, bump, or slide against each other |
| Erupt | to burst out suddenly and powerfully, like a volcano shooting out lava |
| Flood | when a huge amount of water overflows and covers land that's usually dry, like streets or yards |
| Landslide | when a big chunk of earth, rocks, mud, and trees slides down a hill or mountain; gravity pulls everything down; usually triggered by heavy rain making the ground too heavy |
| Magma | super hot, melted rock found deep underground |
| Lava | super hot, melted rock that comes out of a volcano when it erupts |
| Volcano | a mountain with a hole that lets out hot, melted rock (lava), ash, and gas from deep inside the Earth when it erupts |
| Rapid Changes to the Earth | Earthquakes, volcanic eruptions, landslides |
| Slow Changes to the Earth | Weathering, erosion, and deposition |
| Natural Resources | Anything from nature that we can use to improve our lives |
