| Question | Answer |
|---|---|
| erosion | the movement of sediment by forces such as wind, water and ice (WED > WWI) (WEDCC/Sedimentary Rock) |
| deposition | The deposit of sediment in a new location. (WED > WWI) |
| weathering | the breaking down of rock into pieces of sediment (WED > WWI) |
| nonrenewable | a natural resource that cannot be replaced in a short time (FF=CON) |
| renewable | a natural resource that can be replaced in a short amount of time (example: solar panels and wind turbines for energy) |
| fossil fuels | Nonrenewable resources: coal, oil and natural gas (FF=CON) |
| coal | a fossil fuel in solid form, made from the remains of plants and animals in ancient swamps and forests |
| oil | a fossil in liquid form made from the remains of marine animals and plants |
| sedimentary rock | Type of rock formed from the compaction and cementation of sediment |
| compaction | step in the formation of sedimentary rock where the sediment is pressed together |
| canyon | A landform that is built up at the mouth of a river as sediment is deposited. V-shaped |
| delta | (river delta) a landform that is built up at the mouth of a river as sediment is deposited |
| sand dune | a landform formed when wind deposits sand to a new location |
| cliff | formed by waves crashing against rock over a long period of time |
| wide valley | U-shaped. Formed by a glacier moving slowly over the land |
| mesa | formed by rain and wind weathering away sediments from a rock in the desert |
| rotate | to spin on an axis axis- the imaginary line through which the Earth rotates or spins rotation (ro-day-tion) - Earth rotates on its tilted axis, an imaginary line from the North to South Pole, completing one full spin every 24 hours (one day). |
| revolve | to move around another object (seasons) Earth's revolution is its ~365 day orbit around the Sun, defining a year and causing seasons due to the tilt of its axis |
| orbit | the imaginary path an object takes as it revolves around another object |
| axis | the imaginary line through which the Earth rotates or spins |
| Sun | the center of the solar system. The Earth rotates around the sun. |
| Moon | Earth's natural satellite. A satellite is an object that moves around a larger object. The moon is like a satellite because it moves around Earth. |
| Mars | the 4th planet from the sun. (My Very Evil Mother Just Swatted Uncle's Noes) Mercury Venus Earth Mars jJupiter Saturn Uranus Neptune |
| East | The direction the sun rises each day |
| atmosphere | Layer of gases surrounding the Earth |
| gravity | forces that keep planets revolving around the sun. It is the force that draws objects to the center. |
| craters | crated on the surface of the moon and Earth from the impact of meteorites |
