Beginning Earth Science
| Definition | Term |
|---|---|
| The breaking down of rock by water, wind, or ice. | Weathering |
| The moving or carrying of sediments to a new location. | Erosion |
| The dropping of sediments in a new location. | Deposition |
| Sticking together like glue. | Cementation |
| The pressing together of sediments. | Compaction |
| Rock made by the deposits of sediments that form layers. This kind of rock is where most fossils are found. | Sedimentary Rock |
| Particles of matter could be sand, silt, shell, and other substances. | Sediment |
| Created by the deposition of sediment by water. Streams and rivers deposit sediments at the mouth of a river. They are the large flat areas of land at the mouth of a river. | Deltas |
| A mound of sand deposited by wind. | Sand Dune |
| Made by a glacier scraping through. | U-Shaped Valley |
| Made by moving water. | V-Shaped Valley |
| A huge, moving body of ice. | Glacier |
| When something that is dead goes through a chemical process that breaks it down into the soil making the soil better. | Decomposition |
| A circuit that has more than 1 path for the electricity to take. | Parallel Circuit |
| A circuit that has only 1 path for the electricity to take. | Series Circuit |
| Evidence of the past. | Fossils |
| Fuels formed from the remains of prehistoric animals and plants that were buried in layers of rock and subjected to large amounts of heat and pressure. | Fossil Fuels |
| Resources that can be replaced in a short amount of time. | Renewable Resources |
| Resources that cannot be replaced quickly. | Nonrenewable Resources |
| Made from crops and can be used as an alternative resource like ethanol for cars. | Biofuels |
| The wise use and protection of natural resources. | Conservation |
| Converting waste into reusable materials. | Recycle |
| Tool that measures the wind speed. | Anemometer |
| Rain, snow, sleet, or hail | Precipitation |
| The gradual gathering of precipitation. | Accumulation |
| Water held underground in the Earth. | Ground Water |
| Energy from the Sun | Solar Energy |
| The process by which water is constantly moved around the Earth. | Water Cycle |
| Plants giving off water vapor. | Transpiration |
| Water being carried away across the surface of the Earth. | Runoff |
| To spin on an axis. | Rotation |
| To go all the way around something else. | Revolution |
| The path something takes as it revolves around something else. | Orbit |
| An imaginary line dividing the Northern and Southern hemispheres. | Equator |
| A sloping position. | Tilt |
| This is caused by the Earth's rotation. | Day/Night Cycle |
| These are formed by light being blocked by an object. They will be longest in the early morning/late afternoon and shortest around noon. | Shadows |
| The direction the Sun rises in. | East |
| The direction the Sun sets in. | West |
| Caused by the tilt of the Earth and our orbit around the Sun. | Seasons |
| These are caused by the gravitational pull of the Moon. | Tides |
| How long it takes the Earth to rotate 1 time. | 24 hours/ 1 day |
| How long it takes the Earth to revolve around the Sun one time. | 365 days/ 1 year |
| The order of the planets. | Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune |
| This is about how long it takes the Moon to orbit the Earth one time. | 28 days |
