| Term | Definition |
|---|
| Model | a represention of an object or process(i.e) globe |
| Erosion | the process where by earth materials are worn away by |
| Canyon | a V-shaped valley eroded by a river |
| Delta | afan -shaped desposit at the mouth of a river |
| Plateau | nearly level area that has been uplifted |
| Deposition | the process by which eroded earth materials settle out in a place another |
| Meander | a curve or loop in a river |
| Mountain | high , uplifted area with steep slopes |
| Floodplain | the often flat land on either side of a river which is covered by water when the river floods |
| Soil erosion | The wearing away of land by rainfall, river current , ocean tide , or wind. |
| River | The main drain and mover of water in a watershed . Like the vein in a steak platter |
| Watershed | All the land around a river that collects water for that river; the water is a "shed" area into the river. The name of which catches its water |
| Marsh or swamp | Tract of low,wet,soft land. Marshes and swaps act as giant sponges, absorbing tons of water in times of flood and releasing water slowly in times of drought; act as filters, cleaning the pollution from the river;and acts as important habitats and breeding places for plants and animals |
| Estuary | Where salt and fresh water meet. usually at the mouth of a river , where it emties into the sea ( Norwalk river meets Long Island Sound at Norwalk Harbor) |
| Valley | A low area between hills and mountains often where ruvers flow |
| Water table | The top of the ground water supply During wet periods water can be seen above the ground in many places, such as s swampy spot . In dry periods man must often dig to find the water table |
| Glacier | Large mass of ice and snow which is formed faster that it can melt and moves down the mountains as it grows. Glaciers dug out watersheds and rivers beds by scratching, planning and polishing the land as they moved back and forth |
| Triibutary | a small stream which runs into the main river |
| Culvert | a tube used to control, contain or straighten a stream of water |
| Community | A group of plants and animals that live in the same area and are dependent on one another for food and other requirements |
| Succession | A natural process of change in an environment. For example , a pond may gradually change into a marsh and then a meadow . a meadow may change into a forest . Forests may also show succession with one tree group changing to another |
| Vegetation | all the plants and trees in an area |
| slope | an elevated geological formation |
| Basin | a natural depression in the surface of the land often with a lake at the bottom of it |
| Elevation | the event of something being raised upward |
| Channel | a deep and relatively narrow body of water (as in a river or a harbor or a strait linking two larger bodies) that allows the best passage for vessels |
| Sediments | small pieces of rock, soil, and other materials |
| What happens when water flows over earth maerials ( Erosion ) | Pick up , move ,drop off is what happens when water flows over earth material |
| The water source (mountain) formed a ( Erosion ) | Lake |
| The water flowed down forming a ( Erosion ) | Waterfall on the plateau |
| The plateau/waterfall further erdded creating 2 | a river , then produced a canyon |
| The V shaped canyon was | Deep |
| What happens to the eath materials eroded by water (Deposition) | The earth the marterials eroded into a Delta, Clay, Sand , Canyon and a River |
| How does the size of particle affect depostion | The small the particle is the futher it with travel because its lighter for example (Clay) |
| How does the slope of the stream table affect erosion and deposition (Slope) | Because the water flows faster , this makes the canyon deeper and wider there is more erosion so it makes a bigger delta as it deposits the sediments |
| what makes the grand canyon such a famous place | It strechs for 443 kilometers (227 miles) along the Colorado river in Arizona |
| John Wesley Powell | explorer and geologist |
| What made John Wesley Famous | Led the first successful expedition in the Grand Canyon |
| When land is polluted, what happens to the pollution when water flows over the land | It affects it in a major way because the it gets picked up throught the river and gets droped off in the Delta |
| To increase the amount of erosion and deposition | add water |
| flood | too much water in a specific area |
| how does vegetation help prevent erosion | by holding earth materials back and slows erosion down |
