Freshwater unit
| Term | Definition |
|---|---|
| Greenhouse effect | Warming of the earth when the atmosphere traps thermal energy from the sun |
| Hydrosphere | is all the water on and below Earth's surface as well as is the atmosphere |
| Groundwater | Water that soaks into the ground, filling up openings in the soil and cracks within the rock, makes up 30% of freshwater |
| Ice/Froze water | Makes up 69% of freshwater |
| Surface water | Still or moving water on the surface of earth; makes up 0.35% of freshwater |
| Atmosphere/ bio water | Water in the atmosphere and water found in living things; makes up 0.65% of freshwater |
| Water cycle | The series of natural processes by which water continually moves throughout the hydrosphere. As water moves through this cycle, it continually changes state |
| Evaporation | Is when liquid water heats up and changes to a gas called water vapor. (the process of a liquid changing into a gas) |
| Water Vapor | Water in a gas form |
| Transpiration | Is the process where water moves through small pores on the leaves of plants and changes to water vapor in the atmosphere |
| Condensation | Occurs when water vapor cools and changes back into liquid water. (the processes of a gas changing into a liquid) |
| Precipitation | Water drops that fall to earth as rain, sleet, snow, or hail |
| Runoff | Water from precipitation that flows over Earths surface |
| Rills | Tiny groves in the soil that have been eroded as runoff moves downhill across the land |
| Gullies | Larger channels of water |
| Streams | Any naturally flowing channel of water |
| Tributaries | Streams or rivers that flow into larger rivers |
| Watershed | The entire area of land that drains runoff into a particular body of water |
| Headwaters | Small streams that form near divides as water journey from the mountains downwards |
| V-shaped valley | Formed when a fast-flowing river erodes steep mountain slopes rapidly |
| Waterfalls | Formed when a flat layer of very hard rock lies over a soft rock that erodes easily |
| Rapid | Super fast flowing water in a river |
| Run | Medium pace flowing water in a river |
| Pool | Slow moving or still water in a river |
| Flood plain | A flat wide area of land around a river that can easily be saturated with water |
| Meanders | Loop like bends in the course of a river |
| Oxbow lake | When a meander is cut off from a river. It resembles a horse-shoe shape |
| Deposition | When water or wind deposits or added dirt/ land to a area |
| Erosion | When water or wind knocks off dirt or smooths an area of land |
| Delta | A build up of land forms when sediment is deposited from a river flowing into an ocean or lake |
| Ponds | Are a smaller and shallower, and sunlight usually reaches to the bottom of all parts of a pond |
| Habitat | Is the place where an organism lives and obtains all things it needs to survive |
| Lakes | Generally deep, still bodies of water, and sunlight does not reach the sandy, pebbly bottom |
| Depressions | Large dips or craters in the land |
| Wetland | An area of land covered with water during al or part of the year |
| Marshes | Grassy wetland areas covered by shallow water |
| Swamps | Like flooded forests, with trees and shrubs comingup out of the water |
