Term | Definition |
---|---|
Evaporation | The process by which water changes from a liquid to gas and energy is gained. |
Transpiration | The process by which plants release water vapor through their leaves. |
Condensation | The process by which water changes from a gas to a liquid and energy is lost. |
Precipitation | Forms of water such as rain, snow, sleet, or hail that fall from clouds and reach Earth's surface. |
Run Off | Water that flows over the ground surface rather than soaking in the ground. |
Groundwater | Water that fills the cracks and pores in underground soil and rock layers. |
Permeable | The ability of rock or sediment to let fluids pass through its open spaces, or pores. |
Impermeable | Describes something that does not allow water to pass through. |
Pores | Tiny openings in and between particles of rock and soil that may contain air or water. |
Aquifer | Any underground layer of rock that holds water. |
Water Table | Top of the saturated zone(tells you how deep to dig in order to reach water). |
Saturated Zone | Area totally filled with water(this is where groundwater is found). |
Watershed | The area of land that is drained by a river system. |
Drought | A long period when rainfall is less than average. |
Water Conservation | Is the most cost-effective and environmentally sound way to reduce our demand for water. |
Salinity | A measure of the amount of dissolved salts in a given amount of liquid. |
Coriolis Effect | The curving of the path of a moving object from an otherwise straight path due to the Earth's rotation. |
Spring Tide | A tide of increased range that occurs two times a month, at the new and full moons. |
Neap Tide | A tide of minimum range that occurs during the first and third quarters of the moon. |
Crest | The highest point of a wave. |
Trough | The lowest point of a wave. |
Wavelength | The distance from any point on a wave to an identical point on the next wave. |
Wave height | The vertical distance from the crest of a wave to the trough. |
Wave frequency | The frequency of a wave is the number of waves passing a point in certain time. |
Continental Shelf | The gently sloping section of the continental margin located between the shoreline and the continental slope. |
Continental Slope | The steeply inclined section of the continental. Margin located between the continental rise and the continental shelf. |
Abyssal Plain | A large, flat, almost level area of the deep-ocean basin. |
Seamount | A submerged mountain on the ocean floor that is at least 1,000m high and that has a volcanic origin. |
Volcanic Island | Seamounts that come above the ocean surface. |
Trench | A deep canyon in the ocean floor. |
Mid-Ocean Ridge | The undersea mountain chain where new ocean floor is produced; a divergent plate boundary. |
