Unit 4- Water
6th Grade Unit 4- Part 1
| Question | Answer |
|---|---|
| Atmosphere | The layer of gases surrounding Earth, which includes the air we breathe. |
| Tributaries | Smaller rivers or streams that flow into a larger river or body of water. |
| Runoff | Water from rain or melted snow that flows over the ground and into rivers, lakes, or oceans. |
| Salinity | The amount of salt in water. |
| Equatorial | Related to the area around the Earth's equator, where it is usually warm. |
| Groundwater | Water that is stored underground in soil or rock. |
| Brackish | Water that is saltier than freshwater but less salty than seawater, often found where rivers meet the sea. |
| Estuary | A place where freshwater from rivers meets and mixes with saltwater from the ocean. |
| Infiltration | The process of water soaking into the ground. |
| Condensation | The process of water vapor cooling and changing into liquid water, like when clouds form. |
| Precipitation | Water that falls from the sky in forms like rain, snow, sleet, or hail. |
| Evaporation | The process of liquid water changing into water vapor (gas) and rising into the air. |
| Transpiration | The release of water vapor into the air from plants and trees. |
| Density | How much mass is in a certain amount of space; for example, saltwater is denser than freshwater. |
| Aquifers | Layers of rock or sediment underground that hold water. |
| Fresh Water | Water that is not salty, found in rivers, lakes, and most groundwater. |
| Glaciers | Huge, slow-moving masses of ice found in cold regions or on mountains. |
| Groundwater | Water found under the Earth's surface. |
| Lakes | Large bodies of freshwater surrounded by land. |
| Oceans | Large bodies of saltwater covering most of the Earth's surface. |
| Rivers | Large, flowing bodies of water that usually flow into an ocean, lake, or another river. |
| Salt Water | Water that contains a lot of salt, like the water in oceans and seas. |
| Swamps | Wet, marshy areas where water collects, often with trees and plants that can grow in water. |
| Water Cycle | The movement of water through the environment, changing from liquid to vapor to solid and back again. |
| Continental Shelf | The edge of a continent that is underwater and extends into the ocean. |
| Continental Slope | The steep slope where the continental shelf drops off into the deep ocean. |
| Continental Rise | The area at the bottom of the continental slope where it starts to flatten out before reaching the deep ocean floor. |
| Abyssal Plain | Flat, deep parts of the ocean floor. |
| Deep Ocean Floor | The bottom layer of the ocean, far from land, and very deep. |
| Mid-Ocean Ridge | Underwater mountain ranges found in the middle of oceans, where tectonic plates move apart. |
| Oceanic Trench | Deep, narrow valleys in the ocean floor, usually near the edges of tectonic plates. |
| Seamount | An underwater mountain that rises from the ocean floor but doesn’t reach the surface. |
| Coriolis Effect | The way Earth's rotation causes moving air and water to turn and swirl rather than moving in a straight line. |
| Deep Ocean Current | Slow-moving currents in the ocean that happen deep below the surface, often driven by differences in water temperature and salinity. |
| Surface Current | Ocean currents near the surface, usually caused by winds. |
| Tide | The rise and fall of sea levels caused by the gravitational pull of the moon and the sun on Earth's oceans. |
| Waves | Movements on the surface of the ocean caused by wind, earthquakes, or other forces. |
