Water Cycle
| Question | Answer |
|---|---|
| Water Cycle | The movement of water from the ocean (evaporation), to the atmosphere (condensation) to the land (precipitation) and back to the land (run off, ground water, transpiration); the water cycle is powered by the sun |
| Nonpoint-source pollution | Pollution where there is no one specific cause (i.e. oil that runs off from roads) |
| Evaporation | The change of water from liquid to gas (sun heats the ocean water) |
| Precipitation | Water drops become heavy enough to fall back to Earth. Example: rain, sleet, snow, hail. |
| Condensation | Change of water vapor (gas) back to liquid in the atmosphere (caused by cooling) |
| Transpiration | The release of water vapor from a plant’s leaves |
| Currents | The movement of ocean water in a regular pattern; can be warm or cold depending on location |
| Waves | Energy created by wind that travels through the ocean water creating crests and troughs. |
| Gulf Stream | A warm water current in the Gulf of Mexico and Atlantic Ocean that creates warmer than normal climates for Britain and Iceland |
| What are the stages of the water cycle and how are they related? | Evaporation, Condensation, Precipitation, Ground Water of Run Off, Transpiration The stages lead water from the ocean to the atmosphere to the land and back to the ocean. This supplies Earth with a never ending source of fresh water. |
| High Tides | when the moon’s gravity pulls Earth’s water in a bulge. |
| Low Tides | water drawn away from areas by moon’s gravity |
| Neap Tide | minimal tidal range during the first and last quarter moons occurs when the moon and the sun are at right angles. |
| Spring Tide | usually high and low tides during the new and full moons. |
| Point-source pollution | Pollution with one specific cause (i.e. oil tanker spill) |
| Continental Shelf | from the shore to the slope |
| Continental slope | from the edge of the shelf to the abyssal plain |
| Abyssal plain | flat ocean basin |
| Mid-ocean ridges | the mountain range formed at the divergent boundary and created by rising and cooling magma. |
| Seamounts | undersea volcanic mountains. |
| Trenches | where subduction occurs; deepest part of the ocean basin. |
| Explain the impact ocean currents (i.e. the Gulf Stream current) have on climate. | Currents can make areas have a cooler than expected climate (cold currents) or warmer than expected climate (warm currents) because ocean currents can change the atmosphere above the water. |
| What two major elements make up most of the dissolved solids in the ocean? | Sodium and chlorine (sodium chloride = salt) |
| When do Spring tides and Neap tides occur? . | Spring tides occur when the sun, Earth and moon are aligned (full and new moon phases); Neap tides occur when the sun, Earth, and moon create a right angle (first and last quarter moons). |
| What are the parts of a wave? | |
| What causes tides? | Tides are caused mainly by the pull of the moon’s gravity on the water. The sun’s gravity also assists in causing tides. |
| What is the Coriolis Effect? | The curving of the path of an object due to Earth’s rotation. Ocean currents are curved due to the Coriolis effect. |
| How often do high tides and low tides occur? If a high tide occurs at 12:00 noon on Friday, what time will the high tide occur Saturday? | Tides occur twice per day (2 high tides and 2 low tides). They occur about 12 hours and 25 minutes apart. A high tide on Friday at 12:00 noon will result in a high tide on Saturday at 12:50 PM (24 hours and 50 minutes apart). |
