Test for Module 5
Apologia Physical Science test #5
| Question | Answer |
|---|---|
| Transpiration | Emission of water vapor from plants. |
| Condensation | The process by which water vapor turns into liquid water. |
| Residence Time | The average time a given molecule of water will stay in a given water source. |
| Percolation | The process by which water passes from above the water table to below it. |
| Adiabatic cooling | The cooling of a gas that happens when a gas expands. |
| Where does the majority of Earth's water reside? | in the oceans |
| What is the largest source of liquid freshwater on the planet? | groundwater |
| What water source is a molecule of water in once it has gone through transpiration? | it is in the atmosphere. |
| Water was in the ocean and is now a cloud. What two hydrologic cycle processes happened in order to make that transfer? | Evaporation allowed it to leave the ocean and condensation put it in the cloud. |
| Where is the residence time longer, in the ocean or in the fast moving stream? | In the ocean |
| If a lake has no means of getting rid of water except evaporation, does it contain saltwater or freshwater? | it contains saltwater |
| What do the oceans tell us about the age of the earth? | They tell us that the earth's age can't be a billion years old, they would be much saltier if they were over a million years old! |
| An enormous amount of ocean water in the polar region freezes, Does it form an iceberg? Why? Or why not? | It does not, Icebergs are freshwater and come from glaciers, Sea ice has salt mixed in with it. |
| What process in the hydrologic cycle is responsible for making glaciers? | precipitation, glaciers start because of snow, snow is precipitation |
| what causes the condensation that makes most clouds? | adiabatic cooling |
| If a sample of gas is compressed and nothing else is allowed to change, what will happen to the temperature of the gas? | The temperature will increase |
| if there is a lot more rain than normal in an area over a long period of time what happens to the depth of the water table? | The depth will decrease |
| Why is groundwater pollution so hard to trace back to its original source? | because of the way it flows |
