| Question | Answer |
|---|---|
| 96.5% of planet Earth's water is what? | salt water |
| What type of system is the water cycle? | closed |
| What powers the water cycle? | the sun's energy |
| What is a watershed? | land that is drained by a water system |
| What is greenhouse effect? | the ability of the atmosphere to keep the planet warm |
| What kind of rock must be on the surface for percolation to occur? | permeable |
| What is an aquifer? | it allows the flow and storage of ground water |
| The water table is found at what boundaries? | the zones of aeration and saturation |
| What is the upper boundary of the zone of saturation called? | the water table |
| What is a divide? | area of higher ground between watersheds |
| What is the water cycle? | process by which water moves through the atmosphere and back to Earth's surface |
| What is a tributary? | a stream that flows into a river |
| What is evaporation? | change of water from oceans and Earth's surface into water vapor |
| What is another name for rain, snow and sleet? | precipitation |
| What is porosity? | the measure of open space between rocks |
| What is condensation? | a change of cooled water vapor into water droplets that form clouds |
| What is permeability? | the measure of whether water can flow through rock |
| What does scarcity mean in connection with water? | That water shortages are occuring |
| What does vulnerable mean in connection with water? | That conditions exist |
| What does stressed mean in connection with water? | Conditions are starting to worsen |
| What does per capita mean? | per person |
| How does per capita relate to water availability? | it is used to decide how much water can be used per person |
| What is a biome? | an environment with similar climates |
| Why should well diggers know where the water table is? | so when the water table drops the well still contains water |
| What are 2 examples of a biome? | a tundra and a grassland |
| What is desalination? | the process of removing salt from ocean water |
| Why is desalination inefficient? | The cost is extremely high |
| What is the downward movement of water through spaces in soil? | percolation |
| What continent has the best water availability? | North America |
| What are the 5 main parts of the water cycle? | condensation, evaporation, precipitation, percolation and run-off |
| What physical factors affect water availability? | location, geography, weather & climate |
| What economic factors affect water availability? | population, density and money |
