What percentage of the Earth’s water is fresh water? | 3% |
What is the gaseous form of water? | Water Vapor |
What percentage of fresh water is in the form of icebergs? | 75% or Three quarters |
Most fresh water in the atmosphere is the in the form of what? | Water Vapor |
What percent of fresh water on earth is usable by humans? | 1% |
Some of Earth’s fresh water is deep what? | Groundwater |
True or False. All Earth’s oceans are connected to form a single world ocean? | True |
Icebergs are formed from frozen what? | Fresh water |
Where is most fresh water located: underground water OR River and Lake water? | Underground water |
True or False. The Water Cycle is unnatural and a manmade process? | False.
The Water cycle is a natural process. |
What is the water cycle powered by? | The sun. |
True or False. The water cycle has no real beginning or end. | True. |
How do plants take in water? | Through their roots. |
How do plants give off water? | Through transpiration in their leaves. |
What are the major processes of Water Cycle? | Evaporation, Condensation, and Precipitation. |
What does Evaporation change water to? | Water Vapor |
What produces water vapor from plants? | Transpiration. |
What forms clouds from water vapor? | Condensed water droplets that combine with dust particles in the atmosphere. |
Precipitation falls back to the earth in what forms? | Rain, snow, sleet, and hail. |
Why does water vapor condense (condensation) when it travels far above the earth? | Higher up, air tends to be colder.
Cold air holds less water vapor than warm air. It condenses into liquid water. |
How do clouds form? | Condensed droplets of water clump together around tiny dust particles forming clouds. |
If groundwater reaches the surface, how does it reenter the water cycle? | It reenters the water cycle by evaporation into the earth’s atmosphere. |
What is the source of all fresh water on the earth’s atmosphere? In other words, where does all fresh water come from? | Precipitation. |
True or False. The rates of evaporation and precipitation are the same and balanced. | True. |
What are some ways that people use water? | Home use, Agriculture, Industry, Transportation, and Recreation. |
Some areas of agriculture do not receive adequate amounts of rainfall. What do the do to solve the problem? | Irrigate (irrigation) water to supply water to farm land. |
How is water essential to living things? | Water is essential to living things to grow, reproduce, and carry out other important processes. |
Why are icebergs considered the “terror of ships at sea? | Because can cause great damage to ships including sinking them like the Titanic. |
What do icebergs consist of? | Fresh Water. |
How do icebergs form? | When glaciers reach the sea coast, large chunks break off forming icebergs. |
How are icebergs tracked? | They are tracked by using ships, planes, and satellite. |
Why is it important to track icebergs? | To warn ships and other watercraft of icebergs to prevent accidents. |
