Water Cycle
Question | Answer |
---|---|
What are the three MAIN processes/stages of the water cycle? | evaporation, condensation, precipitation |
During evaporation a liquid changes into... | a gas |
Heat from the sun makes water evaporate into a gas called? | water vapor |
What happens during condensation? | a gas turns into a liquid |
What are examples of precipitation? | Rain, snow, sleet, and hail. |
When the sun heats the Earth, water in the ocean and on land... | evaporates |
What are clouds made of? | tiny drops of liquid water |
Where does the energy come from in order for the water cycle to work? | sun |
Another word for vapor is... | gas |
The tiny drops of water in clouds bump into each and grow bigger. When they get too big and heavy, they start falling. This is... | precipitation |
A solid changing directly to a gas is called.... | sublimation |
What is the gaseous form of water? | Water Vapor |
A gas changing directly to a solid is called... | deposition |
Most fresh water in the atmosphere is the in the form of what? | Water Vapor - or a gas. Same thing. |
What percent of fresh water on earth is available to humans? | Less than 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 available 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. |
Water vapor must have a solid substance to _________________ . | condense |
How do plants give off water? | Through transpiration in their leaves. |
What is the reverse process to sublimation? | Deposition. This happens when it is cold. Most frost is formed by deposition. |
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. These "dust particles" can sometime be acidic and or "bad" and cause the rain to be acidic and "bad". |
Do clouds form because of cohesion? | Not sure. Just thought about it while typing. We should look that up! |
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. |
How does groundwater reenter the water cycle? | It reenters the water cycle by evaporation into the earth's atmosphere when it returns to the surface. This can take thousands of years or just a few months. |
What is the source of all fresh water on the earth? 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, 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. |
How is most fresh water used by humans? | Agriculture/Farming |
What do icebergs consist of? | Fresh Water. |
How do icebergs form? | When glaciers reach the sea coast, large chunks break off forming icebergs. This is called calving |
List three ways water in the water cycle becomes water vapor. | evaporation, sublimation and transpiration |
Can you see water vapor? | NO. |
Which 3 water cycle processes release energy? | freezing, deposition, condensation |
Which 3 water cycle processes absorb energy? | melting, sublimation, evaporation |
Heat equals ... | energy |
Is ice melting is an example of matter gaining or losing energy? | gaining |
Water can be stored underground. This water can be called... | ground water or an aquifer |
The top of of an aquifer or ground water is called the | water table. |
As ground water is removed or slowly flows downhill the _________________ gets lower. | water table |
As ground water is added by an increase in percolation and infiltration the _________________ gets higher. | water table |
A liquid evaporating is an example of matter gaining/losing energy from the environment. | gaining |
-Choose One- A liquid freezing is an example of matter (gaining/losing) energy to the environment. | losing |
Any water that has traveled under ground is now called... | ground water. |
Does frozen really mean cold? | No. -Frozen means to be in the solid state of matter. |
Are all solids frozen? | Yes. |
What are the 3 common states of matter? And the 2 uncommon ones? | BEC - Solid - Liquid - Gas - Plasma |
What percentage of the Earth's water is fresh water? | 3% |
What percentage of fresh water is in the form of icebergs? | Over 66% or more than 2/3s |
Where does over 99% of energy on Earth come from? | The sun |
Where does less than 1% of energy on Earth come from? | The radioactive decay of elements in the core |
When a liquid boils, is it always "HOT"? | No -Oxygen boils at -183 degrees Celsius and nitrogen Boils at -195.8 degrees Celsius |
An area of land that causes run-off to go one way or another is called a ____________________. | Divide |
The water cycle is driven by 2 factors. The 1st is the energy from the sun and the 2nd is _____________________. | gravity |
