Water Cycle

QuestionAnswer
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
