water that has very little salt (almost none)
huge sheet of moving ice
underground supply of water
what is water important to?
environment, plants and animals
most animals and plants need fresh water to live, why is this a problem?
not much of the Earth's water is fresh
almost all of the freshwater on Earth is found where?
glaciers in Antarctica
where can freshwater be found?
glaciers, rain, melted snow, groundwater
what is groundwater?
water that is found underground
Why is groundwater important?
people use groundwater to supply their homes with water
What type of water is most of the Earth covered with?
Where is salt water found?
oceans, gulfs and seas. sometimes lakes
What lake has salt water?
Great Salt Lake
Is salt water important?
yes for many reasons
the process of a gas turning into a liquid
change from a liquid to a gas
rain, sleet, snow or hail
water moving from Earth's land, through rivers toward the ocean, to the air and then back again
solid water is ...
water in the gas form is called...
What does the state of water depends on?
water at room temperature
Water when it gets cold
freezes into ice
when water gets hot enough
turns to water vapor (a gas)
water vapor (gas) loses thermal energy it becomes....
when water changes from its gas state to a liquid state
air around Earth
gas that people need to live
what is happening in the atmosphere at a certain place and time
measure of how hot or cold something is
measures wind speed
weather depends on...
where a place is
what is used in predicting weather
what are weather instruments
thermometers, anemometers, weather satellites
Sun's rays warm Earth's land and water causing water to...
evaporate and rise
when ice gains thermal energy
changing state of water to liquid water
What are glaciers made of?
