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

salt water
Where is salt water found?
oceans, gulfs and seas. sometimes lakes

Is salt water important?
yes for many reasons
