One question people may want to know about glaciers is, how much fresh water, that the glaciers hold, Well, the earth itself holds Approximately 326 million cubic miles of fresh water. Which is enough to fill the United States with a lake 90 miles deep. 72% of water is on surface area of the Earth, 97% of it is in oceans is salt water which is not drinkable. Frozen water is 9% lighter than water, which is the reason ice floats on water.Of all earths water, only about 2.5% of it is fresh water. The only amount that is accessible is 0.01%.
Fun Fact
Alaska is estimated to have more than 100,000 glaciers. Most remain unnamed!!!
This is a image of a Freshwater Glacier.
Some Facts about Freshwater on Earth
Ok, would you like to know some facts about the earths fresh water? Well, you should know what 70% of the freshwater on earth is locked in ice caps. Causing it to be very hard to retrieve. 1/3 of the worlds population suffers from water scarcity. Less then 1% of the worlds fresh water is already accessible though. Only 6 Countries have 50% of Fresh Water reserves which are the Countries of Brazil, Russie, Canada, Indonesia, China, and Columbia. A Huge problem maybe that 75% of the earths freshwater is also held in glaciers and polar ice-caps. Well the other 21% is held in Great Lakes Basin.
How much Fresh Water Much Do Humans Need?
Humans infact do use and need Freshwater, It is said that fresh water is a very scarce cupply, but is amazingly excellent drinking water. Fresh water is also healthy towards and for humans. Many people who live near glaciers use its freshwater as there drinking water. So when the Glaciers melt, the water goes and melts into the salt water, contaminating the Freshwater, making it not drinkable.
These Glaciers have either moved or melted. For some other areas water has been freezing were it does not normally form.
Shows the plates of the Earth and how the Glaciers could be in danger if a huge Earthquake happened.
