Glaciers are made of snow that has fallen over many years and because it has not moved from the location for so long it has become large solid ice. Glaciers make up 10% of the world’s total land area and they are located in the polar regions like Greenland and Antarctica. [1]

Melting Glaciers

Sea level has been rising little by little over the past century. Part of the sea level rising is due to breaking of icebergs and melting of our world’s land ice. The most important and major ice sheets are Greenland and Antarctica because they contain about 75% of our world’s fresh water. [2]

What happens when they melt?

10% of our land is covered in ice all year around. If that ice were to melt it would end up in the oceans raising its levels. Once pieces of ice break and fall into the water, the heat is transferred to the ice more quickly than it is through air, which makes the ice melt faster. [3]

How do glaciers move?

Glaciers known as “rivers of ice,” actually move. The cause of the motion of glaciers is gravity. A glacier molds itself to the land and also sculpts the land as it slides down the valley. Glaciers slide on their beds, which makes them able to move faster. Clearly, if a glacier looses more than it gains it will soon turn into water. [4]

Why does this matter?

Reducing the amount of things like gasoline for cars and coal burned for electricity can help slow the melting process of the ice. If the sea level rises due to the melting of glaciers it will affect us humans. Weather it is by creating natural storms or overflowing our neighborhoods with water. NASA’s research has shown that by 2050 about $66 - $106 billion worth of property is probable to sit below sea level. [5]
