Ice sheets contain about 99% of the freshwater on Earth, and are sometimes called continental glaciers. There are only two continental glaciers/ice sheets in the entire Earth. One of them being the Antarctic ice sheet. This ice sheet is almost extends close to 5.4 million square miles, and it is has about 7.2 million cubic miles of ice. Ice sheets are formed in areas where snow is unable to melt, so over thousands of years the snow piles up making big pieces of ice. All the snow that keeps layering on compressing on the old layers. Something I found fascinating about ice sheets is that they are moving. The move very slow. It is also melting from the bottom, but even though it is melting it is still increasing in size!!
