Glaciers <<GLAY shuhrz>> are giant areas of ice that circulate slowly over land. They’re discovered within the coldest areas of the world. These areas are the North and South poles and the excessive mountain valleys. The low temperatures in these locations permit giant quantities of snow to construct up and switch into ice.
