Would you please tell me why ice floats and what are its elments.
Ice has many different forms.
Sea ice forms on the surface of the sea in cold regions. Once it forms it can last just a few hours or it can last for several years before it finally moves into warmer waters and melts. If it lasts several years it can be several meters thick. Snow that falls on the land in cold regions and in mountains can accumulate over many years to form glacial ice. Some glaciers are very large.
