In winter water freezes and becomes ice and snow in cold weather.
In spring and summer ice and snow melt and turn into liquid water again.
The coldest areas on Earth are the North Pole and the South Pole.
These areas are covered with giant blocks of ice.
Sometimes, large pieces of ice break off and float in the ocean.
These are called icebergs.
