The Arctic Ocean is the smallest ocean in the world and is about 8 percent of the size of the Pacific Ocean. Its water is consistently cold with temperatures ranging between minus 30 to minus 70 degrees Celsius throughout the year. When the icy water turns into an ice sheet, it forms a mass that is


The Atlantic Ocean covers nearly 77 million square miles, has over 69,000 miles of coastline, and is divided into the north Atlantic Ocean and south Atlantic Ocean. The Atlantic Ocean lies between North America and South America in the west and Europe and Africa in the east. It runs from Greenland s


The Earth's oceans form this planet's most extensive habitat. Oceans span pole to pole and reach around the globe. Seas and oceans stretch from pole to pole and reach around the globe. They cover more than 70 percent of the Earth's surface and hold in excess of 300 million cubic miles of water. The
