Approximately 71% of the Earth’s surface is covered by nothing but water i.e. ocean. It is divided into several principal oceans and smaller seas. There are five major oceanic divisions as follows:
- Pacific Ocean
- Atlantic Ocean
- Indian Ocean
- Southern Ocean
- Arctic Ocean
The Pacific Ocean
The Pacific Ocean is the largest of the Earth’s oceanic divisions. According to wikipedia:
It extends from the Arctic in the north to Antarctica in the south, bounded by Asia and Australia in the west and the Americas in the east. At 169.2 million square kilometres (65.3 million square miles) in area, this largest division of the World Ocean – and, in turn, the hydrosphere – covers about 46% of the Earth’s water surface and about 32% of its total surface area, making it larger than all of the Earth’s land area combined. The equator subdivides it into the North Pacific Ocean and South Pacific Ocean. The Mariana Trench in the western North Pacific is the deepest point in the Pacific and in the world, reaching a depth of 10,911 metres (35,798 ft)
The Pacific Ocean is the body of water between Asia and Australia in the west, the Americas in the east, Southern Ocean to the south, and the Arctic Ocean to the north. It joins the Atlantic Ocean at a line drawn due south from Cape Horn, Chile/Argentina to Antarctica, and joins the Indian Ocean at a line drawn due south from Tasmania, Australia to Antarctica.
