How old is the sea?
Joly, with Murray’s figures for rainfall, run-off, and the average composition of river water, combined with Dittmar’s analyses of oceanic salts and an estimate of the mass of the ocean, deduced an uncorrected value for the age of the ocean of 97,600,000 years.
What is the world’s oldest ocean?
The Pacific
The Pacific is the oldest of the existing ocean basins. Its oldest rocks have been dated at about 200 million years.
When did water first appear on Earth?

Is water older than the sun?
Around 70 percent of the Earth’s surface is comprised of water, and our big, blue, planet is filled with rivers, streams, and oceans that defy everything scientists have come to learn about the formation of Earth.
What is the oldest ocean?
The world’s oceans are constantly changing in size as tectonics makes the great plates of the Earth’s crust slowly move around. The Pacific is the oldest of the current ocean basins, with the oldest rocks on its floor being around 200 million years old.
When was the first ocean formed?
It officially became an ocean in 2000, and was formed from the southern sections of the Atlantic, Indian, and Pacific oceans . The oceans influenced the formation of the land surface of the Earth as it is known today. During several periods of the Earth’s history large parts of North America were covered by the ocean.
What is the largest sea in the world?
The Bay of Bengal, the largest seas in the world, forms the northeastern part of the Indian Ocean. It resembles a triangle in shape, and is bordered mostly by the Eastern Coast of India, southern coast of Bangladesh and Sri Lanka to the west and Burma (Myanmar) and the Andaman and Nicobar Islands (part of India) to the east.
What are facts about the ocean?
44 Facts About the Ocean (in no particular order) Earth is mostly water. Ninety four percent of all life forms on Earth are aquatic. Humans have documented space and other planets better than they have mapped the ocean floor. Oceans have an average depth of two and a half miles (13200 ft). The ocean is three percent salt.
