Why there is more water on Earth than land?

Answer 1: It has to do with the different kinds of rocks in the Earth’s crust: continents are made of granite, and ocean crust is made of basalt. The more granite there is, the more continent there is, and the more of the Earth’s surface rises above the ocean basins. Water fills the basins.

What is the difference between space and the oceans?

How much of the Earth’s Ocean is undiscovered?

More than eighty percent of our ocean is unmapped, unobserved, and unexplored. The ocean is the lifeblood of Earth, covering more than 70 percent of the planet’s surface, driving weather, regulating temperature, and ultimately supporting all living organisms. Throughout history, the ocean has been a vital source of sustenance, transport,…
