* How much of the Earth is covered in water? Approximately 71% of the Earth's surface is covered in water. That's a lot!

* What kind of water? This water comes in various forms:

* Oceans: The vast majority of Earth's water is found in the oceans, which cover about 96.5% of the planet's total water.

* Freshwater: Only about 2.5% of the Earth's water is freshwater, and most of that is locked up in glaciers and ice caps. The rest is found in lakes, rivers, and groundwater.

So, to sum it up:

* The majority of the Earth's surface is covered in water, primarily in the form of oceans.

* Freshwater makes up a much smaller percentage, but it's essential for life.
