Although we are not completely certain about the origin of water on Earth, it seems that there have been a lot of comet impacts, much earlier in the Earth's history, and those comets brought our planet lots of water, which now covers most of the surface of the Earth.
the oceans
The earth is actually mostly covered by water. 73% of the earth is covered by water and only 3% is freshgrasslands
Where on earth surface does most precipitation fall
Gold and silver
The main source is formed by sea and oceans.
Most of earth's surface water is in the oceans. The second largest bodies are the polar ice caps. Groundwater (water below the surface) exceeds that in all earth's freshwater lakes, rivers, and streams--which account for the remainder of earth's surface water.
Most of the earths surface is covered with water. There is land under that water though, below the surface.
Well! the earth is covered by water which 70% and the part of the earth have oceans so the part that holds the most water is oceans.
the oceans
Water is evaporated from oceans, seas, lakes, rivers.
Warm, shallow seas covered much of Earth's surface during early Paleozoic time.
The earth is actually mostly covered by water. 73% of the earth is covered by water and only 3% is freshgrasslands
In the Sea/Oceans, Lakes, Rivers, Ponds, Puddles, Streams etc.
Liquid water--oceans, seas, lakes, rivers, aquifers, and streams.
oceans, in solution.
The Oceans
Approximately 75% of the Earth's surface is covered by saltwater oceans.About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. But water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog.
