The earth surface is mostly water. We are taught that 75% (3/4) of the earths surface is water.
A negligible percentage, significantly less than 1%. Rivers occur only of the surface of the earth, around 70% of which is oceans. Rivers occupy a tine proportion of the remaining surface. Compared to the radius of the earth their depth is negligible so that they occupy a minuscule proportion of the earth's volume.
Primarily the erosive power of wind and water. Rivers and rain will wear away even the hardest stone.
Surprisingly little. Water covers a little under three-quarters of Earth's surface, but it's almost all on (or just below) the surface, so a relatively tiny fraction of Earth is water.
Approximately 70.8% of Earth's surface is covered by water (oceans, seas, lakes, and rivers), while the remaining 29.2% is land (continents and islands).
Almost 3/4 of the Earth's surface is covered by water (71%).Predominantly the oceans, but lakes, seas, and rivers also cover some of the Earth's surface with water.

The Earth is made of approximately 71% water. Of this amount, 97.5 percent is contained in the saltwater oceans while the remaining 2.5 percent is in freshwater lakes and rivers and in the polar ice.
About %70 of Earth is covered by water Of that 70 percent about %96.5 is saltwater
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.
Approximately 71% of the Earth's surface is covered by the hydrosphere, which includes all forms of water such as oceans, lakes, rivers, and glaciers. This makes water the most abundant substance on Earth.
75% of the Earth's surface makes up the hydrosphere.
Water is evaporated from oceans, seas, lakes, rivers.

Water which moves over the earths surface after having precipitated (rain, snow, etc) is known as runoff. Most rivers get the majority of their water from precipitation runoff.
