Approximately 25% of the earth is dry land.
Three quarters of dry land on Earth is covered by sedimentary rock.
The Earth's surface was covered mostly with water. There was a very small part of land that was dry and above water.
All of Mars is "dry land" (even under the ice caps of frozen water and frozen carbon dioxide), while most of the Earth's surface (71%) is covered by water. So even though Mars has only 28% of Earth's surface area, the amount of dry land is about the same (144.8 million km2 compared to Earth's 144.9 million km2).
2/3 of the planet is covered by water. Then we have land. Land, sometimes referred to as dry land, is the solid surface of the Earth that is not permanently covered by water.
Technically, most of the Earth is rock. As a surface feature, their is more water covering dry land than their is dry land.
Depends on what you mean?Do you mean only on dry land? Or are you asking to include sea life as well?I can tell you about the percentage for the entireEarth's mass, however; meaning it calculates the entire population of the Earth including the sea.The entire Earth's population of living organisms' number fluctuates daily as some organisms only live for a day; but on average, about 76% of the Earth's mass is live organisms. (This is including aquatic life.)
Great Plains, it is covered in DRY grasslands and has land that increases towards the Rockies.

About 20%
All of the surface of Mars can be classified as dry land, even the frozen polar caps, because there is no liquid water on the surface of Mars. The total area of land on Mars is nearly the same as the "land" area of Earth, about 144,798,750 km2.
Mars only has about 28% the surface area of the Earth. What's interesting is that number matches the land area of Earth, so the total surface of Mars is roughly the same as the dry land surface of Earth.
