Surface Area of Earth: 510,072,000 square kilometres (total) or 200,000,000 (two hundred million) square miles.
149,000,000 square kilometres (land only).
510,065,600 km2 (see related link) of which 148,939,100 km2 (29.2 %) is land and 361,126,400 km2 (70.8 %) is water.
The Earth's land surface can be divided into different types: 20% covered by snow, 20% mountains, 20% dry land, 30% good land that can be farmed, 10% land that doesn't have topsoil.

Note: The above values are approximations. The Earth is covered in "bumps, lumps, and valleys" which increase the usable surface area. The more accurately they are measured, the larger the surface area of the Earth appears. So if one were to measure so accurately as to be taking the 'bumpiness' of individual molecules into account, then the eventual "surface area" of the Earth would be significantly larger than the above answer.
nothing
Deserts cover 33% of the land surface of the earth.
no water covers 71% of the earths surface and land 29%
A large tall rocky area of land that protrudes from the earth's surface is a mountain. Mountains are formed by the bending and buckling of the rock under the land.
Because Earth is very very large and we live just on the very surface.

Most of the earths surface is covered with water. There is land under that water though, below the surface.

An island
About one third of the land surface of the earth is desert.
A mountain is a natural, large elevation in the Earths surface. A basin is a depression in the Earths surface containing water.
Roughly 71% of Earth is covered by water and because that is well over half there is more water than land on Earths surface
