Geosphere

Definition - What does Geosphere mean?

Geosphere is a portion of the earth's system that represents the interiors of the earth. This includes the shape of the surface of earth, landforms, rocks, rock physical, chemical properties and the minerals it holds. Many people refer to geosphere as a collective name for lithosphere, cryosphere and the atmosphere. The earth's crust is comprised of many types of rocks and large varieties of minerals.

Petropedia explains Geosphere

When we consider the earth as a body of massive mass, on paper it appears to be spherical or circular in shape; however, the fact is that the geosphere of the earth is in such a way that it does not look spherical in shape when seen from the galaxy. It is in an oblate spheroidal shape with a radius of 6357 km from the center of the North Pole and 6378 km from the center of the equator.

Around 98% of the earth's crust mainly consists of just 8 elements:

  • Oxygen – 47%
  • Silica – 27%
  • Aluminum – 8%
  • Iron – 5%
  • Calcium – 4%
  • Sodium – 2.83%
  • Potassium – 2.7%
  • Magnesium – 2.09%
