What is The Lithosphere and Why is it Important?

The Lithosphere is the outer layer of the Earth its depth extends to 120 miles deep, it includes the upper portions of the mantle and the crust, thus it is bordered by both the atmosphere and the asthenosphere. The Lithosphere is also one of the Earth’s coolest (temperature) layers, there are two layers of the lithosphere, the Oceanic Lithosphere and the Continental Lithosphere, the former is, as the name suggests deals with Oceanic crust and is slightly denser than the latter. These both cause plate tectonics, which is the interaction of the huge slabs of the lithosphere (There are 15 major plates, usually activity happens when they collide, diverge, and slide together, these are made possible by Convection Currents, which is heat flowing from the mantle) these slabs of the lithosphere cause natural disasters like Earthquakes, Volcanos, and even deep Oceanic trenches from these tectonic plates.




  • Oceanic lithosphere, which is the oceanic crust and is in the ocean basins (average density is of about 2.9 grams per cubic centimeter)
  • Continental lithosphere, which is the continental crust (average density of about 2.7 grams per cubic centimeter)

What Animals Live in The Lithosphere

The Lithosphere is one of the most important layers of Earth because it is what all living organisms (as well as dead ones) live and thrive on top of. Every living life form, including humans, live on top of the Lithosphere, so without this layer of crust to separate us from the Asthenosphere, there wouldn’t be life. Those are the organisms that live on top of Lithosphere. Organisms that actually live in the Lithosphere includes: worms, moles, burrowing insects, rats, mice, foxes, wolves, plant roots, prairie dogs, groundhogs, meerkats, pupfish, and more. The Lithosphere is essential to life on Earth.

How Does The Lithosphere Interact with other Spheres

The lithosphere is only one of 5 spheres. All of these spheres interact to influence elements such as biodiversity, ocean salinity, and landscape. The pedosphere is the part of the lithosphere that is made of soil and dirt. The pedosphere was created by the interaction of the lithosphere, cryosphere, atmosphere, hydrosphere, and biosphere. The components of the biosphere, such as plant and animal remains, combine with the eroded rocks to create nutritious soil, also called the pedosphere.The lithosphere also interacts with the cryosphere, hydrosphere, and atmosphere to influence temperature changes on Earth.
