The gaseous covering above the Earth is referred to as the atmosphere. Atmosphere A cormorant bird taking flight over water. All other parts support life, from the microorganisms, and tall trees, to the largest animals, by giving them proper shelter and nourishment.

The Earth's lower mantle and core are the only parts that do not support life and are not, therefore, a part of the biosphere.

The lithosphere comprises solid landmasses like the continents and islands. The lithosphere is referred to as the biosphere's terrestrial component. Lithosphere Dendrobaena is a burrowing annelid worm that lives in the soil. Only those portions are regarded as a component of the biosphere where life is found and sustained. However, not all of them are home to or are inhabited by living organisms. The biosphere comprises three components: lithosphere, atmosphere, and hydrosphere. Eduard Suess created the term 'biosphere' because he believed it was crucial to try to understand life entirely as opposed to focusing on specific organisms. At the time, no one understood plate tectonics. The Greek words 'bios' for life and 'sphaira' for the shape of the Earth are the origins of the word 'biosphere.' More than a century ago, the Austrian geologist Eduard Suess used the term 'biosphere' for the first time in his four-volume work Das Antlitz der Erde, or 'The Face of the Earth.' The only explanation Suess could offer at that time for the existence of marine fossils in the mountains was that the waters of the Tethys Ocean had flooded the entire Earth, not that the continents had actually moved apart and transformed. Why Is It Called Biosphere? The Four Spheres Of The Earth. Thus, the biosphere can alternatively be defined as the total of all the ecosystems on Earth. In this way, the biosphere blends with the three other spheres of the Earth, namely the atmosphere, the lithosphere, and the hydrosphere. Therefore, whether life is found on the Earth's surface, high up in the air, or below the ground, everything forms a part of the greater biosphere. The biosphere encompasses everything from the deepest tree roots to the shadowy depths of the ocean, lush rain forests, and lofty mountaintops. The word 'biosphere' was initially used in 1875 by the Austrian geologist Eduard Suess to refer to the region of the Earth where life can be found.

Also referred to as the 'Ecosphere,' the biosphere is a relatively thin zone of the Earth's surface that supports life.
