Hey!!
Lithosphere, Atmosphere, Hydrosphere and Biosphere are part of the physical environment.
→ Lithosphere
The lithosphere is the outermost, solid surface layer of the Earth. It is also sometimes called the crust. The word lithosphere is derived from the Greek word lithos, which means 'stones'. The surface of the Earth is not flat. It is uneven with different kinds of landforms like mountains, hills, valleys and plateaus. The crust is covered by a thin layer of soil which is of vital importance for life.
------------------------------------------------------------------------------
→ Atmosphere
The layer of air that surrounds the Earth is called the atmosphere. The atmosphere is a mixture of gases, dust and water vapour. The word atmosphere is derived from the Greek word atmos, which means 'vapour'. The gravitational force of the Earth holds the atmosphere around it.
-----------------------------------------------------------------------
→ Hydrosphere
Hydrosphere is derived from the Greek word hydor, meaning water. It refers to the water on the Earth. The Earth is called the Blue Planet because 71% of its surface is covered with water and only 29% with land. Water is found as solid ice in glaciers and ice sheet. It is found as liquid water in oceans, rivers etc.
--------------------------------------------------------------------------------
→ Biosphere
The Biosphere is the narrow zone of contact between land, water and air, where life forms exist. It is called the living world or the biological environment. Everything in the biosphere is interconnected and independent.
