Answer:
Nature, place, people, things, etc. that surround the living organisms make the environment. The environment can broadly be classified into the natural and human environment. It is a combination of both natural as well as man-made phenomena.
The natural environment comprises biotic (plants and animals) and abiotic-conditions(land, water, air, etc.), whereas the man-made phenomena comprise the activities and interactions among human beings (roads, bridges, etc.).
Natural Environment
Land, water, air, plants and animals comprise the natural environment.
Lithosphere, atmosphere, hydrosphere and biosphere are the four domains of the natural environment.
The lithosphere is the solid crust or the outermost layer of the earth where we live. It contains landforms like mountains, plateaus, plains and valleys.
The hydrosphere is the domain of water. It comprises water bodies like rivers, lakes, seas, oceans, etc.
The atmosphere is the thin layer of air that surrounds the earth. It protects us from the harmful rays and scorching heat of the sun.
The biosphere is a narrow zone of the earth where land, water and air interact with each other to support life.
