Answer:
Our Environment
Our environment is everything that surrounds us- from the trees, mountains, roads, buildings, things and even people. It is a combination of both natural and human-made elements. These elements are divided into two types: Biotic and Abiotic. Biotic elements are all the living organisms. Abiotic elements include all the non-living things.
Explanation:
Natural Environment
Everything that is not human-made comes under natural environment. Land, air, water, plants and animals all comprise the natural environment. Let us learn about the different domains of the natural environment. These are the lithosphere, hydrosphere, atmosphere and biosphere.
The lithosphere is the solid crust or the hard top layer of the earth. It is made up of rocks and minerals and covered with a thin layer of soil. The lithosphere is an irregular surface with mountains, plateaus, plains, valleys, landforms, etc. It is the domain that provides us with forests, grasslands for grazing, land for agriculture and housing. It is also a source of minerals.
Hydrosphere is the domain of water. It comprises of the various sources of water and different types of water bodies like rivers, lakes, seas, oceans, estuaries, etc. It is essential for all living organisms.
The atmosphere is the thin layer of air that surrounds the earth. It is held by the gravitational force of the earth. The Atmosphere protects us from the harmful UV rays from the sun by blocking them out. It contains a number of gases like oxygen, which is essential for life, dust and water vapour. Changes in atmosphere bring changes in weather and climate.
All life makes up the biosphere. It is the zone of the earth where land, water and air interact with each other to support life.
Ecosystem
What is an ecosystem? All plants, animals and human beings depend on each other. The relation between living organisms, as well as the relation between living organisms and their environment, form an ecosystem. An ocean is an example of an ecosystem because it comprises of living organisms, land, air ( in dissolved form) and water of course.
