Natural Environment

Every day in our surroundings we see plants and animals around us.

The surrounding in which a person, animal or plant lives is called an environment.

Apart from the living things in the environment, there are non-living things like land, water, and air.

Land, water, air and plants are a part of the natural environment. These are important for the survival of living beings.

Land, water, and air are present in the lithosphere, the hydrosphere, and the atmosphere respectively.

Let us discuss these spheres in the natural environment one by one

Lithosphere

The lithosphere is the hard top layer of the Earth, made up of rocks, minerals and covered with soil.

It is an irregular surface with various landforms such as mountains, plains, plateaus, and valleys.

These landforms are found over the continents and also on the ocean floors.

The lithosphere also provides us with forests, grasslands, land for agriculture and building houses.

Hydrosphere

All the water over the Earth's surface is known as Hydrosphere.

It consists of various sources of water and different types of water bodies like rivers, lakes, seas, and others.

Water is needed for the survival of all living organisms.

Atmosphere

The atmosphere is a thin layer of air that surrounds the Earth like a blanket.

The gravitational pull of the Earth holds the atmosphere around it.

The atmosphere protects us from the harmful rays of the Sun and the heat from it.

It consists of a number of gases, dust and water vapour.

Changes in the atmosphere result in climatic and weather change.

Biosphere

The biosphere is a narrow zone of the Earth where land, water and air interact with each other to support life.

The biosphere has both the plant and animal kingdom.

So the biosphere is also called the living world.

Revision

The surrounding in which a living being lives and operates is known as environment.

Natural environments consist of the Lithosphere, Hydrosphere, Atmosphere and Biosphere.

The hardtop layer of the Earth made up of rocks, minerals and soil is called lithosphere. It has forests, grasslands and others.

All the water over the earth's surface is known as hydrosphere. Water is very essential for the survival of living beings.

The blanket of air surrounding the earth is known as the atmosphere. It protects us from the harmful sun rays and its heat.

The biosphere has land, water, and air. It includes plants and animals and also known as the living world.
