Environment

The environment is the surrounding we live in. It consists of both the biotic and the abiotic components. Our environment includes mountains, rivers, lakes, animals, plants, people, etc.

  • Biotic Components: All the living organisms in our environment are said to be biotic components. Example: Plants and animals.

  • Abiotic Components: All the non-living organisms in the environment form the abiotic components. Example: Land and mountain.


Types of Environment

Our environment can be classified into two types:

Natural Environment: The natural environment consists of all the things occurring naturally like land, water, plants, air etc. The natural environment is further divided into different domains:

  • Lithosphere: The solid crust or the hard top layer of the earth that is made up of rocks and minerals and with a thin layer of soil. Eg: mountains, plateaus, highlands, etc.

  • Hydrosphere: Hydrosphere basically consists of all the water bodies on the surface of the planet earth. This includes the sea, rivers, lakes, etc.

  • Atmosphere: This thin layer or blanket of air that surrounds the earth is known as the Atmosphere. This layer protects us from the harmful ultraviolet rays of the sun. This consists of a number of gases, dust and water vapour.

  • Biosphere: The biosphere of the earth includes living organisms present in our environment. All the plants and animals are a part of our biosphere.


Human Environment: This is a type of environment where human beings modify their surroundings as per their own requirements. The early human beings lived a very simple life and fulfilled their needs from the natural resources available around them. With time and development, human needs started increasing, with these growing needs humans began to change and modify their environment around. For example, the wheel was invented, people started a barter system, and trade and commerce started.


Then came the time of various revolutions that changed the outlook of the environment as a whole. With the industrial revolution, people began setting up industries by cutting down forests. Urbanisation began, and people started clearing forests and started construction of human settlements. Transportation began to develop. There were various other developments too that changed the way of living of the humans and they started creating their own environment. We humans must learn the optimum utilisation of resources.


Ecosystem: An ecosystem is an interaction between all the living beings with their physical and chemical environment i.e their surroundings. Generally, they are dependent upon each other. It is a community or gathering of living life forms that live in and associate with one another in a particular environment. For example, tropical forests are environments composed of living creatures, such as trees, plants, bugs, and miniature living beings, which are inconsistent with other physical or substance segments.


Components of Environment:

Discover the different components of the environment, including natural components like air, water, land, and living organisms. Understand how human activities impact these components and the need for their conservation.

There are several nutrient cycles that tend to link so many components of the physical and the living nature. Some of the examples of an ecosystem would include grassland, a rainforest, a mountain, a desert, and so much more.

2. What are the Biotic Components in Class 7 Geography Chapter 1 Notes?

According to The Environment Class 7 Notes, Biotic components comprise the living things that make up the environment such as plants and animal life.

3. What are Abiotic Components in Class 7 Geography Chapter 1?

Abiotic components can be defined as those components of the environment which are of non-living, physical, and chemical nature. Some examples include air, water, wind, light, minerals, and glass.

4. What is the difference between the Natural and Human Environment?

The natural environment consists of all the natural forces such as air, water, land, animals, plants, and much more. The human environment consists of human interactions with the environment.

5. What do you understand about the lithosphere in Our Environment Class 7 Notes PDF?

The lithosphere is the subdivision of the natural environment. It can be defined as the solid surface or the hard layer of the earth's surface. It is built of minerals, stones, pebbles, and rocks. This top crust of the earth is covered with a thin film of soil. The surface of the lithosphere is irregular and includes natural landforms like plateaus, mountains, valleys, deserts, plains, etc. It plays a vital role in our lives as it gives us forests for getting food commodities, land for cultivation and human settlement, and grasslands for grazing. Also, it is a natural reservoir of minerals.

6. What is the atmosphere in Geography Class 7? 

The atmosphere is a thin film of air that surrounds the earth. It is made of different types of gases like nitrogen, oxygen, carbon dioxide, sulphur, water vapours, dust particles, etc. The atmosphere sticks to the earth through the gravitational force. This force is responsible for holding the atmosphere across the earth. It prevents humankind from scorching and avoids the harmful rays of the Sun. The changes in the atmosphere initiate modifications in the weather and climate.

7. How are humans responsible for modifying the natural environment?

Human activities are responsible for changing the natural environment. The needs of people are increasing day by day. Hence, they tend to change the environment to fulfil their requirements. Human beings sometimes destroy nature to get precious resources like wood, minerals, food, and other materials to earn a huge amount of money. Many constructors destroy natural vegetation to build industries, roads, corporate offices, etc. This way humans are changing ecosystems to date.

8. Write different domains of the environment. 

The different domains of the environment are:

  • Lithosphere - It is the uppermost surface of the earth. Hence, it’s known as the “Earth’s Crust”. It is built of minerals and rock. It is surrounded by a thin film of soil. It gives us grasslands, forests, etc. 

  • Atmosphere - It’s a slim layer of air that surrounds our planet earth. The atmosphere is made up of dust particles, water vapours, gases like hydrogen, oxygen, etc. 

  • Hydrosphere - Hydrosphere refers to the water reservoirs present on the earth. It consists of water reservoirs like rivers, lakes, seas. 

  • Biosphere - It comprises living creatures like plants and animals.

9. How have human beings adapted to the environment?

Human beings have been dependent on nature since ancient times. They have been interacting with nature and moulding themselves according to it. Ancient humans have changed themselves so that they can live in their natural surroundings. They had an easy life and fulfilled their needs from the environment itself. With gradual development, humans learnt to grow crops and rear animals for their livelihood. Steadily, different modes of transportation arose and trade started. In the modern world, the invention of the Internet has made everything easy. This is how humans have adapted to nature.

10. Define the environment.

The surrounding we live in is composed of various living and nonliving components that make our existence possible and are known as the environment. The living components include plants and animals whereas the non-living components include the land, air, water, etc.

11. Define the terms Biotic and Abiotic in Chapter 1 Environment Geography Class 7.

The term "biotic" is cast by the combination of two terms, "bio", which means life, and "ic", which means like. In this manner, the term implies life-like and is identified with all the living substances present in an ecosystem.


Plants, Animals, fisheries, and so forth comprise the biotic elements. The term abiotic alludes to all the nonliving elements present in an environment. Daylight, water, and land all comprise abiotic factors.

12. Explain the Natural Environment?

The natural environment incorporates all living and nonliving things occurring naturally or free gifts of nature. The natural environment incorporates land, water, air, plants, and animals. This environment incorporates the connection of every living species, atmosphere, climate, and common assets that influence human existence.

13. How can I effectively revise Geography and Social Science?

To revise Social Science effectively, create a study schedule, review your class notes and textbooks, make concise summary notes, use visual aids like charts or diagrams, practice answering past exam questions, and seek clarification from your teachers or our Vedantu master teachers if needed.
