Basic concepts about the environment
1. What is the environment?
Answer: The term environment means the surrounding conditions. This Earth contains various organic and inorganic matter. The environment includes heat, wind, and energy. Thus, the environment consists of all organic and inorganic components. That is, air, water, soil, wind. The environment is energy as well as the relationships with different kinds of animals and people.
2. What are the different components of the environment?
Answer: The various components of the environment are:
1. 1. Inorganic components
2. 2. Organic ingredients
3. 3. The power component
The inorganic or physical environment can be divided into three categories:
1. 1. Terrestrial (solid)
2. 2. hydrosphere (liquid)
3. 3. atmosphere (gas)
Organic components consist of plants and animals including humans.
Energy components are solar energy, geothermal energy, hydro-electric energy, nuclear energy, etc.
3. What are the different parts of the environment?
Answer: The different parts of the environment are:
1. 1. Atmosphere (Atmosphere)
2. 2. Hydrosphere
3. 3. Lithosphere
4. The The biosphere
4. The State the main components of the atmosphere.
Answer: The main components of the atmosphere are:
Major Constituents: Nitrogen, N2 (78.09%)
Oxygen, O 2 (20.94%)
Light components: Argon, Ar (9.34 × 10-1 %)
Carbon dioxide (CO 2, 3.25 × 10-2%)
Very small amounts of gases: neon, helium, methane, water vapor, krypton, nitrous oxide, xenon, hydrogen, sulfur dioxide, ozone, ammonia, carbon monoxide, nitrogen dioxide, etc.
5. What is the role of the ozone gas layer in the stratosphere?
Answer: Ozone gas is diffused in the stratosphere region of the atmosphere. This ozone gas plays an important role for us. Ozone gas acts as a shield for life on Earth from the harmful effects of the Sun's ultraviolet rays.
6. What do you understand about environmental education?
Answer:
7. What are the broad tenets of environmental education?
Answer: The broad guidelines of environmental education are:
1. Sensitivity and awareness to the environment and environmental challenges.
2. To gain understanding and knowledge about the environment and environmental challenges.
3. An attitude of concern for the environment and a mindset to maintain and improve environmental quality.
4. The Skills in assisting in addressing environmental challenges and marking them.
5. Participation in initiatives aimed at solving in environmental challenges.
8. State the basic principles of environmental education.
Answer: The basic principles of environmental education are:
- Emphasis on the interrelationship of various subjects in education.
- Consider the environment as a whole.
- Continuous education, beginning at the preschool level and continuing across all formal and informal levels.
- native. Critically examine major environmental issues from regional, national and international perspectives.
- Conduct studies on current and future environmental trends and conditions.
- Help students discover the real causes and symptoms of environmental problems and plan accordingly.
- Finally, emphasis should be placed on raising the need and values of local, national and international cooperation to address environmental issues.
Answer: Environmental education is a versatile subject. To learn about the environment and its complex phenomena, one needs to acquire knowledge in various subjects. Botany, zoology, biotechnology, bioengineering, microbiology, genetics, biochemistry, etc. help in understanding biological components and their interactions. Physics, chemistry, mathematics, statistics, etc. help to understand various phenomena in the environment. Computer science, information technology, etc. are essential parts of environmental education. Similarly, environmental engineering is essential for pollution control. Other branches of engineering, such as chemistry, civil, technical and new innovative technologies are also involved in environmental protection. Green chemistry plays a specific and very clear role in protecting the destroyed environment. Social theory, economics, education, philosophy, etc. are also related in various ways. Environmental laws are always enforced to protect the environment. Therefore, environmental education carries the character of a multidisciplinary approach in which various aspects are dealt with from a multi-faceted perspective.
10. How does environmental awareness help in keeping our environment safe?
Answer:The world today is facing major problems like environmental degradation and pollution. Various forms of pollution, rapid depletion of forest resources, rapid population explosion, expansion of industrialization, unplanned urbanization, mining, land degradation etc. have created ecosystem imbalances in recent years. Human quest for economic development is primarily responsible for the ruthless use of natural resources. Moreover, mankind has indiscriminately exploited or ruthlessly destroyed natural resources with its extremely materialistic, greedy and luxurious lifestyle. All these activities are threatening the survival of many living species. Therefore, it is necessary to create mass awareness to protect the environment by preventing further degradation. Environmental problems can be solved in the best way if the people are ecologically aware. No government can solve this problem by simply implementing certain environmental protection laws without the cooperation of the people. The public must be environmentally educated. They need to know that if we destroy our environment today, we will suffer the consequences tomorrow and our future generations will face great danger. We are a part of the environment and it is our duty to protect the environment.
