Which is not correct approach to reduce global warming?

zoology global environmental change causes of greenhouse effect global warming adaptation in animals

  1. Cutting down use of fossil fuel

  2. Reducing deforestation

  3. Improving efficiency of energy use

  4. Cutting trees and increasing growth of human population

  5. Reducing emission of greenhouse gases into atmosphere

Show answer
Correct Option: D
Explanation:
To avoid Global Warming: 
1) By utilizing eco-friendly vehicles. 
2) Replace normal glowing light with conservative bright light (CFL) knobs. 
3)Plant more trees. By planting more trees helps in decreasing a dangerous atmospheric deviation as plants use carbon dioxide amid the procedure of photosynthesis, which is the primary driver of Global warming. 

So, the correct option is 'Cutting trees and increasing the growth of the human population'. 

If there was no $CO 2$ in the earth's atmosphere, the temperature of the earth's surface would be ________

zoology global environmental change causes of greenhouse effect global warming adaptation in animals

  1. Same as the present level

  2. More than the present level

  3. Less than the present level

  4. Dependent on $O _2$ content of atmosphere

Show answer
Correct Option: C
Explanation:

Carbon dioxide atmosphere absorbs and stores the energy near the earth's surface when incoming solar radiation is reflected back to the space. If there was no carbon dioxide then there would no absorption of solar energy and hence the temperature of earth's surface would be less than the present level. So, the correct answer is 'Less than the present level'.

The main reason for global warming is?

zoology global environmental change causes of greenhouse effect global warming adaptation in animals

  1. Gradually increasing temperature of the Sun

  2. Gradually increasing temperature in the earth core

  3. Increased accumulation of $CO _2$ in air

  4. Establishment of more industries using exothermic processes

Show answer
Correct Option: A

The release of $CO _2$ into air can cause:

zoology global environmental change causes of greenhouse effect global warming adaptation in animals

  1. Global warming

  2. Eutrophication

  3. Acid rain

  4. Respiratory problems

Show answer
Correct Option: A
Explanation:

Global warming occurs when carbon dioxide and other air pollutants called the greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface.

Hence, the correct answer is 'Global warming'.

Multiple Choice Questions
Global warming can be controlled by

zoology global environmental change causes of greenhouse effect global warming adaptation in animals

  1. Increasing deforestation, reducing efficiency of energy use

  2. Reducing deforestation, cutting down use of fossil fuel

  3. Reducing deforestation, increasing use of fossil fuel

  4. Increasing deforestation, slowing down the growth of human population.

Show answer
Correct Option: B
Explanation:

Global warming refers to the increase in the average temperature of earth due to an excessive amount of greenhouse gases namely CO$ _2$, CH$ _4$ etc. It can be controlled by reducing deforestation. A high plant cover utilizes the major amount of CO$ _2$ from the air. Also another method of control is cutting down the use of fossil fuels which otherwise emits greenhouse gases like CO$ _2$, N$ _2$O etc.

So, the correct answer is option B, reducing deforestation, cutting down use of fossil fuel.

In 2015 and 2017, there was very heavy rain in our state. In 2016, there was no adequate rain. These extreme conditions are due to

zoology global environmental change causes of greenhouse effect global warming adaptation in animals

  1. Uneven distribution of human population

  2. Global warming

  3. Depletion of ground water

  4. Ozone depletion

Show answer
Correct Option: B
Explanation:

Global warming refers to an increase in the overall temperature of the atmosphere due to accumulation of greenhouse gases that trap long wave radiations. Due to this, the water cycle is affected because the cloud formation is erroneous. This causes disturbed pattern of rainfall. Other effects of global warming are shown in the following diagram:
