Question 1:

What is the greenhouse effect?

Explanation: The greenhouse effect refers to the process by which certain gases in the Earth's atmosphere trap heat and warm the planet's surface. These gases, known as greenhouse gases, include carbon dioxide, methane, and water vapor.

Question 2:

Which of the following is a greenhouse gas?

Explanation: Carbon dioxide (CO2) is a greenhouse gas that contributes to the greenhouse effect. While nitrogen and oxygen are the main components of the Earth's atmosphere, they do not have significant greenhouse warming effects.

Question 3:

What is the primary cause of the increase in greenhouse gases in the atmosphere?

Explanation: The primary cause of the increase in greenhouse gases in the atmosphere is human activities, particularly the burning of fossil fuels such as coal, oil, and natural gas. These activities release carbon dioxide and other greenhouse gases into the atmosphere.

Question 4:

What is the main consequence of the greenhouse effect?

Explanation: The greenhouse effect leads to various consequences, including rising sea levels, increased precipitation in some regions, and more frequent and intense heatwaves. These changes in climate patterns have significant impacts on ecosystems, communities, and economies.

Question 5:

What is the relationship between greenhouse gases and global warming?

Explanation: Greenhouse gases contribute to global warming by trapping heat in the Earth's atmosphere. When these gases accumulate due to human activities, they enhance the natural greenhouse effect and lead to an increase in global temperatures.
