The correct answer is (b) Carbon dioxide.
Carbon dioxide is a greenhouse gas that traps heat in the atmosphere. This trapping of heat causes the Earth’s temperature to rise. The rise in Earth’s temperature is causing climate change.
Carbon monoxide is a poisonous gas that is not a greenhouse gas. Oxygen is a gas that is essential for life and is not a greenhouse gas.
The greenhouse effect is a natural process that helps to keep the Earth’s temperature warm. However, human activities are increasing the amount of greenhouse gases in the atmosphere, which is causing the Earth’s temperature to rise at an alarming rate. This rise in temperature is causing climate change, which is having a devastating impact on the planet.
We need to take action to reduce our emissions of greenhouse gases and to protect our planet from the effects of climate change. We can do this by making changes to the way we live, work, and travel. We can also support policies that promote renewable energy and energy efficiency.
Together, we can make a difference.
