Correct Answer: the temperature of the Earth is increasing

Solution : The correct option is the temperature of Earth is increasing.

The greenhouse effect is a natural process in which greenhouse gases in the Earth's atmosphere trap heat from the sun. This stored heat warms the planet's surface and contributes to the planet's temperature remaining suitable for life. However, human activities, such as burning fossil fuels, deforestation, and industrial processes, have led to global warming, causing the Earth's average temperature to rise over time.
