Which of the following would lead to an increase in the temperature of Earth?

Question

Quizplus · Accepted Answer

Glaciers help to reflect sunlight back into space, so melting glaciers means less sunlight is being reflected and more is being absorbed into Earth's surface, leading to an increase in temperature.

Answer: A
 Volcanic ash in the atmosphere can block sunlight from reaching Earth's surface, leading to a decrease in temperature. However, if there is an increase in volcanic ash, it can trap heat in the atmosphere, leading to an increase in temperature.

The other choices, B and D, do not necessarily have a direct impact on the temperature of Earth. The growth of forested land may have an indirect impact by absorbing carbon dioxide from the atmosphere, but it is not a significant enough factor to have a direct impact on temperature. A change in Earth's tilt can affect the distribution of sunlight on Earth, but it does not necessarily lead to a significant increase or decrease in temperature.
