The amount of solar heating can increase from:

A) a decrease in sunspot activity and energy output from the Sun
B) a decrease in snow and ice cover on Earth's surface
C) a decrease in the amount of greenhouse gases
D) a huge volcanic eruption that adds ash and dust to the atmosphere

Solar Heating

The process of increasing the temperature of an object, substance, or space using energy directly from the sun.

Sunspot Activity

Phenomena on the Sun's surface that appear as dark spots due to lower temperatures, often associated with magnetic activity.

Greenhouse Gases

Gases in Earth's atmosphere, such as carbon dioxide and methane, that trap heat and contribute to global warming.
