Before a volcanic eruption, the Earth's average surface temperature was constant. The eruption put particles high into the atmosphere. Measurements showed that these particles increased the rate at which radiation from the Sun was reflected back into space. Immediately after the eruption, the rate at which the Earth emitted radiation was unchanged.
Give the change in the rate at which radiation from the Sun is absorbed by the Earth.
Using your answer to part (a), explain how the Earth's average surface temperature changes immediately after the eruption.
