Question

Quizplus · Accepted Answer

All of the options listed can be the effect of fine volcanic dust in the high atmosphere. It can reduce the amount of sunlight that reaches Earth's surface, leading to a suppression of photosynthesis. The dust can also reflect sunlight back into space, causing a cooling effect on the Earth's surface temperature. Large amounts of volcanic dust can damage aircraft, and the dust particles can affect the atmosphere's composition, leading to unusual weather patterns.
