Question

what is one way volcanic eruptions can affect climate?
a. ash blocks sunlight, causing temperatures to drop.
b. temperatures rise because of the heat from the lava.
c. ash repels water droplets, reducing rainfall.
d. scorched land creates drought conditions.

Explanation:

Volcanic eruptions release ash into the atmosphere. This ash can block sunlight from reaching the Earth's surface, leading to a cooling effect and a drop in temperatures. Lava heat has a local - not a significant climate - wide impact. Ash does not repel water droplets in a way that affects rainfall on a climate - wide scale, and scorched land is more of a local consequence rather than a primary climate - affecting factor.

Answer:

A. Ash blocks sunlight, causing temperatures to drop.
