Question

Which substance may lower air temperatures after a volcanic eruption?

Answer 1

Answer:

Sulfur Dioxide

Explanation:

During an eruption, volcanoes let off greenhouse gases such as sulfur dioxide which shade sunlight and cause temporary cooling. Lava is molten rock that reaches the earth's surface and does not cool until it solidifies. Water vapor cannot be produced through processes during volcanic eruptions. Carbon dioxide may be a greenhouse gas, but cannot be produced during an volcanic eruption.
