How do volcanic eruptions effect the composition of the atmosphere?

a. volcanic eruptions add greenhouse gases to the atmosphere, but they take dust particles out of it.

b. volcanic eruptions take greenhouse gases and dust particles out of the atmosphere.

c. volcanic eruptions add fine dust particles to the atmosphere, but they take greenhouse gases out of it.

d. volcanic eruptions add greenhouse gases and fine dust particles to the atmosphere.

D

Explanation:

Volcanic eruptions spew large amounts of dust particles from their surroundings into the atmosphere. Accompanying eruptions are also materials like volcanic ash and gases. These gases contribute immensely to the reserve of greenhouse gases in the atmosphere.

Gases in volcanoes are responsible to a large extent for their explosivity when an eruption occurs. The more the gases, the more explosive a volcano can be. These gases are rich in carbon dioxide, methane, etc. A vast number of them are greenhouse gases.

Dust particles also accompany an eruption. These dust can be suspended for an extended period in the atmosphere by the wind.
