Which substance may lower air temperatures after a volcanic eruption? a. lava b. sulfur dioxide c. carbon dioxide d. water vapor

Sulfure dioxide , i think

B. sulfur dioxide

When volcanoes erupt they release mixture of gases, and particles in the surrounding air. Gas sulphur dioxide and ash exhibit a cooling effect on the surrounding environment after the volcanic eruption. The gas sulphur dioxide has special property which allows it to reflect the sunlight away from the earth. Sulphur dioxide also reflects other volcanic gases to the atmosphere, hence ensure cooling at the volcanic site.

explanation:

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
