How might volcanic eruptions change the flow of energy on earth?

Answers

Answer:

It causes global warming due to emission of carbondioxide gas.

Explanation:

Volcanic eruptions change the flow of energy on earth by emitting gases such as carbondioxide and sulfur dioxide gases. Volcanic gases like sulfur dioxide is responsible for global cooling by reflecting solar radiation back to the space, while on the other hand, carbon dioxide emitted from volcanoes, has the ability to promote global warming by blocking solar radiation. If the amount of carbondioxide gas is higher as compared to sulfur dioxide gas so global warming occurs.
