Question

What sphere caused the event?
What are the effects of the event on one or more spheres? What are the global implication of the event?

Answer 1

Explanation:

An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres. This two-way cause and effect relationship between an event and a sphere is called an interaction. Interactions also occur among the spheres.
