Elaboration
An interaction is a kind of action that occurs when two or more objects have an effect on one another. The interaction may be direct or indirect. In a direct interaction, A has a direct effect on B. An example of a direct interaction is wolves preying on elk. In an indirect interaction, A has an effect on B that affects C. For example, ladybugs have an indirect effect on plants because they eat aphids.
- Key questions about interactions:
- How do the four spheres of the Earth interact?
- How can understanding the interactions of Earth’s spheres help us prepare for natural disasters?
