question 2\nwhich of the following explains how earth is a system?\nearth is in the boundary of the solar system.\nearth is the only planet with water.\nearth has four spheres that are separate and independent of each other.\nearth has four spheres that interact with each other.

Answer

Brief Explanations:

A system is a set of interacting or interdependent components forming an integrated whole. Earth has four spheres - the lithosphere, hydrosphere, atmosphere, and biosphere - which interact with each other. For example, water from the hydrosphere evaporates into the atmosphere, plants in the biosphere take in carbon - dioxide from the atmosphere and nutrients from the lithosphere. The first two options do not relate to Earth as a system, and the third option is incorrect as the spheres are not independent.

Answer:

Earth has four spheres that interact with each other.
