When we examine the structures of the other terrestrial planets in our solar system, we see that their structure is similar to earth’s. why do you think this is the case?

Terrestrial planets are earth-like planets due to the similarities they share with the earth.

Explanation:

Four planets in our ecosystem between the sun and asteroid belt, Mercury, Venus, Mars, and earth are called terrestrial planets. They are similar in terms of composition and structure. They are composed of silicate rocks and metals and thus have a rigid planetary surface.

In contrast to the terrestrial planets, Jupiter, Saturn, Uranus and Neptune commonly called the ‘gas giants’ are composed of hydrogen, helium, water, and other heavier elements and thus lack a rigid planetary surface.
