Which of the following best describes the formation of the solar system?
The sun ejected rocky material which later went on to form the planets.
A rotating disk of gas and dust was drawn together by the force of gravity.
One very large planetary body broke apart into several smaller planets.

The data table provides information on the distance and period of orbit for the inner planets.
Based on the pattern in the data, we can predict that the period of Mars’ orbit will be–
less than 88 days.
between 88 and 224.6 days.
