Planet A is an outer planet, and planet B is an inner planet. Inner planets rotate slowly, so they take more time to complete a rotation. Outer planets rotate faster, so they take less time to complete a rotation. Which ideas did you include in your answer? Check all that apply. Inner planets rotate slower. Outer planets rotate faster. Inner planets take more time to complete a rotation. Outer planets take less time to complete a rotation. Planet A is an outer planet. Planet B is an inner planet.

Planet B is an inner planet.

Explanation:

Taking as a model our Solar System we know the following:

The inner planets (such as our Earth, Mercury, Venus and Mars), rotate on their own axis (also called spin) slower than the outer planets (such as Jupiter, Saturn, Uranus and Neptune). This is because of the Sun's huge gravitational field, which holds the nearest planets tightly as they make their revolution around the star.

However, inner planets complete one orbit around the Sun faster than the outer planets, for this same reason (due to their proximity to the Sun's gravitational field).

Hence, if Planet A is an outer planet, and Planet B is an inner planet, then Planet A will spin (rotate on its own axis) faster than Planet B.
