The choices below describe four hypothetical planets. Which one would you expect to have the most features of erosion? (Assume the planets orbit a star just like the Sun and that they are all the same age as the planets in our solar system.)

Question

Quizplus · Accepted Answer

Planet A is the most likely to have the most features of erosion because it is the same size as Venus, which is a planet with a thick atmosphere that traps heat and causes erosion. Planet A is also the same distance from the Sun as Mars, which is a planet with a thin atmosphere that allows erosion to occur. Finally, Planet A has a rotation rate of once every 25 hours, which is similar to the rotation rate of Earth, which is a planet with a variety of erosional features.
