Which of the following is suggested by the flow patterns found on the surface of Mars and the number of craters on top of them?

B)The climate on Mars was different billions of years ago.
C)Volcanism is occurring on Mars.
D)The polar caps are made of liquid water.

Question

Quizplus · Accepted Answer

The flow patterns and crater distribution suggest that the climate on Mars was different billions of years ago, possibly indicating the presence of liquid water on the surface at that time. This is supported by other evidence such as the presence of dried-up riverbeds and canyons, as well as the composition of mineral deposits found on the planet. Therefore, option B is the best choice. Option A is incorrect because there is currently no evidence of liquid water existing on the Martian surface. Option C is also incorrect because although there is evidence of volcanic activity in the past, there is no evidence of ongoing volcanism. Option D is incorrect because the polar caps are mostly made of frozen water and carbon dioxide.
