Mars also has a thin but active atmosphere with clouds, weather systems, and winds that erode the surface. There are some striking differences. Second, since the surface has not been recycled by plate tectonics, it provides a record of Mars stretching back to the late heavy bombardment. Finally, dust and wind dominate the erosion on Mars, with some dust storms reaching global scales. You will explore some of the unique geological features on the surface of Mars, starting with two famous, large objects and dominant global features, and ending with high-resolution images at a much smaller scale.
Procedure Using the appropriate images linked in the sections below, answer the following questions.
This composite map of Mars generates images from the Viking orbiter for display. It is surmounted by a complex summit caldera, and surrounded by a prominent scarp several kilometers high. Valles Marineris is a rift valley formed when the Martian crust cooled. Recall pictures you have seen of the Grand Canyon.
