At the early formation period, like Earth, collisions with debris from the solar system formation, as in asteroids and meteoroids caused the initial "shaping" or scarring of the surface. Mars was believed to have an atmosphere and water like Earth for a short period. I believe that period to have lasted only a billion years, during which the surface of Mars was smoothed a little before the atmospheric loss enabled meteor damage once again. Mars does have a very thin atmosphere. The effects of ongoing meteor and wind erosion will change the planet's appearance.
The main factors shaping the surface of Mars today are wind erosion, impacts from meteorites, and seasonal changes in the polar ice caps. These processes continue to alter the landscape on Mars over long periods of time.

Mars has evidence of erosion by water, including river valleys, channels, and minerals formed in the presence of water. Mars once had liquid water flowing on its surface, shaping the landscape over time.
The main process responsible for shaping the surface of the land is erosion, which includes the wearing away of rock and soil by water, wind, and glaciers. Erosion is a natural process that can create various landforms such as valleys, canyons, and coastlines over long periods of time. Additionally, weathering, which breaks down rocks into smaller particles, also contributes to shaping the land surface.
The wind erosion is mostly responsible for the shape of planet Mars as well as the space debris that impact Mars.
Water is believed to have formed channels on the surface of Mars long ago. Evidence such as dried-up riverbeds, erosion patterns, and mineral deposits indicate that water once flowed on the planet, shaping its surface.
No, erosion by water and ice is the dominant agent for shaping much of the Earth's surface over long periods of time. While earthquakes can cause sudden changes in topography, erosion is the primary force responsible for shaping the Earth's landscapes.
Rocks and The Mars Rovers are on the surface of the planet Mars.
Mars is sandy.
100% of the surface of mars is land. There is no surface water on mars
Mercury has virtually no atmosphere. Mars has an atmosphere that is much thinner than Earth's, but still thick enough for wind to be important in shaping its surface.
