Compare photographs of the surface of the Earth and Mars. How are the planets similar and how are they different from each other?

There are even volcanoes on Mars, but no active ones. Also present: deserts, valleys, polar ice caps. There is also a distinctive feature of Mars, it consists in the presence of impact craters. There are no such impact craters on Earth, this is a divergence. There are light and dark areas on Mars. Light areas are called continents, and dark areas are called seas. Previously, it was assumed that liquid water exists in dark areas. But the opinion of the scientists was wrong. There are geological formations on the planet that are considered river deltas and channels. This is similar to the Earth.
