How much of Mars is covered by dust and rock?
Quick Answer
Mars is covered by a global layer of dust and broken rock, with dunes, regolith, and bare volcanic surfaces across much of the planet.
The Full Story
Mars is often called the Red Planet because its surface dust contains iron oxides, which give it a rusty color. Much of the ground is covered by regolith, a loose mix of dust and fragmented rock created by impacts and weathering. Winds can move this dust into dunes, dust devils, and global dust storms. In many places, especially on crater walls and ancient highlands, exposed rock shows that Mars once had a very different surface history.
