if you are think sand would be a layer yes mars is covered with red sand
cos it is
Because Earth is covered with water it looks blue. Mars is covered in red dust so it looks red.
mars is rocky, red , dry, and mostly covered with iron rich dust.
mars, and its actually an orangish hue.
Mars is red because the atmosphere scatters light in a way that causes the light to appear red, and because the surface is covered in red dust
The short answer to "why is Mars red" is that the planet is covered in rust. Iron oxide to be exact. The iron oxide is simply a dust that covers the entire surface in varying depths. That dust is picked up by wind and carried into the atmosphere where it reflects the red part of the light spectrum and, viola, Mars is the Red Planet.
Mars is red because its top layer is composed of mostly iron oxide (rust). The atmosphere appears red because the wind picks up the red dust and carries it.
Some scientists believe that Mars is red due to rocks being rusted by water that once flooded the planet.

Mars has a surface which is covered in red-orange dust.The dust contains oxides of iron. Rust is made of iron oxides.So, it's basically just rust. It's rusty dust.That's the scientific answer.
Its the hot red dust already on Mars which is blown in the atmosphere
