How does greenhouse effect work?

How does the greenhouse effect since work on MARS?

• The greenhouse effect, which heats a planet's surface above the predicted equilibrium surface temerature for the planet without an atmosphere, is far less effective on Mars than on the Earth. Why is this? - The Martian atmosphere contains no gases that can absorb solar radiation. - The Martian surface temperature is very low and this reduces the effectiveness of the greenhouse effect. - The Martian atmosphere is very thin and traps less infrared radiation from the surface - There is less energy conducted upward from the Martian interior to the surface of Mars because of the thickness of its crust compared to that of the Earth.

• Answer:

  The Martian atmosphere is 100 times thinner than on Earth.
