The atmosphere is a mixture of gases that surrounds a planet. The atmosphere becomes thinner and thinner from the surface until it gradually reaches space. Usually, the atmosphere blocks dangerous rays from the sun, and helps keep the surface warm. The atmosphere is also the place where weather takes place. In this tour we will look at what the atmosphere of Mars is made of, the layers of the atmosphere, and see if weather happens there.
