When the sun shines on a pla, the pla’s surface reflects some of the sunlight back into space. Some other sunlight gets absorbed and warms the pla. Lightcolored surfaces, such as white ice caps, reflect more sunlight than dark surfaces do. By contrast, dark surfaces absorb more of the sunlight, which makes them get hotter. Scientists who have pared pictures of Mars taken by satellites in the 1970s to images taken more recently have noticed that the Red Pla’s surface looks different than it used to. In some areas, the landscape looks much darker, while in others, it looks lighter. On the whole, the surface of Mars— especially in the pla’ s southern hemisphere— has grown darker over the past 30 years.

That exposed darker rocks that had been covered with dust. The darkening of Mars has caused the pla to get warmer, a new study suggests. Scientists calculated how much more sunlight and heat Mars absorbs now. They pared that to how much it absorbed in the late estimate that the pla’s atmosphere is almost 1℃ warmer, on average, than it was 30years ago. Some areas of mars have warmed more than average. For example, the pla’s south pole may be 4℃ warmer than it was in the late 1970s. 55. 30 years ago, the surface of Mars looked________.
