Death Valley is the hottest and the driest place in North America.②Death Valley isn’t an easy place to live in. It gets less than two feet of rain a year and it’s hot, too. In July, temperature often gets over 46℃. Even a lakethere has turned into salt crystals（晶体）. But it is cold at night. When it gets cold enough, the water on the ground will turn into thin ice. Then the strong wind—like a large hand—can move the rocks along the icy ground. That is why the rocks can “walk” on their own in Death Valley.③The weather condition in Death Valley is terrible, but nothing can stop plants and animals from making it their home. People have found more than 1,000 kinds of plants there. It also has 51 kinds of mammals（哺乳动物）, 6 kinds of fish, and more than 300 kinds of birds. The animals aren’t all small, either.④Finding water is the biggest challenge for anything that lives here. To survive, some plants’ roots（根部）can go fifty feet under the ground to find water. Kangaroo rats（更格卢鼠）get the water they need from flowers.⑤Death Valley really makes a lot of surprise!31. (  ) Why can the rocks “walk” on their own in Death Valley?A.
