They are found in the Arctic, where the weather is extremely cold, dry and windy. Trees cannot grow in tundras, but there are many low plants. The Arctic tundra has average temperatures of –12 ºC to –6 ºC. This means that the top layer of soil, called the permafrost, is almost always frozen. In winter, the permafrost is covered with a thick layer of snow, and no plants are visible. In summer, there are 24 hours a day of sunlight, and the surface of the permafrost melts. Wildflowers appear everywhere. Many animals live in the Arctic tundra, including Arctic foxes, polar bears, caribous and snow geese. Unfortunately, as a result of global warming, temperatures are rising. This is causing the permafrost to melt. The Arctic tundra is in danger. 1 Read the text and circle the correct word. a.
