内容简介：
This high-interest science series takes readers into an exciting world of extremes. Each book focuses on one of Earth's most challenging environments: the hottest deserts, highest mountains, deepest oceans, and coldest glaciers. Readers get to investigate each habitat just as a real-life explorer would. The books discuss survival equipment for exploring extreme regions - what to wear, what to bring, and how to get there; landscape and landforms; weather and climate; and the ways plants, animals, and people have adapted to live in extreme habitats.
