Presents a brief introduction to the world's oceans, in simple text with illustrations, including information on the size, climate, and plant and animal life of the Atlantic, Pacific, Indian, and Arctic Oceans.
The subzero temperatures and glacial conditions to which the polar regions of the Earth are often subject would make it difficult for many of us to survive there, yet life is present in both the Arctic and Antarctic. Journey alongside some of the early expeditions and will learn about the conditions and life that comprise the polar ecosystems.
