地球表面的海洋,约占地表总面积的71%。正因如此,从太空回望我们的家园,是一颗蓝色的星球。其实,海洋是海和洋的总称,二者还是有区别的。地球表面分布着4个大洋,它们分别是:太平洋北起亚洲和北美洲之间的白令海峡,南抵南极大陆,东起美洲的巴拿马运河,西迄亚洲中南半岛的克拉地峡。面积约占世界大洋的一半。
The ocean on the surface of the earth accounts for about 71% of the total surface area of the earth’s surface. It is precisely for this reason that looking back at our home from space is a blue planet. In fact, the ocean is the general name of the sea and the ocean. There is a difference between the two. There are four oceans on the surface of the Earth: the Bering Strait between Asia and North America in the Pacific Ocean, the Antarctic continent in the south, the Panama Canal in the Americas in the east, and the Krassian Gorge in the West from the Asian Peninsula in Asia. The area accounts for about half of the world’s oceans.
