Blowing in the Wind : Connections between Wind , Climate , and Biomes
氣流的吹動 : 和風、氣候及生物社會間的相關

Why is one area of the earth’s land syrface a desert , another a grassland , and another a forest?The general answer is differences in climate .

為何地球表面上會有沙漠、草地、森林，普遍的答案是因為不同的氣候。

Wind is an important factor in the earth’s climate . Without wind , the tropics would be unbearably hot and most of the rest of the planet would freeze .

風是地球氣候中的重要因素，沒有風，族會無法接受熱和環境的凍結。

Winds also transport nutrients from one place to another . For example , winds carry dust rich in phosphates and iron across the Atlantic from the Sahara Desert in Africa . These deposits help build agricultural soils in the Bahamas and supply nutrients for plants in upper canopies of rain forests iron Brazil . Dust blown from China’s Gobi Desert deposits iron into the Pacific Ocean between Hawaii and Alaska . The iron stimulates the growth of phytoplankton , the minute producers that support ocean food webs .

風也可以將營養物從某地運輸至另一地方，例如：風可以運送沙土，其中含磷、鐵，從非洲撒哈拉沙漠到大西洋。這沉積物可幫助農藝土壤的建造，及提供營養物給巴西上部雨林的植物。沙土從中國的戈壁沙漠沉積鐵至平靜的海洋，在夏威夷州和阿拉斯加州之間。鐵可促進浮游植物群落的生長。這些的生長可支持海洋食物網。


重點：

說明風對地球生物的重要性，雖然沙塵暴對地球有壞處，但對於戈壁沙漠而言，風和沙土可幫助植物生長，對於撒哈拉沙漠來說，沙土可幫助農藝建造。
