Do you think of a desert as a hot,dry place where sand stretches as far as you can see?The Sahara in North Africa is like that,but most deserts are not.All deserts are dry,but some deserts are very cold.Plants and animals live in most deserts.People have learned to live in deserts all over the world.
Most deserts form because of air movements over the planet.Masses of dry air create deserts.For example,deserts can form where air currents go over mountains.Water gets squeezed out of the air as it passes over the mountains,and a desert forms on the other side of the mountains.Deserts can also form along some seacoasts where there are currents of cold water.There are two main bands of desert areas,one north of the equator and one south of the equator.The equator is an imaginary line that goes around Earth’s middle.
好的,我的翻譯也是僅供參考
你認(rèn)為沙漠是個(gè)很熱,很干燥,滿眼都是沙子的地方么?北非的薩哈拉沙漠是這樣的,但是大部分沙漠都不是.所有的沙漠都很干燥,但是有些沙漠是寒冷的.植物和動(dòng)物都可以住在沙漠里,世界各地的人們也已經(jīng)學(xué)會(huì)住在沙漠.
大部分沙漠的來(lái)源是地球表面的空氣運(yùn)動(dòng),干燥空氣制造了沙漠.比方說(shuō),沙漠可以來(lái)自于風(fēng)搬運(yùn)了山上的沙土.水被從空氣中凝結(jié)出來(lái)被山遮擋,另一面就是沙漠.沙漠也會(huì)在一些寒冷的沿海地區(qū)有冷水的中央地帶出現(xiàn).一般都有一個(gè)區(qū)域在北邊一個(gè)在南邊.那個(gè)區(qū)域一般都在大陸的中間.
