介绍撒哈拉沙漠英语
介绍撒哈拉沙漠英语Sahara desertTHE Sahara desert is the world’s largest desert area.It extends from the Africa’s Atlantic Ocean side to the Red sea and consists of the countries of Morocco,Algeria,Tunisia (突尼斯),Libya,Egypt,Mauritania (毛里塔尼亚),Mali,Niger （尼日尔）,Chad（乍得）,and Sudan.It is about 5,200 miles long.Overall,the Sahara desert covers 3,500,000 square miles.The geography of the desert is varied.In the west,the Sahara is rocky with varied elevation.It does contain underground rivers,which sometime penetrate the surface,resulting in oases.The central region of the Sahara has more elevation than the other areas,with peaks such as Tahat.Even though the area lacks rainfall,these peaks are snowcapped during the winter.The eastern part of the Sahara,the Libyan desert,is dry with very few oases. The Sahara’s climate is very hot and dry.Although it is very hot during the day,it does become cold at night.The Sahara used to be a fertile area in which elephants,giraffes and other animals grazed.It is estimated that in 4,000 BC,the climate began to get drier.The fertile landscape dried up and the desert widened,creating the form that appears today.(SD-Agencies)。
撒哈拉沙漠简介
历史沿革
● 依据撒哈拉沙漠里的岩画内容，可划分它们为几个时期： ● 史前时期 ● 史前时期在更新世的前后。撒哈拉当时并未很干燥，而是广阔的河流冲积平原。这阶段没有发现
形成原因
● 2014年9月22日，中国科学院大气物理研究所最新的研究显示：大约700万年到1100万年前，特 提斯海的收缩导致非洲撒哈拉沙漠的形成，这一观点推翻了撒哈拉沙漠形成于第四纪（大约300 万年以前）的传统观点。
● 一般认为撒哈拉沙漠的形成时代不会早于第四纪。大量的地质记录显示第四纪冰期开始的时候撒 哈拉出现了显著的干旱。撒哈拉的干旱程度主要受非洲夏季风的影响。
● 撒哈拉沙漠由两种气候情势所主宰︰北部是干旱副热带气候，南部是干旱热带气候。干旱副热带 气候的特征是每年和每日的气温变化幅度大，冷至凉爽的冬季和炎热的夏季至最高的降水量。
● 年平均日气温的年幅度约20℃（68℉）。平均冬季气温为13℃（55℉）。夏季极热。利比亚的阿济济耶（Al-Aziziyah） 最高气温曾达到创纪录的58℃（136℉）。年降水量为76公釐（3吋），虽然降雨变化极大，多数降水发生在12～3月期间。 另一降水高潮是8月，以雷暴形式为其特征。
撒哈拉沙漠地图
名称由来
● “撒哈拉”这个名称来源于阿拉伯语ءارحصال，是从当地游牧民族图阿雷格人的语言引入的，在其 语言中就是“沙漠”的意思。这块沙漠大约形成于250万年以前。
● 在上一个冰河时期，撒哈拉还不是一个沙漠，气候类似于东非，在沙漠地带发现了大约有3万幅古 代的岩画，其中有一半左右在阿尔及利亚南部的恩阿杰尔高原，描绘的都是河流中的动物，如鳄 鱼等。
