A.纬度高低

B.地形地势

C.海陆分布

D.人类活动

答案

答案:B

地形对气候的影响主要表现为随着海拔的升高气温降低,降水也会出现相应的变化。在地球表面,随着海拔升高气温降低,每升高100米,大约降低0.6℃。井冈山山顶海拔1597米,比平地高,所以气温较低。所以本题选择B选项。

     Death Valley is one of the most famous deserts in the United States, covering a wide area with its alkali

sand. Almost 20 percent of this area is well below sea level, and Badwater, a salt water pool, is about 280

feet below sea level and the lowest point in the United States.

     Long ago the Panamint Indians called this place “Tomesha”- the land of fire. Death Valley's present

name dates back to 1849, when a group of miners coming across from Nevada became lost in its

unpleasantness and hugeness and their adventure turned out to be a sad story. Today Death Valley has

been declared a National Monument and is crossed by several well-marked roads where good services can

be found easily. Luckily the change created by human settlement has hardly ruined the special beauty of this

place.

     Here nature created a lot of surprising scenes, almost like the sights on the moon, ever-changing as the

frequent wind moves the sand about, showing the most unusual colors. One of the most astonishing and

colorful parts of Death Valley is the Devil's Golf Course, where it seems hard for one to tell reality from

dreams. Sand sculptures stand-on a frightening ground, as evening shadows move and lengthen.
