下图为海洋中的一个小岛,a和b分别表示两条纬线,回答小题。

小题1:若a和b分别表示赤道和北回归线,那么关于甲、乙两地气候和自然景观说法正确的是

A.甲地的气候可能是热带草原气候

B.乙地的气候可能是热带沙漠气候

C.甲地的自然景观可能是热带雨林

D.乙地的自然景观可能是亚热带常绿硬叶林小题2:若a和b分别表示北纬40°和北纬60°,岛屿以东不远就是一块大陆,

A.甲地可以种植甘蔗

B.乙地主要从事粮食种植

C.岛屿的最高峰能终年看到积雪

D.仅考虑盛行风向,甲地沿岸更适合建设港口

答案

小题1:C

小题1:D

题目分析:

小题1:若a和b分别表示赤道和北回归线,判断图示岛屿位于北半球的低纬地区,故受东北信风影响,故甲位于东北信风的迎风坡,降水量丰富,而形成热带雨林气候,而乙位于东北信风的背风坡,故降水量较少,而形成热带草原气候。故选C。热带沙漠气候热带沙漠气候出现在副热带高压带及信风带的大陆西岸和大陆内部。亚热带常绿硬叶林是亚热带地中海气候的植被类型分布在30°-40°的大陆西岸。

小题2:若a和b分别表示北纬40°和北纬60°,则该岛屿位于北半球的中纬度地区,该岛屿受盛行西风影响,形成温带海洋性气候,不适宜甘蔗种植,故乙位于盛行西风的迎风坡,降水量丰富,故可发展种植业;该岛屿夏季气温20°C以上,而该山地不到3000米,故山顶不可能有终年冰川,C错误。受盛行西风影响,故甲位于背风坡,风浪较小,故选D项。

点评:本题难度适中,以不同纬度定位不同的地理位置然后根据所学地理知识进行综合分析。解答时要求学生能准确进行空间定位,然后结合纬度带、气压带、地形、盛行风向等进行分析。
