三地同学共同开展一个“影子长度”的探究学习活动,他们在当地时间10:00—14:00每隔一小时测量一根1米长的杆的影子长度,并将所得数据绘制成图。下图为6月22日三个地区同学所提供的观测结果。回答1~2题。

小题1:甲、乙、丙三地纬度由低到高的顺序是  (   )

A.甲、乙、丙

B.甲、丙、乙

C.乙、甲、丙

D.丙、乙、甲小题2:关于乙地此时气候特征的描述,最可能出现的是  (   )

A.一年中气温较高、降水较多的季节

B.一年中降水较少、草木枯黄的季节

C.一年中气温较低、降水较多的季节

D.一年中降水较多、作物生长旺盛季

答案

小题1:C

小题2:B

小题1:根据正午影子最短的长度和朝向判断纬度高度。6月22日太阳直射北回归线,图中甲位于北回归线;丙距离北回归线较近,位于北回归线以北地区,乙地位于南半球,在赤道和南回归线之间。所以甲、乙、丙三地纬度由低到高的顺序是乙、甲、丙。所以本题选择C选项。

小题2:乙地纬度为21°34′S,60°W,位于南美洲热带草原气候区。此时为北半球夏季,其为一年中降水较少、草木枯黄的季节。所以本题选择B选项。
