问题 选择题

假设地球自东向西自转,地球上下列地理现象中不会发生变化的是(  )

A.日、月东升西落现象

B.南半球河流一般右岸多沙滩

C.昼夜现象

D.120°E的地方时早于90°W

答案

答案:C

题目分析:

由于地球自西向东自转,才产生了日、月东升西落的现象。若地球自转方向改变为自东向西,则人们看到的现象会是日月西升东落。A会发生变化。自转方向改变,则地转偏向力的方向也改变,变成北半球向左偏,南半球向右偏。向右偏,则右岸被侵蚀,左岸多沙滩,B会发生变化。无论地球怎样自转,昼夜现象都存在,是不会改变的。所以选C。自转方向相反了,那么西边的时刻就比东边早了,D也会发生变化。
