(2)66.5°N、23.5°N、23.5°S

(3)AE、C

【解析】

试题分析:

(1)从上图可以看出,因为地球的中间,也就是赤道附近,有太阳直射,所以气温高,而在地球的两极,常年太阳是斜射的,甚至有些地方几个月时间太阳位于地平线以下,所以气温很低,而位于中间的地方,四季变化大,所以是温带;那么五带的划分自北向南分别是北寒带、北温带、热带、南温带、南寒带.

(2)太阳的直射是位于南北回归线之内,所以南北回归线是热带与温带的分界线,而在南北极圈内有极昼极夜现象,所以南北极圈是温带与寒带的分界线,由上图可知,的纬度数是66.5°N,的纬度数是23.5°N,的纬度数是23.5°S.

(3)五带中,北寒带和南寒带都有极昼极夜现象,只有热带有太阳直射,其余四个带都是没有的.
