【题目】下图为南半球经纬网示意图,读图回答下列各题。

1丁地的经度是(  )

A. 100°E B. 100°W C. 40°S D. 40°N

2甲、乙、丙、丁四地中纬度最高的是(  )

A. 甲地 B. 乙地 C. 丙地 D. 丁地

3甲、乙、丙、丁四地中既位于中纬度,又位于东半球的是(  )

A. 甲地 B. 乙地 C. 丙地 D. 丁地

4甲地位于乙地的(  )

A. 东南 B. 东北 C. 西南 D. 西北

【答案】

1A

2C

3D

4C

【解析】试题分析:

1】依据在经纬网上,若相邻两条经线的经度向东增大,就是东经,用符号E表示,若相邻两条经线的经度向西增大,就是西经,用符号W表示;若相邻两条纬线的纬度向北增大,就是北纬,用符号N表示,若相邻两条纬线的纬度向南增大,就是南纬,用符号S表示.读图分析可知,丁地的经纬度是100°E40°S.依据题意.

故选:A

2】纬度的划分是以赤道(纬线)为起始线,向北向南各分了90°.赤道以北是北纬,用“N”表示,赤道以南是南纬,用“S”表示.读图分析可知,甲、乙、丙、丁四地中纬度最高的是丙地(90°S),纬度最低的是乙地().依据题意.

故选:C

3】依据经纬度的判读,读图分析可知,图中甲点的经纬度是20°W40°N;乙点的经纬度是80°E;丙点位于南极点,纬度为90°S;丁点的经纬度是100°E40°N.南北半球的划分是以纬线即赤道为界,赤道以北为北半球,以南为南半球.南温带的纬度范围是23.5°S﹣66.5°S.由此可知,甲、乙、丙、丁四地中既位于南温带,又位于东半球的是丁地.依据题意.

故选:D

4】在经纬网地图上,用经纬网定方向,纬线指示东西方向,经线指示南北方向.读图分析可知,甲地位于乙地的西南方向.依据题意.

故选:C
