【題目】讀等高線(單位:米)地形圖,完成下列各題。

1P地為一村莊,圖中最高點與P地的相對高度最可能的是(  )

A. 300 B. 400 C. 500 D. 600

2圖中①處的陡崖高度可能是(  )

A. 200米 B. 300米 C. 400米 D. 500米

【答案】

1C

2A

【解析】請在此填寫整體分析!

1根據(jù)圖示:等高線地形圖等高距為100米,圖中P村莊的海拔:0米<P<100米,海拔最高處山地海拔:500米<山頂<600米。所以圖中最高點與P地的相對高度:400米<H<600米。所以本題選擇C選項。

請在此填寫小題的解析!

2讀圖可知等高距為100,此時陡崖底部的取值范圍為(300,400),陡崖頂部的取值范圍為(400,500),利用交叉法可知陡崖相對高度的取值范圍為(100,200),故不會超過200米。
