【題目】下列說法錯誤的是(

A.等高線上標(biāo)注的高度是海拔

B.等高線越稀疏,坡越陡;等高線越密,坡度越緩

C.同一條等高線上海拔數(shù)值相等

D.在分層設(shè)色地形圖上,綠色表示平原

【答案】B

【解析】

根據(jù)在等高線地形圖上,等高線閉合且等高線數(shù)值中間高四周低則為山頂;兩山頂之間相對低洼的部位為鞍部;等高線閉合且等高線數(shù)值中間低四周高則為盆地;等高線向海拔低處凸為山脊;等高線向海拔高處凸為山谷;幾條海拔不同的等高線重合處為陡崖。等高線密集表示坡陡,等高線稀疏表示坡緩,進行分析解答。

等高線上標(biāo)注的高度是海拔,故A正確;

等高線越稀疏,坡越緩;等高線越密,坡度越陡,故B錯誤;

同一條等高線上海拔數(shù)值相等,故C正確;

在分層設(shè)色地形圖上,綠色表示平原,故D正確。

故選:B
