题目内容

【题目】等高线地形图,回答问题。

(1)已知甲、乙两山顶之间的图上距离为2厘米,则实际距离是 米。

(2)图中可能发育河流的地点是 处。(填序号)

(3)甲山顶与乙山顶的相对高度是 米。

(4)地形部位:

(5)图中等高距为 米.

(6)从还是登上甲山顶容易? 。理由是

(7)甲山顶位于乙山顶 方向。

【答案】

(1)10000

(2)

(3)170

(4)山谷 山脊 陡崖

(5)200

(6) 处等高线稀疏,坡度相对平缓。

(7)东北

【解析】

试题解析:

根据比例尺图上距离/实际距离,得:实地距离=图上距离/比例尺=2×500000=1000000厘米=10000米;

河流往往发源于山谷地带,故选择

(3)甲山的海拔是1150米,乙山的海拔是1320米,甲山比乙山低170米;

(4)A处为鞍部,位于两山顶之间,G处为陡崖,等高线重叠,DC线表示山脊,等高线向低处凸,EF线表示山谷,等高线向高处凸;

(5)每相邻两条等高线的海拔是400m,600m,所以它们之间的等高距是600-400=200(m);

(6)处等高线稀疏,坡度相对平缓

(7)地图上的方向有不同的表示方式.有的地图用指向标指示方向,指向标箭头的指向一般为北向.使用这种地图,要根据指向标来确定方向.可以判定图中甲山在乙山的东北方向.
