【题目】读“某地区等高线地形图(海拔:米)”,回答下列问题。

(1)写出图中字母所代表的地形部位名称:

A ,B , C

(2)D、E图中两地中可以发育成河流的是 ,判断理由

(3)图中的等高距是 米,甲、乙两山山顶的相对高度是 米。

(4)甲山在乙山的 方向,两地之间的实地直线距离约 米。

【答案】(1)陡崖; 山峰(山顶); 鞍部。

(2)E; 该地等高线的弯曲部分向高处凸出,地形为山谷有利于水流汇成河流。

(3)100米; 58米。 (4)东北; 3750

【解析】(1)由图可知,图中A有多条等高线重合在一起,是陡崖地形;B处是山峰地形,C处是鞍部地形。

(2)D、E图中两地中可以发育成河流的是E处,因为这里是山谷地形,有利于形成河流。

(3)由图可知,图中的等高距是100米,甲、乙两山山顶的相对高度是678-620=58米。

(4)图中既没有指向标,也没有经纬网,可通过“上北下南、左西右东”判断方向,所以甲山在乙山的东北方向,由图中比例尺可知,两地之间的实际直线距离约为3750米。
