【題目】讀“某地區(qū)等高線地形圖(海拔:米)”,回答下列問題。

(1)寫出圖中字母所代表的地形部位名稱:

A ,B , C

(2)D、E圖中兩地中可以發(fā)育成河流的是 ,判斷理由

(3)圖中的等高距是 米,甲、乙兩山山頂?shù)南鄬Ω叨仁?/span> 米。

(4)甲山在乙山的 方向,兩地之間的實地直線距離約 米。

【答案】(1)陡崖; 山峰(山頂); 鞍部。

(2)E; 該地等高線的彎曲部分向高處凸出,地形為山谷有利于水流匯成河流。

(3)100米; 58米。 (4)東北; 3750

【解析】(1)由圖可知,圖中A有多條等高線重合在一起,是陡崖地形;B處是山峰地形,C處是鞍部地形。

(2)D、E圖中兩地中可以發(fā)育成河流的是E處,因為這里是山谷地形,有利于形成河流。

(3)由圖可知,圖中的等高距是100米,甲、乙兩山山頂?shù)南鄬Ω叨仁?78-620=58米。

(4)圖中既沒有指向標,也沒有經(jīng)緯網(wǎng),可通過“上北下南、左西右東”判斷方向,所以甲山在乙山的東北方向,由圖中比例尺可知,兩地之間的實際直線距離約為3750米。
