问题 判断题

(12分)读下图回答下列问题。

(1)甲乙丙丁四座山峰,海拔最高的是     ,该山峰海拔为      米。(2分)

(2)甲山峰位于乙山峰的     方向,两山峰的实际距离约为     千米。(2分)

(3)该地区地形以     为主,地势                               。(2分)

(4)E点所在的地形部位是     ,F点所在的地形部位是     。(2分)

(5)M点所在的地形部位是     ,N点所在的地形部位是     。(2分)

(6)①和②为两条登山路线,你选择哪条?请说明理由。(2分)

答案

(1)甲 952

(2)正东  6

(3)山地 东北高,西南低

(4)鞍部 陡崖

(5)山谷 山脊

(6)选①的理由是:等高线稀疏,坡度缓,省力气.选②的理由是:路途近,省时间.

题目分析:

(1)海拔是地面某一个地点高出海平面的垂直距离,结合图示得知:海拔最高的是甲处,海拔高度为952米.

(2)结合指向标得知:甲山峰位于乙山峰的正东方向;根据比例尺=图上距离/实地距离得出,两山峰的实际距离=5×200000=1000000厘米=10千米.

(3)结合图示得知:该地区的地形以山地为主,地势是东北高,西南低.

(4)E点所在的地形部位是鞍部(两山顶之间相对低洼的部位为鞍部),F点是陡崖(几条海拔不同的等高线重合处为陡崖).

(5)M点为山谷(等高线向海拔高处凸为山谷);N点为山脊(等高线向海拔低处凸为山脊).

(6)两条登山线路各有利弊,选①的理由是:坡度缓,省力气;选②的理由是:路途近,省时间.
