题目内容

【题目】某课外活动小组计划开展野外考察活动,请根据图1、图2完成下列任务

(1)该图中最高山峰的海拔是米,地形类型属于
(2)从图1可知,李庄在吴庄的方向,如测得李庄到山顶B的直线距离为2.5厘米,吴庄到山顶B的直线距离为2厘米,如果活动小组翻过山顶B,两村间最少要走千米。
(3)根据李庄和吴庄所处的位置来看,更可能遭受泥石流威胁的是庄。
(4)俗话说“上山容易,下山难”。如要为了观察本区的全貌,翻过山顶,课外活动小组应该选择图中甲、乙中的线路,从庄出发,宿营地点应定在图中A、B、C中的点。
(5)如考察活动途中遇到泥石流,图2中 ①和②两种逃生方向正确的是

【答案】
(1)263;丘陵
(2)北偏西;9
(3)吴
(4)甲;吴;C
(5)①
【解析】读图分析可知:(1)海拔是地面某一个地点高出海平面的垂直距离。从图中可以看出,该图中最高山峰的海拔是263米,该地形类型属于丘陵。(2)依据指向标判定方向,从图1可知,李庄在吴庄的北偏西方向。由比例尺=图上距离÷实地距离,可得实地距离=图上距离÷比例尺。如测得李庄到山顶B的直线距离为2.5厘米,则李庄到山顶B的实地距离为2.5×2=5千米;吴庄到山顶B的直线距离为2厘米,则吴庄到山顶B的实地距离为2×2=4千米;由此可知,如果活动小组翻过山顶B,两村间最少要走9千米。(3)图中吴庄位于山谷处,山谷处易形成河流,因此,吴庄更可能遭受泥石的流威胁。(4)从图中可以看出,B山顶高,可以观察本区的全貌;甲路线中,从李庄到山顶比从吴庄到山顶等高线稀疏,比较容易下山。因此,为了下山易,为了观察本区的全貌,翻过山顶,课外活动小组应该选择图中甲、乙中的甲线路,从吴庄出发;宿营地点应定在图中A、B、C中的C点,因为C处地形平坦,A为山顶,B为陡崖,不适宜宿营。(5)如考察活动途中遇到泥石流,应朝着垂直于泥石流的方向逃生;由此可判定,图2中①和②两种逃生方向正确的是①。
所以答案是:(1)263;丘陵;(2)北偏西;9;(3)吴;(4)甲;吴;C;(5)①。
