A.8844B.9244

C.12844D.2108

【答案】B

【解析】

海拔(绝对高度):地面某个地点高出海平面的垂直距离。地形:地表各种各样的形态、形状的总称。等高线:在地图上,把海拔高度相同的各点连接成的线。等高线之间互相平行,距离(即等高距、高差、相对高度)相等。等高距:等高线之间的距离(只能是相对高度)。同一图上的等高距是一个常数。等深线:在地图上,把海洋深度相同的各点连接成的线。等高线地形图:用等高线表示地面高低起伏的地图。分层设色地形图:彩色分层设色地形图上,绿色表示平原,黄绿色表示丘陵或山地,黄色或褐色表示高原,蓝色表示海洋。

相对高度是指任意两点之间的垂直距离,珠穆朗玛峰海拔8844米,死海海拔-400米,所以两地相对高度是9244=8844-(-400米);故选:B
