【题目】关于黄河描述错误的是

A.黄河发源于青海省,从山东省流入渤海

B.黄河下游流经黄土高原,水土流失严重,成为世界上含沙量最大的河流

C.黄河塑造并灌溉了宁夏平原和河套平原

D.黄河流经宁夏、内蒙古和山东等省,低纬流向高纬的河段易形成凌汛。

【答案】B

【解析】

黄河发源于青藏高原的巴颜喀拉山脉,注入渤海。全长5464千米,是我国的第二长河。从地图上看,黄河干流像一个巨大的“几”字,年径流量只有60多亿立方米,约为长江的1/15,而且70%-80%集中在夏秋季,要支流:洮河、湟水、汾河、⑥渭河。

黄河源自青藏高原的巴颜喀拉山,流经青海、四川等9省区,从山东注入渤海,全长5464千米,黄河中游流经黄土高原,由于水土流失严重,河流泥沙大增,成为世界含沙量最大的河流。黄河在宁夏和内蒙古塑造并灌溉了宁夏平原和河套平原,使其成为“塞上江南”,流经宁夏、内蒙古和山东等省,低纬流向高纬的河段在冬季的封河期和春季的开河期都有可能发生凌汛。故选:B
