C. 遭受暴雨襲擊,科考站被淹沒(méi)
D. 冰雪覆蓋冰隙、冰溝,隨時(shí)有可能吞沒(méi)考察隊(duì)員
【答案】C
【解析】本題考查極地的自然環(huán)境特點(diǎn)。極地酷寒,多狂風(fēng),降水稀少。夏季出現(xiàn)極晝時(shí),太陽(yáng)總在地平線(xiàn)上,但太陽(yáng)高度小,陽(yáng)光嬌弱無(wú)力,根本無(wú)法驅(qū)散冰原上的寒氣。冬季出現(xiàn)極夜時(shí),長(zhǎng)夜漫漫,暴風(fēng)雪在冰原上不停地咆哮。故A不符合題意;1680年8月,科學(xué)家在蘇聯(lián)東方站曾測(cè)得-88.3℃的極端最低氣溫?崃业暮洌∽〗o隊(duì)員留下無(wú)情的凍傷印記。故B不符合題意;極地酷寒,多狂風(fēng),降水稀少,在南極考查不會(huì)遭受暴雨襲擊。故C符合題意;南極洲98%的陸地為冰雪所覆蓋,縱橫交錯(cuò)的冰隙,冰雪覆蓋的冰溝隨時(shí)有可能吞沒(méi)考察隊(duì)員。故D不符合題意。故選C。
