【題目】(原創(chuàng))小明列舉了我國南極科學(xué)考察隊在南極考察時可能遇見的危險,其中不可信的是( )
A. 暴風(fēng)雪在冰原上不停地咆哮,使人暈眩迷途
B. 酷烈的寒冷,給隊員留下無情的凍傷印記
C. 遭受暴雨襲擊,科考站被淹沒
D. 冰雪覆蓋冰隙、冰溝,隨時有可能吞沒考察隊員
【答案】C
【解析】本題考查極地的自然環(huán)境特點。極地酷寒,多狂風(fēng),降水稀少。夏季出現(xiàn)極晝時,太陽總在地平線上,但太陽高度小,陽光嬌弱無力,根本無法驅(qū)散冰原上的寒氣。冬季出現(xiàn)極夜時,長夜漫漫,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)東方站曾測得-88.3℃的極端最低氣溫。酷烈的寒冷,住住給隊員留下無情的凍傷印記。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,縱橫交錯的冰隙,冰雪覆蓋的冰溝隨時有可能吞沒考察隊員。故D不符合題意。故選C。
