【題目】地理科學探索是正確認識地理現象和事物的途徑之一，一般包括“觀察發(fā)現﹣大膽假設﹣尋找證據（實驗驗證）”等過程。下列地理事件或理論最能體現上述探索過程的是（ ）
A.斯科特南極探險
B.魏格納的大陸漂移說
C.麥哲倫環(huán)球航行
D.中國發(fā)射北斗導航衛(wèi)星

【答案】B
【解析】大陸漂移假說是20世紀初魏格納提出的。大陸漂移假說認為，地球上原先只有一塊叫“泛大陸”的龐大陸地，被叫做“泛大洋”的廣袤海洋所包圍。大約兩億年前，泛大陸開始破裂，碎塊像浮在水上的冰塊一樣向外越漂越遠。距今大約兩三百萬年前，形成現在七大洲，四大洋的基本面貌。魏格納從地圖觀察大西洋兩岸凹凸吻合，由此猜測這里很早以前曾經連在一起，創(chuàng)立了大陸漂移說，并實地考察，尋找證據加以印證，最能體現“觀察發(fā)現﹣大膽假設﹣尋找證據（實驗驗證）”的探索過程。 故選B
