【题目】1月,一位从哈尔滨的游客从哈尔滨出发向南旅行,经北京、广州到海南岛,一路上他感到气温有很大变化,这主要是因为 ( )

A.南北方人的生活习惯不同B.各地所处的纬度不同

C.各地距海洋的远近不同D.各地的海拔高度不同

【答案】B

【解析】

根据气候复杂多样,是我国气候的主要特征之一;我国地域辽阔,地跨众多的温度带和干湿地区,加上我国地形复杂,地势高低悬殊,更增加了我国气候的复杂多样性;我国冬季南北气温差异大,南方温暖,而越往北气温就越低.夏季南北普遍高温,进行分析解答。

我国位于北半球,南北跨将近50个纬度。在冬季,太阳直射在南半球,对北半球来说,纬度越高,正午太阳高度角越低。我国北方地区正午太阳高度角比南方低,白昼短,得到太阳的光热少;1月,一位游客从哈尔滨出发向南旅,经北京、广州到海南岛。气温会越来越高。

故选:B
