【題目】“太陽大,地球小,地球圍著太陽跑;星兒移,月兒轉(zhuǎn),地球自個兒也在轉(zhuǎn)!睋(jù)此完成下面小題:

1關(guān)于地球儀的說法,錯誤的是(  )

A.人們仿照地球的形狀,并按照一定的比例把它縮小制作的地球的模型

B.通過地球儀可以方便地知道地球的地貌

C.轉(zhuǎn)動地球儀,它繞一根軸在運動,證明地球里有一根旋轉(zhuǎn)軸

D.在地球儀上,地軸北段與地球表面的交點叫北極

2“地球圍著太陽跑”的方向是( 。

A.自南向北B.自北向南C.自東向西D.自西向東

3“地球自個兒也在轉(zhuǎn)”產(chǎn)生的現(xiàn)象是( 。

A.四季冷暖差異B.晝夜長短變化C.五帶的劃分D.晝夜更替

【答案】

1C

2D

3D

【解析】

本題主要考查地球儀、地球自轉(zhuǎn)的特點和自轉(zhuǎn)和公轉(zhuǎn)產(chǎn)生的產(chǎn)生的地理現(xiàn)象。

1人們?yōu)榱肆私獾厍虻娜,制作出了地球儀,地球儀是人們根據(jù)地球的形狀按一定的比例制作的地球的模型,地軸是地球儀圍繞轉(zhuǎn)動的一根軸,與地球表面相交于兩點,地軸北段與地球表面的交點叫北極,南段與地球表面的交點叫南極,地軸是一根假想軸,實際在地球上是不存在的。所以ABD敘述正確,C敘述錯誤。故選C

2“地球圍著太陽跑”指的是地球的公轉(zhuǎn),地球公轉(zhuǎn)的方向為自西向東。故選D

3“地球自個兒也在轉(zhuǎn)”指的是地球的自轉(zhuǎn),地球自轉(zhuǎn)所產(chǎn)生的地理現(xiàn)象有晝夜交替、日月星辰東升西落和時間差異。四季冷暖差異、晝夜長短變化、五帶的劃分,是由地球公轉(zhuǎn)產(chǎn)生的,所以ABC錯誤,D正確。故選D

地球繞地軸不停轉(zhuǎn)動,叫地球自轉(zhuǎn)。地球自轉(zhuǎn)的方向是自西向東,自轉(zhuǎn)的周期是一天。地球自轉(zhuǎn)產(chǎn)生的現(xiàn)象是晝夜交替、日月星辰東升西落和時間差異。地球公轉(zhuǎn)的周期是一年,方向是自西向東,公轉(zhuǎn)的中心是太陽,公轉(zhuǎn)產(chǎn)生的現(xiàn)象有季節(jié)的變化、晝夜長短的變化、五帶的產(chǎn)生、正午太陽高度的變化等。
