【解析】
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。
【1】地球繞地軸不停轉(zhuǎn)動,叫地球自轉(zhuǎn)。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。
故選:C。
【2】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)象是晝夜交替和時間差異等。北京的小紅在晚上給美國紐約的姨媽打電話,小紅的姨媽向小紅道早上好,體現(xiàn)了地球自轉(zhuǎn)形成的時間差異。
故選:C。
【3】地球五帶中季節(jié)變化最明顯的是北溫帶和南溫帶,故B正確。
故選:B。
【4】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,地球公轉(zhuǎn)時,地軸的空間指向不變。
故選:D。
第1題考查的是地球自轉(zhuǎn)的概況,屬基礎(chǔ)題。
第2題考查的是地球自轉(zhuǎn)產(chǎn)生的現(xiàn)象——時間差異,理解解答即可。
