The Earth revolves around the sun at a speed of about 67,100 miles per hour. One whole orbit or revolution around the sun takes approximately 365.25 days, which comes out to a year. The extra 0.25 day is accounted in the extra day on leap years every 4 years. The Earth’s axis is ...
Until recently however, these two communities were mostly independent from one another and the potential resolving power of integrating their efforts in deep time has been largely underutilized.CRAMER, Bradley D
A. The rotation of the Earth B. The revolution of the Earth C. The movement of the moon D. The shape of the E. arth 相关知识点: 试题来源: 解析 B。地球的公转(The revolution of the Earth)导致季节的变化,地球的自转(The rotation of the Earth)导致昼夜交替,月亮的运动和地球的形状不是季...
could be alone in the universe. The first reason Earth was able to become this welcoming blue sphere is because it's at just the right distance from the Sun, in a narrow zone not too hot and not too cold, where the temperatures are compatible with liquid water and life....
A. The rotation of the Earth B. The revolution of the Earth around the Sun C. The moon's gravity D. The wind 相关知识点: 试题来源: 解析 B。解析:地球围绕太阳的公转引起季节变化。文章中讲解了地球的运动和季节的关系。选项 A 地球的自转产生昼夜交替。选项 C 月球的引力主要影响潮汐。选项 D ...
A. Earth's rotation B. Earth's revolution C. Moon's gravity D. Sun's gravity 相关知识点: 试题来源: 解析 B。本题考查季节的主要成因。选项 A,地球自转产生昼夜交替;选项 B,地球绕太阳公转导致太阳直射点的变化,从而产生季节变化;选项 C,月球引力主要影响潮汐;选项 D,太阳引力主要影响地球的轨道。反...
根据第二段中的“Proxima b,or ‘Earth Ⅱ’ as you could call it,is a little bigger than our Earth,and its revolution only takes 11 days”可知,比邻星b,或者你可以称它为“地球Ⅱ号”,比我们的地球大一点,它的公转周期仅有11天。相对于地球的公转周期(约365天)而言,比邻星b的公转周期要短得多。
What causes the seasons on Earth? A. The rotation of the Earth. B. The revolution of the Earth. C. The tilt of the Earth's axis. D. The distance from the sun. 相关知识点: 试题来源: 解析 C。地球四季是由地球自转轴的倾斜导致的,A 选项地球自转不会引起四季变化,B 选项地球公转是四...
A. The rotation of the Earth B. The revolution of the Earth C. The tilt of the Earth's axis D. The distance between the E. arth and the Sun 相关知识点: 试题来源: 解析 C。本题考查季节变化的原因。地球自转轴的倾斜导致了不同地区在不同时间接受太阳光照的角度和时间不同,从而引起季节变化...
C。本题考查季节变化的原因。地球轴的倾斜导致季节变化,A 选项 The rotation of the Earth 是地球的自转,B 选项 The revolution of the Earth 是地球的公转,C 选项 The tilt of the Earth's axis 是地球轴的倾斜,D 选项 The distance between the Earth and the sun 是地球和太阳之间的距离,所以选 C。...
