解析 地球之所以有不同的季节,是因为地球自转轴倾斜并且地球绕太阳公转。地轴倾斜导致地球在公转轨道的不同位置,太阳光照射的角度和时间不同,进而导致地球上不同地区接收到的太阳能量差异,最终形成了四季变化。 1. **地球绕太阳公转:** 地球并非静止不动,而是沿着一个轨道绕着太阳运行。 2. **地轴倾斜:** 地球...
B Earth rotates(旋转) on its axis(轴) as it moves around the Sun, completing one full rota-tion every 24 hours. Earth's axis is an imaginary line that passes through the North Pole and South Pole. As a result of Earth's rotation, regions alter-nately(交替地) face the Sun and fac...
Orbiting and Spinning 公转与自转 It takes Earth a whole year to make a complete orbit around the Sun.As the Earth moves around the Sun,it is also spinning on its axis.地球绕太阳运行一圈的时间是一年。地球在太阳周围运行的时候，也在自身轨道上自转。One full turn or spin, on Earth's axis...
The Earth's orbit around the Sun Start What does the Earth's orbit around the Sun look like? Seasons Start What induces the seasons? How high is the sun over the year in different latitudes? And how would the situation change when the Earth's axis had a different slope?
Our planet set a record for completing one rotation faster than scientists had ever previously recorded, according to TimeAndDate.com. Earth rotated once around its axis on Wednesday, June 29, in 1.59millisecondsless than 24 hours. 据TimeAndDate.com称,我们的星球创造了完成一次自转比科学家以往记...
In one year the earth travels right around the sun. The diagram(图表) shows the earth at four different times of the year. Notice how the axis(地轴) remains tilted(倾斜的) at the same angle. First one hemisphere, then the other, is titled towards the sun.In June, when the northern ...
When your town has winter, the earth's axis(轴) is pointing away from the sun. Your town doesn't get as much light or heat from the sun. The days are shorter and colder.Winter and summer happen because the earth is tilted(倾斜) as it revolves around the sun.The northern end of ...
So, Jupiter started migrating to the Sun, but when Saturn appeared there was a complicated gravitational effect which reversed the migration, and the planets moved further from the Sun. Thanks to Saturn, the giant planet Jupiter changed trajectory.所以，木星开始向太阳迁移，但当土星出现时，一个复杂...
