The Effects of the Seasons Change in Space

The first effect that the orbit of the earth has is seasons. Because the earth is tilted on a 23.4 degree angle (obliquity) different areas of the earth get more energy and heat from the sun at different times of the year. When the earth orbits the sun, it's always on the 23.4 degree tilt, which means that at different times of the year, different parts of the world receive more or less energy from the sun because different areas of the world tilt toward or away from the sun. Some people think that earth has seasons because at some points of the year, the earth is closer to the sun. This is because earth has an off center elliptical orbit. Seasons are always opposite. This is because of the earth's rotation and tilt, meaning that one part of the earth is facing toward the sun and the other half is facing away. For example, the northern hemisphere experiences summer in June, July and august while the southern hemisphere experiences summer in December, January, February and march. When the south pole is tilted toward the sun, the southern hemisphere will be experiencing summer, and the northern hemisphere will be experiencing winter. The orbit of the earth around the sun is linked to controlling the seasons of the world because of the tilt that the earth is on and how the earth orbits around the sun. This is because when earth is at a specific place during its orbit, the southern hemisphere will be tilted towards the sun, and the northern hemisphere will be tilted away, meaning that around 6 months later, the earth will be in a different position during its orbit, and the seasons will be reversed in both northern and southern hemispheres.

Overall, the orbit of the earth astronomical cycle is linked to seasons on earth and temp difference between seasons because the combination of the 23.4 degree tilt that the earth is on with the orbit of the earth around the sun, different parts of the world receive more or less heat energy from the sun because different areas of the world tilt toward or away from the sun. The second effect of this astronomical cycle is the temperature difference between seasons. The temperature difference between the 4 seasons is due to how the sun hits the earth and the angle that the sun hits the earth. When it's warmer in summer, the sunlight rays hit the area of the earth at a high angle. This means that the rays hit a smaller part of the earth. In winter when it is colder, the rays of the sun hit the earth at a smaller angle meaning that the sun appears to be lower in the sky. Because the sun hits the earth at a smaller angle, the rays hit a larger part of the earth and spread over a larger surface area. The temperature difference of the seasons is linked to the orbit of the earth because of the combination of the orbit of the earth with the tilt of the earth. This means that different areas of the world receive more or less energy from the sun than other parts of the world. This means that when the south pole is closest to the sun, it is summer in the southern hemisphere, and vice versa.

A solstice is the two points in the year where the sun reaches its highest and lowest points in the sky. These two solstices are the summer solstice and the winter solstice, which are determined by the shortest and longest days of the year. Equinoxes are the point when the sun is directly above the equator and the two equinoxes determine night and day of exactly equal length. The two equinoxes also mark the start of spring and autumn. The summer solstice in the southern hemisphere will occur on 22 december 2019, this marks out the longest day of the year and the first day of summer. The difference between solstices and equinoxes are that solstices mark the shortest and longest days of the year (first day of summer and winter), while equinoxes mark the two equal days of the year (Beginning of spring and autumn)Much like the earth orbits around the sun, the moon orbits the earth. The moon is about 384,000 kilometers from the earth and the moon takes 27.322 days for a full orbit to be complete. The moon orbits on its axis just like the earth, but is only tilted 1.5 degrees on its axis and is not spinning on its axis. The orbit of the moon is not a perfect circular orbit, with the average eccentricity being 0.549. Only one half of the moon faces the earth, and this is named the near side of the moon. The other side of the moon is named the far side. The orbit of the moon around the earth has many effects such as tides and how they work, neap and spring tides, phases of the moon and eclipses.
