The Reason For The Change - 1190 Words

The reason for the change in seasons is the tilt of the earth’s axis. It is not because of the earth’s distance from the sun like many people think. In the northern hemisphere, during winter, we are closer to the sun which is opposite of what most people assume. While the northern hemisphere is experiencing summer, the southern hemisphere is experiencing winter and vice versa. The sun is actually closer to the earth during the winter and farther away during the summer. Rotation is when something turns with a circular movement around a central point. Revolution is the path of the earth around the sun or one complete cycle of orbit around the sun. When the earth is revolving, it is going through the days and the year. One full cycle of a†¦show more content†¦During the vernal and autumnal equinoxes, is when there is equal amounts of light and darkness. The sun rises and sets at due east and due west. On the first day of fall in Cleveland, the sun will rise at 7:15am and it will set at 7:23pm. On the first day of winter in Cleveland, the sun will rise at 7:50am and will set at 5:00pm. I learned a lot from this exercise, I learned that the change of the seasons is not exactly what I thought it was. I learned the difference between the earth’s revolution and rotation which was very interesting. I also learned when the shortest and longest days of the year happen. It was a very informative exercise to do. The hydrosphere is all of the waters on the earth’s surface, it includes lakes, seas and more. The ocean itself, covers over 70% of the surface of earth. Around 2% is accounted for in the shape of glaciers and ice caps. There is a lot of water on earth. It makes me wonder why there are places going through dry spells if there is that much water that is on our planet. The way water moves in the water cycle is â€Å"The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air; a relatively smaller amount of moisture is added as ice and snow sublimate directly from the solid state into vapor. Rising air currents take the vapor up into the atmosphere, along with water from evapotranspiration, which is water transpired from plants and evaporated from the soil. The vapor rises
