Question

100 lines about 'the revolution of the Earth".






Its quite urgent.... so guys plzz hurry :(

Answer 1

the movement of Earth around the sun is called revolution.
Earth takes 365.6days to complete one revolution around the sun which is the time period of one year.
The revolution of the earth is the cause for the seasons on the earth.
Earth revolves around the sun with a speed of 108000km/hr.

Answer 2

Earth revolves around the sun in a counter-clockwise manner with one complete revolution taking 365 ¼ days. This extra quarter day is responsible for our leap year every four years. But, the revolution of Earth is responsible for things much more noticeable than leap years. It's also responsible for our changing seasons.

Notice how the earth has its top tilted away from the sun? This means the Northern hemisphere (the top half) receives less direct solar radiation than the Southern hemisphere (the bottom half). That variance causes the Northern hemisphere to experience winter, while the Southern hemisphere experiences summer.

If Earth didn't revolve, this situation would never change and the Northern hemisphere would experience constant winter. Fortunately, Earth is not static and does revolve. When the Northern and Southern hemispheres are experiencing equal amounts of direct solar radiation, this translates to spring and fall in the respective hemispheres, depending on whether we are moving towards summer or winter.

hope it will help you ✌️
