What are the three types of motion of the earth

 

  

Motion of the Earth: the Earth is in constant motion,revolution of Earth around the sun and it's rotation around its own axis .these motion result a number of consequences like occurrence of days and nights, changes in seasons and climates in different areas and regions . Movement of the Earth around its axis and around the sun can be easily understood by mounting a globe and rotating it around its axis, and movement of the Earth around the sun can be illustrated easily.   1) Rotation: if you see at the figure 11,it looks somewhat tilted.The earth completes it's rotation in the time of one day .Rotation is also called spinning. The earth spins around its axis from west to East. Rotation of the earth cause days and nights. The rate of rotations is approximately 1,038 miles per hour, decreasing to zero at the poles. Tilting of Earth causes occurrence of different seasons.  

2) Revolution: the motion of the Earth around the sun is called revolution .earth completes is revolution around the sun in the time of one year. The path on which earth revolves is called Earth ,s orbit. It is nearly an elliptical path. The mean distance of the earth from the sun is about 93million miles and the distance varies by 3 million miles, forming a slightly elliptical path. The revolution of the Earth around the sun travels a distances of 595 million miles in 365 days, 6 hour ,9 minutes and 9.5 seconds.This means that average speed of the earth is 18 miles a second.     3) Influence of the sun and the Moon on Earth: the sun influence the earth in many ways. The sunlight,warmth,and the chronology are the influences of the sun, whereas moon has its own influences on the earth. They are gravity and it's motion. The moon orbits the earth due to the gravity of the earth .the moon also have gravitational power but moon,s gravity is 1.6 where as the gravity of the earth is 10m/S2. By the way gravity pulls the earth and moon toward each other tides are caused (high tide and low tide) due to the gravity of the moon. The sum also has some influence here. The sun brings light and is also responsible for the warming up of the earth.
