explain rotation and revolution of the earth
Answers
Answer: ROTATION
The rotation of the Earth on its axis causes day and night. As the Earth rotates, only one-half of the Earth faces the sun at any given time. The half facing the sun is light (day) and the half facing away from the sun is dark (night). The animation below shows the Earth's rotation.When viewed above the North Pole, the Earth rotates counterclockwise, from west to east. This is also called a prograde rotation. Because of this direction of rotation, we see the sun rising every day in the east and setting in the west. If a planet spins in a clockwise direction, it is said to have a retrograde rotation. Venus is an example of a planet with a retrograde rotation.
The Earth rotates on its axis once every 23 hours and 56 minutes. So does that mean that all places on Earth experience 12 hours of light and 12 hours of dark each day? If you think about it, you know that that is not true. During certain times of the year we have more hours of daylight than at other times. Why is this? The answer is that the Earth's axis is not at a right angle with the sun. It is tilted slightly at an angle of 23.5°.
Revolution
In addition to rotating on its axis, the Earth also travels around the sun in a path called an orbit. The motion around the sun along its orbit is called a revolution. The amount of time it takes for a single trip around the sun is called a period of revolution. The period for the Earth to revolve around the sun is 365.24 days or one year. The .24 days is why every four years February has 29 days.
Earth's orbit is not a perfect circle. Instead Earth's orbit is slightly elliptical in shape. The animation below shows the Earth's revolution around the sun.
Answer:
The earth has two parts; Rotation; The movement of the earth on its axis is called Rotation. Revolution; The movement of the earth around the sun is called Revolution.
