Answers
Answer: rotation, revolution
Answer:
MOTIONS OF THE EARTH
Earth basically has two types of motions. They are rotation and revolution. These two motions are responsible for different kinds of phenomena. Let us look into them in further detail.
Rotation of the Earth
Rotation is the movement of the earth on its axis. Days and Nights take place because of rotation. So, the days and nights that you see are actually because of this rotation of the earth around its own axis. The axis of the earth, which is an imaginary line, has axis tilted at an angle of 66.5 ° with its orbital plane. The circle that divides the day from night on the globe is called the circle of illumination.
Revolution of the Earth
Revolution is the second type of motion of the earth. It is the movement of the earth around the Sun in a fixed path or orbit. Revolution causes the change of seasons. It takes 365days and 6hours (one year) to revolve around the sun. It is important to note that we consider a year as consisting of 365days only and ignore six hours for the sake of convenience.
Leap Year
Six hours saved every year are likely to make one day (24hours) over a span of four years. We add this surplus day to the month of February. Every fourth year, February is 29 days instead of 28 days. This year with 366 days is called a leap year.
