Answer:

A rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object can always be rotated about an infinite number of imaginary lines called rotation axes . If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin. A rotation around an external point, e.g. the planet Earth around the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity. The axis is called a pole.

In political science, a revolution is a fundamental and relatively sudden change in political power and political organization which occurs when the population revolts against the government, typically due to perceived oppression or political incompetence.

Revolution is the movement of the Earth around the Sun. The Earth takes 24 hours to complete a rotation with respect to the sun. ... The path of the Earth moving around the Sun is called an orbit. The Earth's orbit is elliptical.

A leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day (or, in the case of a lunisolar calendar, a month) added to keep the calendar year synchronized with the astronomical year or seasonal year. Because astronomical events and seasons do not repeat in a whole number of days, calendars that have the same number of days in each year drift over time with respect to the event that the year is supposed to track. By inserting (called intercalating in technical terminology) an additional day or month into the year, the drift can be corrected. A year that is not a leap year is a common year.

Answer:

rotation- the movement of earth on its axis is called rotation. this causes day and night .

revolution- movement of earth around the sun is called revolution. this causes change in seasons .

leap year - every year 6 hrs are saved and 4 th year it makes a new day so there is 366 days in a leap year .
