Answer 1

Answer:

1/9. An equinox is an event in which a planet's subsolar point passes through its Equator. The equinoxes are the only time when both the Northern and Southern Hemispheres experience roughly equal amounts of daytime and nighttime

Explanation:

In geometry, rotations make things turn in a cycle around a definite center point. Notice that the distance of each rotated point from the center remains the same. Only the relative position changes. In the figure below, one copy of the octagon is rotated 22 ° 22\degree 22° around the point.

A leap year is a year in which an extra day is added to the Gregorian calendar, which is used by most of the world. A common year (an ordinary year) has 365 days, but a leap year has 366 days. The extra day, February 29, is added to the month of February.

Answer 2

1.One of the two times in the year (around 20 March and 22 September) when the sun is above the imagined line round the centre of the earth (equator) and day and night are of equal length is called Equinox.

2.Movement in circles around a central point is called Rotation.

3.One year in every four, in which February has 29 days instead of 28 is called leap year.
