What is meant by the inclination
of earth axis ? At what angle is the Earth axis inclined
Answers
Answer:
earth axis means axis of rotation while inclination is an angle. the angle is 23.5 degree . It is the angle that earth axis makes with her orbital planet.
Astronomers have found that the axis of our earth does not stand upright. It is tilted at an angle of 23 ½° from the perpendicular as shown in the figure, This is known as the inclination of the earth's axis. It is because of the tilted axis of the Earth that days and nights are of varying lengths in different parts of the Earth. Four main seasons are also caused due to the inclination of the Earth. If the axis of the Earth was vertical, then days and nights would be of equal lengths at all places, and the Earth would experience only one season throughout the year. The Earth's tilt was formed about 4.5 billion years ago, when an object of the size of Mars crashed into the newly formed planet Earth, it knocked our planet over and left it tilted at an angle. Earth's axis is the imaginary red line.
