all the planets in the solar system are in constant motion the earth moves around the sun and earth on its axis.
latest learn more about these movements and how it affect us.
ROTATION
Rotation of the earth.the axis of the Earth is imaginary line transfer the centre of the earth joining the North and South poles.it is not a vertical line but it title at an angle at 66 ¹/² degree with the horizontal place of the Earth orbit of 23 ¹/² degree with the line perpendicular this is card angle of inclination.
Our source of heat and light it is the sun stay stationary one place as Earth spins around because of its spiritual save only half of it gets light at time while the other half stay in darkness.
the part that gets light has day while the part in the darkness has night the circle that separates the lighted portion from the dark portion is called circle of illumination.
the earth moves from west to east and show the Eastern side has the sunrise earlier.
a common experiment to check is out of yourself to use a fixed source of light in a dark room and place a globe in front of its and gradually spin it from west to east as the globe is mean you will be able to see how the light get disturb.
if you marked out a city and study how the light on its move you would be able to check out the entire day from Dawn To the Lighthouse of the night and back to the dawn of the next day the diffuse light which illuminates the earth just before Sunrise is called on and the same is called to light after sunset.
the tilt of the earth Axis as roadside does during summer it is never completely dark at the poles and never entirely lit up in winter.
however at the equator with the light first belt clear there are 12 hours of Sunlight order light throughout the year.
HOW ROTATION AFFECTS US
REVOLUTION
DISTRIBUTION OF HEATS
VARIATION IN THE LENGHT OF THE DAY AND NIGHT
we have an equal days and nights because of the Earth revolution and the insulation of the earth Axis at 66 One by Two degree if we study the diagram carefully be noticed a difference in the number of the Lighthouse at different latitude at different times of the Year places on the equator have equal division of the days and nights recharge 12 hours of daylight and 12 house of Darkness as we move towards the polls that days becomes longer during the summer and it becomes longer during the winter.
