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
1-place experience day and night every 24 hours taaja protection this change from day to night cause temperature variation on the decision increase in temperature during day and decrease in temperature at night.
2-with rotation we also have time difference between places begin time as we travel west and loss time when we travel is this is because the sun rise in the east and so place to East Express the day earlier.
3-as the Earth rotates all particles in motion on the earth surface get deflected to the right in the Northern hemisphere and towards the left in the southern hemisphere the spinning movement kaje reflect in the direction of winds and ocean currents.
4-quotation gives us a sense of direction because we know that the sun rise in the east and sets in the west.
5-the rotation of the earth has also resulted in getting inpic will hear your saved their it bulging at the equator and plate in adipose this is because it is spin faster at the equator then at the pause and it gets more splayed out of the equator.
REVOLUTION
Revolution is the annual motion of the earth around the sun along a curve that we have 365 days in a year but once in every four years activated it adds up to 1 whole day.we take care of this study by inserting it in February every four year 10 February has 29 days every four years is called a leap year.
DISTRIBUTION OF HEATS
the earth has a spherical shape has the distribution of sun rays over the Earth differ from one place to place the equator receive the direct rays from the sun the surface area is limited and the sun rays travel to a shorter distance.
report the heat is intense the rays of the sun Beach Resort polar areas are more talented they travel through a longer distance and get skated has the heat is less intense.
when the northern hemisphere is detailed it experience summer and the southern hemisphere experience winter when the northern hemisphere is detail away from the sun it experience wind and the southern hemisphere experiences summer.
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.
SEASONS
The Four Seasons summer autumn winter and spring are caused by the insulation of the earth axis and its Revolution around the sun is reason for approximately three months with a change in season behaviour change in temperature and in the duration of day and night over the place located on the equator have hot water throughout the year.
gradually the earth reaches a position where the sun appears to be directly over the equator on September 23 and March 21 the day and night are equal in length on these days all over the world it is autumn in the Northern hemisphere and Spring in the southern hemisphere these are known as Equinox the Equinox on March 21 is known as spring Equinox and the Equinox on September 23 is known as autumn Equinox.
on December 22 Sun moves for the South to sign directly over the Tropic of Capricorn 23 1/2 degrees South the South Pole title to the day long and the nights are shorter and it is autumn in the southern hemisphere areas on the Antarctic circle get 24 hours of Daylight however due to the fact that the sun rays are very stated it is not very hot the southern hemisphere experience the longest day and the shortest night is known as Winter solstice.
the northern hemisphere experience reverse condition with short and long Nights the area above the Arctic circle image in complete darkness for about three months,
