Seasons Change

Here the seasons change from four positions of the earth as the sun orbits

The bus has been given. For the annual formation, the sun's rays fall somewhere vertically and somewhere diagonally, and the day-night decreases.

The sun's rays, which fall vertically, penetrate the lower air layers, making the earth's surface warmer. It’s not how the fallen rope comes playing with any more air, it is The vultures spread more than the vultures on the vines. This results in heat waves and seasons all over the earth's surface at different times in the city A. Shell-Cock gets South Sadakti. Change happens. Seasonal changes in the temperature of the earth from time to time. There are many ways to get the four ends of the earth while orbiting the sun. The explanation is found in Greek.

Winter in Riksh in Northern Hemisphere and Southern Galarne: 21st June is the last day of sunset. On this day the sun's rays are read vertically after Cancer. As a result, 7 days is the longest day and the shortest night here. From the first month and a half of June 21st to the following month, the total time is three months. Summer in the Northern Hemisphere at this time. At this time the sun's diagonal crescent was not small in the southern gallery and the night was large. That is why it was winter there.

Autumn in the northern hemisphere and spring in the southern hemisphere. That is why the temperature in the Arabian Peninsula is three months from east to one and a half months

Reasons for change of seasons: -

The sun's rays are read vertically and then diagonally somewhere in the earth's annual intermittent call. The resulting temperature difference

Happens and friends are surrounded. As a result of the annual gachchi, day and night decrease and increase, which means the amount of daylight

The longer the night, the more polluted the atmosphere. Thus at different times of the year the temperature varies across the surface and the seasons change. Day and night increase and decrease. When measuring the sun, the earth always rotates at 7.5 degrees. The result is different single. The change of seasons means that there is an angular variation behind the sunlight and the seasons change. Of the earth Mark the cries.

The length of the orbit is 36051726 km. This orbit is elliptical and the distance from the sun to the earth is not always equal. .The sun is closest to the earth on January 1-3

In contempt. This is called Porinclicm. Again the sun is from the earth on the 1st to 5th of July

Stays the farthest. Aphel: on The orbit of the sun and the earth, and the consequent change in the relative volume, prove that the orbit of the earth is elliptical. 4 As a result of sun heat

Varies and the seasons change. Our country is located in the northern hemisphere and has formed the Tropic of Cancer (high axis of 23) along the middle of the country. So with the change in density in the northern hemisphere

The seasons of Bangladesh change.

Section 3-4: The tides have their own motion in the different oceans of the world. As a result, the sea water swells for some time every day and the cheese grows high in the mall. Again it goes down for a while. Samurai water is like this.

After that prayers and cuts are done every 5 hours and 10 minutes. Regular swelling of sea water is called Hig Tika and low tide is called Ebb or Low Tide. The water in the middle of the coin is usually so high to three feet high and low; But due to the low severity of the sea bay near the coast, there is a lot of water there. This is the moon of the sea .
