‘Write an essay on theseason-change in Bangladesh during the four states of the earth while rotating around the sun.’

 

Seasons change – The seasons change due to the rotation of the earth in its own orbit and the axis tilted towards the sun. The seasons on the earth change because different parts of the earth are towards the sun or opposite to the sun at different times for the rotation of the earth around the center of the sun.

Reasons for changing seasons-

1 / Increase or decrease in heat due to variation of day and night in different parts of the world-

The earth revolves around its own axis as it orbits the sun. As a result, the earth’s surface heats up in the direction of the sun’s hemisphere and the temperature decreases in the opposite direction. The heat that the earth’s surface receives on the big day, the heat on the small night is not able to radiate completely, the weather warms up and the summer weather prevails. Being larger and smaller in the opposite hemisphere, it radiates all the heat at night and feels cold and winter.

2 / Round shape of the earth –

The sun’s rays sometimes fall vertically and sometimes diagonally to make the earth round. As a result, the seasons change due to temperature differences.

3 / Earth’s elliptical orbit –

For the Earth’s elliptical orbit, the Earth’s distance from the Sun is not the same throughout the year, resulting in a difference in temperature and a change of seasons.

4 / Angular position of the Earth’s orbit-

Leaning at an angle of 8.5 degrees above the Earth’s orbit is always in the same direction. It moves closer to the North and South Poles once a year, and this position of the Earth results in an increase in the number of days and nights. As a result, the angular fall of the sun’s rays varies in different places and the seasons change.

5 / Eccentric motion of the earth-

Day and night occur as a result of the motion of the ahni on earth. The earth is rotating from west to east on its own axis or polar line. Thus the speed of rotation of the earth takes 24 hours or 1 day. Exactly its time is 23 hours 56 minutes 4 seconds. The motion of the earth is eclipsed. Who says that if there was no ecliptic ecliptic during a full rotation of the earth, there would always be summer somewhere in the earth and winter all the time somewhere.

The process of changing seasons-

The explanation of the change of seasons can be found from the four states of the earth during the period of rotation of the sun.
Such as –

1 / Summer in Northern Hemisphere and Winter in Southern Hemisphere –

June 21 is the last day of the setting of the sun. On this day the sun’s rays fall perpendicular to the Tropic of Cancer. As a result, that day is the longest day and the shortest night here. The heat in the northern hemisphere is higher for a total of three months from the 21st of June to the first month and a half. It is summer in the northern hemisphere. During this time the day and night in the southern hemisphere get bigger because of the diagonal rays of the sun. That is why it was winter there.

2 / Autumn in Northern Hemisphere and Spring in Southern Hemisphere-

On 23rd September the sun’s rays fall perpendicular to the equator and day and night are equal everywhere. That is why the temperature is moderate for a total of three months from one and a half months to one and a half months after this date. Autumn in the northern hemisphere and spring in the southern hemisphere.

3 / Winter in Northern Hemisphere and Summer in Southern Hemisphere-

December 22 is the last day of the solar eclipse, that is, the sun shines vertically on Capricorn. As a result, day and night are short. A month and a half before and after this date is summer in the southern hemisphere and winter in the northern hemisphere.

4 / Spring in Northern Hemisphere and Autumn in Southern Hemisphere-

On the 21st the north and south poles are equally far from the sun. On this day the sun shines vertically on the equator and day and night are equal everywhere. These three months are spring in the northern hemisphere and autumn in the southern hemisphere.

During the orbit of the sun, four conditions of this earth exist in Bangladesh-

Early season –
Summer in the Northern Hemisphere and Winter in the Southern Hemisphere, Bangladesh is located in the Northern Hemisphere. Because at this time the sun shines vertically on the Tropic of Cancer line. The month of June is hotter and the monsoon winds of June-July bring rains.

2 / Second condition- Spring in Northern Hemisphere and Southern Hemisphere, on 23rd September the sun shines vertically on the equator. Day and night are equal everywhere in the world. The amount of cold heat in the weather is the same as the heat radiation is the same in three flights. During this time, the autumn season changes from a month and a half ago, i.e. from August to September, from the rainy season. Later September-October autumn prevails.

Condition 3 – Winter in Northern Hemisphere and Summer in Southern Hemisphere,
After 23rd September, the Northern Hemisphere moves away from the Sun. On 22nd December, the Sun shines vertically on Capricorn. At that time in the northern hemisphere, that is, in our country, as the days get shorter and the nights get bigger, it becomes winter. Which lasts for about the next three months.

Fourth condition – Winter in the Northern Hemisphere and Southern Hemisphere, the sun’s rays perpendicular to the equator make day and night equal throughout the earth. The surface is heated by the heat of the day sun, but at night it becomes evenly distorted and becomes cold. Therefore, at this time in the northern hemisphere, that is, in Bangladesh, there is an occasional cold and hot situation. It is called spring time.
