(6) What is a revolution?
Answer: Earth orbits the sun in an elliptical orbit called revolution.
(7) How long will it take for the earth to undergo a revolution?
Answer: It takes 365 days for one revolution.
(8) What is a leap year?
Answer: The year in which the number of multiplications in February does not differ by 29 days, not 28 days is called a leap year.
(9) What is Earth parallelism?
Answer: Earth is at an angle of 66 1/2 degrees from the orbital plane and measured from the vertical plane, which is 23 1/2 degrees.
(10) What are the reasons for the seasonal differences? And how does the distance between the sun and the earth differ throughout the year?
Answers:
(i) The main reason for seasonal variations is the variation in the amount of sunlight. A different part of the earth gets direct sunlight for whole year. So when the North Pole tilts toward the sun, it is summer in the Northern Hemisphere, and when the South Pole is tilted toward the sun, it is winter in the Northern Hemisphere.
(ii) The distance between the Sun and Earth varies continuously during one revolution, the day when the Earth is closest to the Sun is January 3 is called the Perihelion, and July 4, the Earth is furthest from the Sun is called Aphelion In this way the distance between the sun and the earth varies throughout the year.
(11) What is the apparent movement of the sun relative to the earth?
Answer: The position of the sun varies between the Tropic of Cancer (23 1/2 ° N) and the Tropic of Capricorn (23 1/2 ° South Latitude); this is called the movement of sunlight.
(12) How long does it take for the earth to rotate on its own axis?
Answer: It takes Earth 24 hours to rotate on its own axis.
(13) Why do seasonal changes usually do not occur in the tropics?
Answer: The tropics are close to the equator, an imaginary line circling the center of the earth. This area receives strong sunlight all year round. Therefore, the tropics do not have the four seasons available in other parts of the world.
(14) Why do seasonal cycles repeat throughout the year?
Answer: Due to the movement of sunlight between the Tropic of Cancer (23 1/2 ° N) and the Tropic of Capricorn (23 1/2 °), because the different seasons of spring, summer, fall and winter recur in this seasonal cycle throughout the year.
(15) What variations occur as a result of the movement of sunlight on Earth?
Answer: Variations occur due to variations in sunlight falling on the earth. The sun’s rays fall vertically above the hemisphere, in other parts of the world the temperature will be higher than where the sun’s rays fall vertically. The temperature will be low in places where the sun is shining.

Answer: On June 21, the southern hemisphere has a few hours of daylight and most of the year.
(19) Give a reason why the days and nights on March 21 and September 23 are the same in both hemispheres?
Answer: On March 21, the same amount of sunlight reaches the northern and southern hemispheres, and on September 23, the sun is just above the equator and the north and south poles complement the sun. Therefore, the days and nights during those two days are the same all over the world.
(20) What season sees the Northern Hemisphere on September 23rd?

4 minutes

4 × 15 = 60 minutes.
