Test: Effect of the tilted axis on day & night - Delhi Police Constable MCQ

The Earth experiences different seasons due to its revolution around the Sun. As the Earth moves in its orbit, the tilt of its axis causes different parts of the planet to receive varying amounts of sunlight, leading to the change in seasons.

During the vernal equinox, which occurs around March 20-21, the day and night are approximately equal in duration worldwide. This happens because the tilt of the Earth's axis is such that the Sun is directly above the equator during this time.

During the summer solstice, which occurs around June 21, the North Pole is tilted towards the Sun, resulting in 24 hours of continuous daylight at this location.

The Earth's axis is tilted at an angle of approximately 23.5 degrees with respect to its orbital plane, which is the primary reason for the changing seasons.

The length of daylight a region receives during different seasons is mainly determined by its latitude and the tilt of Earth's axis. Regions closer to the poles experience more variation in daylight throughout the year compared to equatorial regions.

The apparent movement of the Sun on the horizon throughout the year is due to the variation in the Earth's axial tilt. As the Earth orbits the Sun, the tilt causes different parts of the planet to receive sunlight at different angles, leading to the perceived change in the Sun's position.

During the winter solstice in the Southern Hemisphere (around June 21), the Antarctic Circle experiences 24 hours of continuous darkness, as the South Pole is tilted away from the Sun.

The tilt of Earth's axis is the primary reason for the change in day length as we move from one season to another. As the tilt causes different parts of the Earth to receive varying amounts of sunlight, day length varies throughout the year.

Solstice occurs twice a year when the Sun reaches its highest (summer solstice) and lowest (winter solstice) positions in the sky relative to the Earth. These events mark the beginning of summer and winter, respectively.

The Equator experiences relatively constant day and night duration throughout the year because it is perpendicular to the Sun's rays during both equinoxes, resulting in approximately 12 hours of daylight and 12 hours of darkness.

The longest day of the year in the Northern Hemisphere is known as the summer solstice, which occurs around June 21. On this day, the Northern Hemisphere is tilted towards the Sun, resulting in the longest duration of daylight.

The tilt of the Earth's axis is responsible for the changing seasons, as different parts of the Earth receive varying amounts of sunlight throughout the year.

The Earth's axial tilt causes the number of daylight hours to increase during the summer in the Northern Hemisphere, as the region is tilted towards the Sun.

During the winter solstice, which occurs around December 21, the Antarctic Circle experiences continuous darkness because the South Pole is tilted away from the Sun.

During the equinoxes (vernal and autumnal), which occur around March 20-21 and September 22-23, the day and night are of approximately equal duration all over the world.

During the summer solstice, the North Pole receives the longest duration of daylight due to its tilt towards the Sun.

 If the Earth's axis were not tilted, there would be no change in seasons because all regions would receive the same amount of sunlight throughout the year.

During the autumnal equinox, which occurs around September 22-23, the Sun is directly above the equator, leading to approximately equal day and night duration worldwide.

The winter solstice occurs when the Sun is directly overhead at the Tropic of Capricorn, around December 21. This marks the beginning of winter in the Northern Hemisphere.

The tilt of the Earth's axis causes the angle of sunlight to vary with the seasons. During summer, the angle is more direct, leading to warmer temperatures, while during winter, the angle is more oblique, resulting in cooler temperatures.
