a.Occurrence of season one after the other.
b.Changes in atmosphere.
c.Occurrence of rain in a specific period.
d.All of the above.

Answer 1

Hint: Season is a division of the year based on modifications in weather, ecology, and the number of sunlight hours in a given region. On Earth, seasons are the outcome of Earth's orbit around the Sun and Earth's axial slant comparative to the ecliptic plane. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant.

Complete Step by Step Answer:
The 2 factors which explain the cycle of seasons on the Earth is the ;
Tilt of Earth's axis, and
Orbital motion around the Sun.
The Earth's tilted axis affects the seasons. As Earth revolves the sun, its slanted axis always points in the identical direction. So, throughout the year, different fractions of the Earth receive the Sun's most immediate rays. When the North Pole is tilted towards the Sun during June it's summer in the Northern Hemisphere because the sun's rays strike that part of the Earth more immediately than at any other time of the year. It is winter in December in the Northern Hemisphere, because that is when the South Pole is tilted towards the Sun. Midway between these two times, in spring and autumn, the bend axis of the earth points 90 degrees away from the sun. This implies that on this date, day and night have about the same length, that is, 12 hours each, more or less.
For the Northern Hemisphere, the axis points most toward the Sun on June 21 and away from the sun around December 21. This corresponds to the Winter and Summer Solstice. Reverse happens for the Southern Hemisphere.
For both the hemispheres, the earth is 90 degrees away from the sun around March 21 and then likewise around September 21. This approximates to the Fall and Spring Equinox.

Hence, all the options justify the answer and option 'd' is correct.

Note: The seasons can give rise to a wide variation to the year for those areas that encounter them in full. Each season brings with it its own aptitude dangers, but also its unique trademark of beauty.
