What causes the four seasons to change on Earth?

What causes the change of the four seasons on the surface of the earth, the four seasons occur simultaneously on the surface of the earth, what is the main factor that causes the change of the four seasons, where we find that the year has four different seasons where there is a summer season characterized by its temperature and there is a cold winter season in addition to the two seasons of spring And autumn, and when the seasons change, the colors of the leaves of the trees begin to change, or precipitation according to the current season and explain the reasons for the four seasons change on the surface of the earth.

What causes the four seasons to change on Earth?

What causes the four seasons to change on the surface of the earth is the tilt of the earth’s axis, because at different times of the year, the sun’s rays begin to hit different parts of the globe directly, such as the angle of the earth’s axis, the northern hemisphere is tilted towards the sun during the summer as well, so if The Earth was not tilted, the regions around the equator would receive most of the sun’s rays, plus the northern and southern hemispheres would remain locked in a slight dip between hot and cold, so the temperature would be roughly the same all year round.

What causes the tilt of the Earth’s axis?

Scientists believe that the reason for the Earth’s inclination is its collision with primitive planets, as this caused the Earth to tilt slightly instead of rotating on its straight axis up and down, as happens when the Earth rotates around the sun. Its tilted axis always points in the same direction, and so different parts of the Earth receive light. Direct sun throughout the year, plus the fact that the north pole is sometimes tilted towards the sun, which is around June, plus the fact that the south pole is sometimes tilted towards the sun, which is around December.

What is the Earth’s orbit?

The Earth’s orbit is its rotation around the Sun, as the Earth rotates counterclockwise on its axis at an angle of 23.4 degrees, and this rotation results in existence, because at that time only half of the Earth’s hemisphere was directed towards the Sun, in addition, it takes the Earth 365 days to complete its orbit In addition, as a result of the tilt of the Earth’s axis, it receives different amounts of sunlight, which gives rise to the four seasons.

The most important characteristics of the four seasons

The planet Earth is a ball divided into a northern and southern part, so if the sun’s rays fall on the northern side to a high degree, then this is the summer season, then the winter season dominates on the other side of the globe. It is worth noting that each of the four seasons has some features mentioned below.

Summer season

The summer season begins when the day becomes the longest period of the day, while the night is the shortest period of the day, and mosquitoes, as well as the growth of most animals born during the spring.

The autumn

Autumn is known for its cooler temperatures than the previous summer, in addition to the fact that the leaves on trees turn yellow and fall off the trunk, it is also the time for most animals to prepare to hide for the coming winter, and some of them go to places where the temperatures rise, and the temperatures continue to drop Gradually, with the possibility of rain eventually.

winter season

It is one of the most difficult seasons of the year, as temperatures reach their lowest levels during this, in addition to the absence of leaves or fruits on the trees, so they are dry and dry, in addition to heavy rains that can turn into snow as well, such as cold winds, the appearance of the sun is possible and the temperature moderate.

spring season

The summer season is lively after the harsh winter as the temperatures rise gradually, in addition to the fact that the trees are blooming, covered with green leaves, in addition to the growth of grasses and herbs, and a range of tree species can mature, in addition to the fact that most animal births occur in the spring.

Important facts about planet Earth

Earth is the third planet in the solar system and it is also the only planet whose name is not taken from the name of a Greek or Roman god, in addition to the fact that the Earth was formed about 4.54 billion years ago, moreover, there is no other planet that supports life and it is worth noting that there is Collection of facts related to the Earth as follows

  • The radius of the Earth is 6,370 kilometers, or 3,980 miles, while the radius of the Sun is about 100 times larger.
  • The earth revolves around the sun once a year, and this orbit is slightly elliptical.
  • The average distance from the Earth to the Sun is about 149 million kilometers, or about 93 million miles.
  • Planet Earth is closest to the sun, also during the month of January, while it is farthest from it in July.
