# What are the two factors responsible for the formation of season 6?

Seasons are caused by the tilt of the Earth's rotating axis away or toward the sun as it moves around the sun year after year. The Earth's angle with respect to the "ecliptic plane" is 23.5 degrees (the imaginary surface formed by its almost-circular path around the sun). When this angle is 0 degrees, the Earth is directly over the center of the Sun; when it is 90 degrees, it is over a point on the Earth's surface called the "permanent polar ice cap." At other angles between these limits, certain regions receive more sunlight than others, causing changes in the environment that lead to vegetation growth or desertification.

When the Earth orbits the sun, it does so in an elliptical shape. The major axis of this orbit is called its "axis of rotation." The distance between the centers of the Earth and sun varies depending on where the Earth is in its orbit. When the Earth is at its perihelion, closest approach to the sun, it is about 91 million miles from the sun. At its aphelion, farthest from the sun, it is about 94 million miles away.

During a solar eclipse, the moon blocks out part of the sun while passing over the Earth. Because the moon's orbit is inclined 5 degrees to the Earth's equator, only parts of the moon's surface are exposed to direct sunlight. The rest faces away from the Earth.

Seasons are caused by the tilted axis of the Earth. The angle that this axis makes with the plane of the Earth's orbit around the Sun is called the Earth's obliquity. This angle changes over time due to rotations and translations on the surface of the Earth, and since these processes occur at different speeds they cause seasons of different lengths and profiles.

The length of a season can be calculated from simple geometry: the distance between the North and South Poles is 2+ miles (3.2+ km). The radius of the Earth is 3,924 miles (6,378 km), so adding them together gives a distance of 7,828 miles (12,677 km). This is almost exactly half the mean distance between the Earth and the Sun, so if we divide this by two we get the average separation between the Sun and the Earth, which is how far back a ray of sunlight will have to travel before it hits the same spot again. This is called the solar day and it's about 86,400 seconds (or 1 AU); at the equator this becomes 90% of the way around the planet, or about 47 minutes per degree of latitude.

## What are the two things responsible for the change of season?

Seasonal changes are generated by the rotating tilt of the earth on its axis as it rotates around the sun. The earth has a tilt of 23.50 on its elliptical plane, and when the tilt shifts towards or away from the sun as the world revolves around the sun, the seasons change. The amount of shift determines how much difference we see between winter and summer.

The angle that the earth makes with the sun varies because of its rotation, but it is generally thought that if all other factors were equal, the distance would vary in accordance with a simple formula: half the distance to the moon plus one quarter the distance to the moon multiplied by 12 (the number of months in a year). But this isn't exactly true, because the earth also orbits around the sun which gives it an additional force that affects how far it travels per year. This means that the actual distance between the earth and the sun varies over time.

But even after taking this effect into account, we can still estimate that the average distance between the earth and the sun is about 150 million km (93 million miles).

During an eclipse of the moon, only part of it is blocked out by the shadow of Earth, so some sunlight reaches it. However, most scientists agree that only 3% of that light gets through to space because most of it is obscured by our atmosphere.

## What are the factors responsible for the change in season, short answer?

The sun and the Earth The tilt of the Earth toward the sun causes the seasonal cycle. The planet revolves on an unseen axis. The northern or southern axis is closer to the sun at various periods of the year. When the north-south axis is tilted towards the sun, we experience summer; when it is tilted away from the sun, we experience winter.

The angle between the equator and the plane of the earth's orbit around the sun is called the "eccentricity" of the earth's orbit. For example, if the earth were in a perfect circle around the sun, the seasons would not change. But because we are not in a circle, but an ellipse, the angle between the equator and the plane of the orbit changes over time. This changing angle causes us to experience different temperatures at each location on earth.

The distance of the earth from the sun determines how much heat we receive. As the earth gets closer to the sun, it receives more heat energy. As it moves farther away, it receives less heat energy. This is why you can find places on earth that experience cold winters and hot summers. If the earth was always the same temperature, then animals could not move from the warm tropics to the cold tundra, nor could humans survive without technology.
