Solar rays strike the Earth at varying angles depending on the time of day, season, and geographic location. At solar noon, when the sun is highest in the sky, the rays can be nearly perpendicular (90 degrees) to the surface at the equator. However, as you move towards the poles or during different seasons, the angle decreases, leading to more oblique rays. This variation affects the intensity of sunlight and influences climate and temperature patterns.
As the angle at which the sun's rays strike the Earth's surface increases, the temperature tends to decrease. As the angle decreases, temperature tends to increase. At the same time, as the sun's angle decreases, shadows appear longer because the light is being cast at a greater angle.
The sun rises each year at the South Pole about September 21 and sets each year about March 21. This means six months with no sunsets. The maximum height of the sun above the horizon is only 23.5 degrees, so you could consider it less sun, except that you don't offer a comparison.

No, solar rays do not strike the equator at a 180-degree angle. The angle at which the sunlight strikes the equator varies throughout the year due to the tilt of the Earth's axis. This variation is what causes the seasons.
23.37 degrees Meaning that the Poles are tilted at 23.37 degrees to the angle at which the Sun's rays strike the Earth.
The angle at which the sun's rays strike the Earth's surface varies depending on the Earth's rotation and its position in relation to the sun. This angle changes throughout the day as the Earth rotates on its axis and as the Earth orbits around the sun, causing different parts of the Earth to receive sunlight at different angles.

The angle at which the sun's rays strike the Earth affects the concentration of solar energy over a given area, influencing the amount of heating. When the sun's rays strike the Earth at a steeper angle (such as at noon), the energy is concentrated over a smaller area, resulting in more intense heating and higher temperatures. Conversely, when the sun's rays hit at a shallower angle (such as at sunrise or sunset), the energy is spread out over a larger area, leading to less intense heating and cooler temperatures.
As the angle at which the sun's rays strike the Earth's surface increases, the temperature tends to decrease. As the angle decreases, temperature tends to increase. At the same time, as the sun's angle decreases, shadows appear longer because the light is being cast at a greater angle.
During the winter season, the rays of the sun strike the Earth at a more oblique angle, causing them to spread out over a larger area. This results in less intense solar heating and shorter daylight hours, contributing to cooler temperatures. In contrast, during summer, the sun's rays strike more directly, leading to warmer weather.
In the tropics, near the equator, the sun's rays strike the Earth's surface at nearly a 90-degree angle, resulting in more direct and concentrated sunlight. This is why these regions receive more solar energy and experience higher temperatures compared to regions farther from the equator.
If the sun's rays hit the Earth's surface at a direct spot, which is usually around the equator, that area would be the warmest. Any area that is far away from the sun's rays is usually cold.
The angle at which the sun's rays strike the Earth's surface affects the intensity of the sunlight spread over a larger or smaller area, impacting the surface temperature. When the sun's rays hit the Earth at a higher angle (closer to perpendicular), the energy is concentrated over a smaller area, leading to higher temperatures. Conversely, when the angle is lower (closer to parallel), the energy is spread over a larger area, resulting in lower temperatures.
