it is estimated that it takes approximately 8 mins for light for the sun to reach the earths crust
that's actually the equator
The tilt of Earth's axis causes the angle at which sunlight hits the surface to vary throughout the year, leading to seasonal changes in temperature. When a hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences summer; when tilted away, it receives less direct sunlight and experiences winter. This variation in sunlight angle influences the distribution of heat on Earth's surface.
The amount of sunlight reaching a location at a particular time is determined by Earth's shape, axial tilt, rotation, and orbit around the sun. These factors affect the angle at which sunlight hits the Earth's surface, leading to variations in day length and intensity of sunlight throughout the year.
At any given time, half (50%) of Earth is exposed to sunlight.
if there was no sunlight life on earth would not survive for very long.
Sunlight that hits the Earth's surface is absorbed by the Earth. It is then reflected back.
The angle of incidence refers to the angle at which sunlight hits the Earth's surface. When sunlight hits the Earth's surface at a higher angle of incidence (more direct sunlight), the energy from the sunlight is more concentrated, leading to increased heating of the surface. This can result in higher temperatures on Earth.
that's actually the equator
warmer of course
The moon does not generate its own light. Instead, it reflects sunlight that hits its surface back towards Earth. This reflected sunlight is what we perceive as moonlight.
The moon is lit by sunlight just like the earth. Because of it's rotation relative to the earth, only one face of it is visible to people on earth. Thus, the expression, "the dark side of the moon". When the Earth is between the Sun and the moon, it is more or less invisible, since no direct light is striking it. We call this period of a few days a "new moon".
About 35% of the light that hits the Earth is reflected away immediately, back into space. The remainder of the light hits the Earth. Some of it is absorbed or scattered in the atmosphere, and much of it reaches the surface as light. Sunlight that is absorbed by the surface heats the Earth.
When sunlight hits Earth at an angle smaller than ninety degrees, the energy is spread over a larger surface area, resulting in less energy per unit area. This leads to lower intensity of sunlight and reduced heating compared to when sunlight hits directly overhead.
When a ray of sunlight hits Earth's atmosphere, it undergoes several processes, including scattering, absorption, and reflection. Some of the light is scattered in different directions by air molecules and particles, contributing to the blue color of the sky. A portion of the sunlight is absorbed by gases and aerosols, which helps heat the atmosphere. The remaining sunlight reaches the Earth's surface, providing the energy necessary for life and driving weather patterns.
A little known fact is that the angle that sunlight hits the different parts of the earth determines how hot or cold that region is. Because the world is round and tilted at a 23.5 degree angle, at different times of the year different parts of the world have more direct sunlight. Observe the picture below:As you can see in the north the angle of the earth results in the sunlight coming in at a very shallow angle and therefore cannot be absorbed very well. However, going toward the center of the earth the light hits the earth at sharper and sharper angles, which causes more heat to be captured and stored.So, in short, the further north or south you go, the shallower the angle that sunlight hits the earth causing those regions to be cooler (on average) and the further toward the equator you go, the sharper the angle that sunlight hits the earth causing those regions to be warmer (on average).
About 174 Petawatts of solar energy from the sun hits the Earth in the form of sunlight.
It results in seasons, also did you know when it is winter, you are closer to the Earth then in winter,but because of the angle less sunlight hits you.
