It averages out to about 1 kilowatt per square metre, for a surface
perpendicular to the Sun's rays at sea level on a clear day.
The Earth. In a lunar eclipse, the Earth's shadow blocks sunlight from hitting the Moon.
The three main influences on the input of solar energy to the Earth are the distance between the Earth and the Sun, the angle at which the sunlight reaches the Earth's surface (known as the solar angle), and the amount of atmosphere the sunlight has to travel through before reaching the Earth's surface. These factors determine the intensity and distribution of solar energy received by different parts of the Earth.
Approximately 1-2% of the solar energy reaching Earth is absorbed and converted into chemical energy through photosynthesis. This process primarily occurs in plants, algae, and some bacteria. The remaining solar energy is either reflected back into space, absorbed by the atmosphere and oceans, or used in other ecological processes, such as heating the Earth's surface and driving weather patterns.
Yes, the solar constant affects temperature by determining the amount of solar energy reaching the Earth's atmosphere. A higher solar constant can lead to an increase in temperature, while a lower solar constant can result in cooler temperatures.
The most important factors affecting the input of solar energy to Earth are the Earth's axial tilt, distance from the sun, and the presence of atmospheric components such as clouds, dust, and greenhouse gases. These factors influence the amount of solar radiation reaching the Earth's surface, which in turn affects climate patterns and overall energy balance on our planet.

The amount of solar energy reaching Earth is primarily controlled by three factors: the Earth's distance from the Sun, which varies due to its elliptical orbit; the Sun's output, which can fluctuate due to solar cycles; and the Earth's atmosphere, which can absorb or reflect solar radiation. Additionally, clouds and aerosols can influence how much solar energy reaches the surface. Together, these factors determine the overall solar radiation received by the planet.
Roughly 30% of the incoming solar energy is reflected back to space by clouds, the atmosphere, and the Earth's surface. Another 20% is absorbed by the atmosphere and clouds before reaching the Earth's surface, leaving only about 50% to be absorbed by the Earth's surface.
The primary factors that determine the amount of solar energy reaching places on Earth are: the angle of sunlight hitting the Earth's surface (affected by time of day and latitude), the length of daylight hours (affected by season and location), and atmospheric conditions (cloud cover, pollution) which can absorb or scatter sunlight.
Solar energy reaches Earth in the form of sunlight. It is emitted by the sun as electromagnetic radiation and travels through space before reaching our planet. This sunlight carries energy that can be harnessed using solar panels to generate electricity.
The polar regions receive the least solar energy due to their high latitudes and the angle at which sunlight strikes the Earth's surface. This leads to long periods of darkness during the polar winter, resulting in minimal solar energy reaching these areas.

These factors determine the intensity and distribution of solar energy received by different parts of the Earth.
Clouds are not an energy source themselves, but they can affect the amount of solar energy reaching the Earth's surface by reflecting, absorbing, and scattering sunlight. This can impact the overall availability of solar energy for technologies like solar panels.
Nothing. Provided the earth remains in the same orbit, then a change of rotation would not change the amount of solar energy reaching the earth.
There are several factors that contribute to the decrease in the amount of energy reaching earth's surface. These are: reflection, scattering, absorption by gases and aerosols in the atmosphere, and cloud cover.
