When sunlight strikes Earth, approximately 30% is reflected back into space by clouds, atmospheric particles, and the Earth's surface. The remaining 70% is absorbed by the atmosphere, oceans, and land, which helps to drive the planet's climate and weather systems. This balance is crucial for maintaining life on Earth.
That varies from almost zero (black surfaces) to all of it (white & shiny surfaces).
47% heavy.
It takes light around 8 minutes and 19 seconds to reach the earth from the sun.
Approximately 20 percent of the Earth's atmosphere is made up of oxygen.
53 percent of Earth's diameter is approximately 6,465 kilometers.
The Earth's layer that sunlight strikes first is the ozone layer.
That varies from almost zero (black surfaces) to all of it (white & shiny surfaces).
The angle at which sunlight strikes Earth's surface varies depending on the time of day and the location on Earth. When the Sun is directly overhead, the sunlight strikes the surface at a 90-degree angle, which maximizes the intensity of the sunlight. As the Sun moves lower in the sky, the angle of sunlight decreases, leading to greater dispersion of sunlight and lower intensity.
When sunlight strikes the Earth, it provides energy for photosynthesis in plants, warms the planet's surface, and drives the Earth's weather patterns and climate. Sunlight also stimulates the production of vitamin D in human skin and provides illumination for various organisms to carry out their daily activities.
The phases are caused by the angle that the sunlight strikes the moon.
Landmasses occupy approximately 29 percent of the Earth's surface.
Sunlight reaches the surface of the Earth at all points where there is daylight. The distribution of sunlight on Earth varies throughout the day due to the rotation of the Earth on its axis.

The mass percent of oxygen is approximately 21% in Earth's atmosphere.
The more acute the angle at which the sunlight strikes, the more atmosphere that sunlight must pass through. Passing through more atmosphere will weaken and dim the light beams. As the angle at which sunlight hits the earth changes, the same amount of sunlight is spread over different areas, so that near the poles each area of surface receives less intense radiation than an equivalent area near the poles.
