Twenty percent of the radiation from the sun refers to the portion of solar energy that reaches the Earth's atmosphere. This radiation includes visible light, ultraviolet light, and infrared radiation, which are essential for life on Earth. The remaining 80 percent is absorbed or scattered by the atmosphere before it reaches the surface. Ultimately, the radiation that reaches the Earth's surface is crucial for climate, weather patterns, and supporting ecosystems.

How big is the sun's radiation zone?

The radiation zone is the "middle part" of the interior of the Sun. It is adjacent to the core. In this zone, energy travels between the atoms as photons of gamma radiation. Above the radiative zone is the convective zone. Scientists estimate that core energy takes as long as 170,000 years to travel through the dense matter of the radiative zone.According to NASA, the Sun's radiative zone begins about 108,125 miles from the center of the Sun and ends about 302,750 miles from the center of the sun. So the radiative zone makes up 32 percent of the Sun's volume and 48 percent of its mass.The exterior of the Sun, where radiation again occurs, is called the photosphere. In some larger stars, the outer layer is radiative and is substantially thicker.


The atmosphere is heated chiefly by radiation emitted by Earth?

The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space. 20 percent is absorbed by clouds and the atmosphere's gases.


Why is 90 percent of the universe plasma?

because of the sun and it's radiation which also heats up the inner core


The atmosphere and clouds directly absorb about20 percent of the solar radiation that strikes earth How does the sun indirectly warm the atmosphere?

Earth's land and sea absorb solar radiation, then reradiate it to the air


How long does it take for radiation from the sun to reach the earth?

Distance from the earth to the sun is about 93,000,000 miles. The speed of light is about 186,000 miles/second or about 8 minutes, 20 seconds.

How does this radiation travel and how long does it take to reach earth after leaving?

Radiation from the Sun travels to Earth in the form of electromagnetic waves. It takes about 8 minutes and 20 seconds for this radiation to reach Earth after leaving the Sun.

How is the sun reflecting it radiation into space?

The sun does not reflect its radiation into space.


What happens to the heat sun?

This isn't the best answer, but it starts with 100% radiation, 25% is reflected back by clouds and other particles, 20% is absorbed by particles in the atmosphere, 50% of radiation reaches and is absorbed by Earth's surface, and 5% of radiation from the sun is reflected by land and sea surface.

What atmosphere filters out 95 percent of UV radiation?

The ozone layer in the Earth's stratosphere filters out about 95 percent of UV radiation from the sun. However, it is important to note that some UV radiation still reaches the Earth's surface, especially in areas where the ozone layer is depleted.


Is the sun drying wet on a sidewalk radiation?

Yes, the sun drying wet on a sidewalk is a form of radiation. The sun emits electromagnetic radiation, including infrared radiation, which can heat and evaporate water on the sidewalk.
