What happens to solar energy that is reflected by Earth’s surface?

Some of the sun’s energy is reflected back to space by clouds and the earth’s surface. … The absorbed energy is transformed into heat energy. This heat energy plays an important role in regulating the temperature of the earth’s crust, surface waters, and lower atmosphere.

What happens to the solar energy that reaches Earth’s surface?

The energy that reaches the Earth’s surface (primarily visible light) is absorbed by the Earth. This increases the temperature of the Earth and then that absorbed energy is released as heat.

What happens to the solar radiation that is reflected?

Roughly 30 percent of the total solar energy that strikes the Earth is reflected back into space by clouds, atmospheric aerosols, snow, ice, desert sand, rooftops, and even ocean surf. The remaining 70 percent of the TSI is absorbed by the land, ocean, and atmosphere.

How is solar energy absorbed by Earth’s surface?

About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.

How does solar energy affect Earth’s atmosphere and surfaces?

The radiation warms the Earth’s surface, and the surface radiates some of the energy back out in the form of infrared waves. As they rise through the atmosphere, they are intercepted by greenhouse gases, such as water vapor and carbon dioxide. Greenhouse gases trap the heat that reflects back up into the atmosphere.

What happens to energy that does not reach Earth’s surface?

When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth’s surface. … The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space.

What is solar radiation reaching the Earth’s surface?

The solar radiation that reaches the Earth’s surface without being diffused is called direct beam solar radiation. The sum of the diffuse and direct solar radiation is called global solar radiation. Atmospheric conditions can reduce direct beam radiation by 10% on clear, dry days and by 100% during thick, cloudy days.

When Earth’s surface radiates some energy back into the atmosphere it is in what form?

Effect on Surface Temperature

On average, 340 watts per square meter of solar energy arrives at the top of the atmosphere. Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy).

What is the term for the total radiation that is reflected by a surface?

Albedo. the fraction of total radiation that is reflected by any surface.

Why does the amount of solar energy received at Earth’s surface change when the angle of the sun changes?

Answer: When sunlight shines on the Earth at a lower angle (Sun closer to the horizon), the energy of the sunlight is spread over a larger area, and is therefore weaker than if the Sun is higher overhead and the energy is concentrated on a smaller area.
