Once the sun’s energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun’s energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun’s energy is reflected back to space by clouds and the earth’s surface.
What happens to solar energy as it enters Earth’s atmosphere?
Energy released from the Sun is emitted as shortwave light and ultraviolet energy. 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.
What happens to solar energy when it reaches Earth’s atmosphere quizlet?
What happens to the solar energy that is not absorbed by Earth’s surface? It is absorbed or reflected by clouds, gasses, and dust, or is reflected off of Earth’s surface. … Because oceans and land radiate the energy, that they have absorbed, back into the atmosphere.
What three things can happen to solar energy as it enters Earth’s atmosphere?
Solar power drives Earth’s climate. Energy from the sun heats Earth’s surface, warms the atmosphere, provides energy for photosynthesis, causes evaporation, drives the weather and water cycles, and powers the ocean currents.
How much solar energy reaches the Earth?
When absorption and scattering are taken into account, the total solar flux reaching the surface of the earth is estimated to be 1.08×108 GW and the total amount of energy reaching the surface of the earth each year is 3,400,000 EJ. This is between 7000 and 8000 times annual global primary energy consumption.
How much sunlight reaches the Earth’s surface?
The atmosphere absorbs 23 percent of incoming sunlight while the surface absorbs 48. The atmosphere radiates heat equivalent to 59 percent of incoming sunlight; the surface radiates only 12 percent.
Why does earth’s surface not get hotter and hotter?
The Earth does not continue to get hotter and hotter as it absorbs energy from the sun, because it gives off energy to space as invisible infrared radiation. … The amount of infrared radiation energy the Earth gives off depends on its temperature.
Which of the following does not happen to solar energy when it reaches Earth?
Which of the following does NOT happen to solar energy when it reaches Earth? … The cooling of Earth due to air pollution. The heating of a solid, such as a rock.
What is the only thing that enters the Earth’s atmosphere from the sun?
Meteoroid: A small particle from a comet or asteroid orbiting the Sun. Meteor: The light phenomena which results when a meteoroid enters the Earth’s atmosphere and vaporizes; a shooting star. Meteorite: A meteoroid that survives its passage through the Earth’s atmosphere and lands upon the Earth’s surface.
What happens to the scattered insolation as it reaches Earth?
Terrestrial Radiation – Once insolation is absorbed by the Earth’s surface, it eventually gets re-radiated back into the atmosphere or into space. … Some of this infrared radiation is trapped by gases in the atmosphere. This helps to heat the atmosphere and the planet. This effect is called the greenhouse effect.
What happens when sunlight reaches the Earth?
The Sun provides the Earth with most of its energy. Today, about 71% of the sunlight that reaches the Earth is absorbed by its surface and atmosphere. Absorption of sunlight causes the molecules of the object or surface it strikes to vibrate faster, increasing its temperature.
Can the sun power the Earth?
In a single hour, the amount of power from the sun that strikes the Earth is more than the entire world consumes in an year. To put that in numbers, from the US Department of Energy: Each hour 430 quintillion Joules of energy from the sun hits the Earth.
