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 passes through Earth’s atmosphere?
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.
What three things can happen to solar energy as it enters Earth’s atmosphere?
Once energy from the Sun gets to Earth, several things can happen to it:
- Energy can be scattered or absorbed by aerosols in the atmosphere. …
- Short wavelengths are absorbed by ozone in the stratosphere.
- Clouds may act to either reflect energy out to space or absorb energy, trapping it in the atmosphere.
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.
Does atmosphere affect solar energy?
While the absorption by specific gasses in the atmosphere change the spectral content of the terrestrial solar radiation, they have a relatively minor impact on the overall power. Instead, the major factor reducing the power from solar radiation is the absorption and scattering of light due to air molecules and dust.
How does energy flow in and out of Earth’s atmosphere?
In the atmosphere, greenhouse gas molecules absorb this thermal energy, and their temperatures rise. After this absorption, the gases radiate thermal energy back out in all directions. This thermal energy then radiates back out into space.
What four things happen to solar energy on Earth?
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.
What part of the Earth receives the most solar energy?
The sun’s rays do not strike the Earth’s surface as directly at the North Pole; they are less focused. The equator receives the most solar radiation in a year. The difference in the amount of solar energy the land receives causes the atmosphere to move the way it does.
What happens to most solar radiation when it reaches the surface of the Earth quizlet?
What happens to solar radiation after it reaches Earth? … – Nearly 70% of solar radiation is absorbed by the earth’s atmosphere and oceans, and the rest is reflected back into space. The absorbed radiation is re-emitted as infrared radiation.
How does the Earth release energy back into the atmosphere quizlet?
When Earth’s surface is heated, it radiates most of the energy back into the atmosphere as infrared radiation. Much of this energy is held by the atmosphere, warming it. … radiation, conduction, and convection.
How much of the solar energy that reaches Earth’s atmosphere is either scattered or reflected?
1.3 Energy Incident at Earth’s Surface
Of the roughly 56% of the incoming solar radiation making it through the atmosphere to Earth’s surface, about 6% gets reflected by the surface and 50% is absorbed at the surface.
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 is the effect of atmosphere in the Earth?
Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.
What happens to sunlight that hits Earth’s surface?
what happens to sunlight that hits Earth’s surface? the sunlight is absorbed by Earth’s surface and then the light is reflected back by Earth’s surface.
