How Does Radiation Affect The Atmosphere


How Does Radiation Affect The Atmosphere?


Larger aerosol particles in the atmosphere interact with and absorb some of the radiation causing the atmosphere to warm. The heat generated by this absorption is emitted as longwave infrared radiation some of which radiates out into space.

How does radiation work in the atmosphere?

Most of the solar radiation is absorbed by the atmosphere and much of what reaches the earth’s surface is radiated back into the atmosphere to become heat energy. Dark colored objects such as asphalt absorb radiant energy faster than light colored objects.

How does radiation affect climate?

Researchers have shown that UV radiation affects climate through direct heating and the production and destruction of ozone in the stratosphere which then leads to regional effects at Earth’s surface through a complex chain of mechanisms.

How does radiation interact with matter in the atmosphere?

Particles and gases in the atmosphere can affect the incoming light and radiation. … Scattering occurs when particles or large gas molecules present in the atmosphere interact with and cause the electromagnetic radiation to be redirected from its original path.

What is solar radiation and how does it affect our atmosphere?

Solar radiation is the energy emitted by the Sun which is sent in all directions through space as electromagnetic waves. Emitted by the surface of the Sun this energy influences atmospheric and climatological processes.

How do radiation conduction and convection affect the atmosphere?

Convection is the transfer of heat energy in a fluid. Air in the atmosphere acts as a fluid. The sun’s radiation strikes the ground thus warming the rocks. As the rock’s temperature rises due to conduction heat energy is released into the atmosphere forming a bubble of air which is warmer than the surrounding air.

What happens when solar radiation enters Earth’s atmosphere?

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.

How much radiation is in the atmosphere?

Background dose rate examples

Cosmic radiation from space 0.39 depends on altitude

When solar radiation falls on Earth’s atmosphere the temperature of land mass?

Absorption of solar radiation by ozone shields the terrestrial surface from harmful ultraviolet light and warms the stratosphere producing maximum temperatures of −15 to 10 °C (5 to 50 °F) at an altitude of 50 km (30 miles).

How does radiation interacts with the objects in the surface of the earth?

Radiation that is not absorbed or scattered in the atmosphere can reach and interact with the Earth’s surface. … These are: absorption (A) transmission (T) and reflection (R). The total incident energy will interact with the surface in one or more of these three ways.

How do we interact with the atmosphere?

Human and societal actions such as globalization urbanization energy conversion technologies emission control policies land-use change as well as various natural feedback mechanisms involving the biosphere and atmosphere have substantial impacts on the complicated couplings between atmospheric aerosols trace …

How do the interactions in the atmosphere affect human lives?

In more subtle ways atmosphere-biosphere interactions influence the health of the air we breathe (see figure): rough surfaces of vegetation remove aerosols ozone and other reactive gases from the air through dry deposition plants emit a huge variety of volatile organic compounds (VOCs) that are precursors to …

What is the atmospheric effect?

1. the tendency for particular behaviors to be stimulated by a particular environment or situation even when inappropriate such as gesturing when using the telephone or applauding a poor speech. 2.

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 are the 4 main effects of solar radiation on Earth?

Solar Radiation at the Earth’s Surface
  • atmospheric effects including absorption and scattering
  • local variations in the atmosphere such as water vapour clouds and pollution
  • latitude of the location and.
  • the season of the year and the time of day.

How does convection affect Earth’s atmosphere?

How does convection affect the weather? Convection within the atmosphere can often be observed in our weather. … Stronger convection can result in much larger clouds developing as the air rises higher before it is cooled sometimes producing Cumulonimbus clouds and even thunderstorms.

How does global warming affect the atmosphere?

More frequent and severe weather

Higher temperatures are worsening many types of disasters including storms heat waves floods and droughts. A warmer climate creates an atmosphere that can collect retain and drop more water changing weather patterns in such a way that wet areas become wetter and dry areas drier.

How does radiation heat up the atmosphere for Class 6?

Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. … Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions including downwards and thereby trapping heat in the atmosphere.

What type of radiation enters the atmosphere from the Sun?

shortwave radiation
Solar energy enters our atmosphere as shortwave radiation in the form of ultraviolet (UV) rays (the ones that give us sunburn) and visible light. The sun emits shortwave radiation because it is extremely hot and has a lot of energy to give off.

How does Earth’s atmosphere protect us from the Sun’s radiation?

Gases in Earth’s atmosphere form a protective layer

Nitrogen oxygen and ozone molecules in the upper atmosphere and stratosphere absorb ultraviolet light from the Sun providing a shield that prevents this radiation from passing to the Earth’s surface.

What kinds of changes to the atmosphere would affect how much energy is absorbed by Earth’s surface?

Because temperature increases when there is more total energy which means more energy gets absorbed by Earth’s surface the increase in carbon dioxide from volcanic eruptions leads to warmer temperatures on Earth.

What radiation does the atmosphere stop?

X-ray/gamma ray radiation

The Earth’s magnetosphere protects us here on Earth from the effects of the plasma keeping it safely away from the surface of the planet. And our atmosphere keeps the X-ray/gamma ray radiation out.

Which is the most harmful radiation entering the atmosphere of Earth from outer space?

Answer: High energy ultraviolet radiation.

What are the effects of space radiation?

The major concern about space radiation is the long term effects on astronauts. Long term effects can include cataracts increased chance of cancer and sterility. Some health effects can skip a generation and appear in the descendants of the exposed individual being passed on by mutated genes.

How does radiation affect evaporation?

Solar radiation and temperature are closely related and as temperature increases the energy content of water molecules increases making them more likely to diffuse into the air. Also warmer air has a greater capacity to hold water vapor. … This results in higher water temperature and favors greater evaporation.

Does solar radiation affect air stability?

It is due to the fact that air temperature is directly related to the global solar radiation. So increase in solar radiation increases the air temperature.

What radiation reaches the Earth’s surface?

Most of the solar radiation that reaches Earth is made up of visible and infrared light. Only a small amount of ultraviolet radiation reaches the surface.

How does the energy from the sun interacts with the atmosphere?

The atmosphere also interacts with incoming radiation through a process called molecular scattering. Light rays are very small. … As the light comes from the Sun these small molecules scatter the light. Scientists call it Rayleigh scattering.

Which type of electromagnetic radiation emitted by the sun are absorbed by Earth’s atmosphere and does not reach Earth’s surface?

UV-C rays

Luckily UV-C rays do not reach the earth’s surface because of the ozone layer. When UV-C rays meet the ozone molecules at high layers of the atmosphere the energy inherent in them is enough to break apart the bond of the molecule and absorb the energy.

Does radiation reflect?

In diffuse reflection radiation is reflected equally in all directions. Reflection from smooth and polished surfaces can be assumed to be specular reflection whereas reflection from rough surfaces approximates diffuse reflection.

What are 2 examples of how atmosphere affect the conditions on our planet?

The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation keeping the planet warm through insulation and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.

How does the atmosphere interact with the other Earth systems?

The atmosphere brings back rainwater to the hydrosphere. … The atmosphere provides the geosphere with heat and energy needed for rock breakdown and erosion. The geosphere in turn reflects the sun’s energy back into the atmosphere. The biosphere receives gases heat and sunlight (energy) from the atmosphere.

How do atmosphere affect the flow of matter and energy on Earth?

The atmosphere receives energy from solar radiation which warms the earth’s surface and is re-emitted and conducted to the atmosphere. The atmosphere also absorbs water from the earth’s surface via the process of evaporation it then acts to redistribute heat and moisture across the earth’s surface.

What will happen if the atmosphere on earth is removed?

The air would still be too thin to breathe. The lack of atmosphere would chill the Earth’s surface. We’re not talking absolute zero cold but the temperature would drop below freezing. Water vapor from the oceans would act as a greenhouse gas raising the temperature.
