How much solar energy is reflected by the atmosphere and earth's surface?
About 6% of incoming solar radiation is reflected back into space from the atmosphere and 4% by the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
How does changing a planet's albedo change a planet's temperature?
If you increase the albedo, more solar radiation will be reflected back into space and so the temperature will be lowered.
Why is the sun's radiation reflected back into space?
The sun's radiation is reflected back into space by the Earth's atmosphere, clouds, snow, ice, and other reflective surfaces. This reflection helps regulate the Earth's temperature by preventing excessive heating.
What two things can happen to electromagnetic energy that enters the earths atmosphere?
Electromagnetic energy that enters the Earth's atmosphere can be reflected back into space or absorbed by the atmosphere and surface. Absorption can lead to heating of the atmosphere and contribute to processes like the greenhouse effect.
What percentage of solar radiation reaches the earth and drives the hydro logic cycle?
About 50% of the incoming solar radiation reaches the surface of the planet. The rest is reflected or absorbed by the atmosphere & clouds, and a small portion is reflected by the oceans and land.
What electromagnetic radiation is an example of measuring the speed of a passing car?
Microwaves are an example of electromagnetic radiation that can be used to measure the speed of a passing car. This is commonly done using police radar guns, which emit microwaves and detect the frequency shift of the reflected waves to calculate the car's speed.
What is the role of electromagnetic radiatin in remote sensing?
Electromagnetic radiation is used in remote sensing to collect information about the Earth's surface and atmosphere. Different wavelengths of electromagnetic radiation interact with materials in unique ways, allowing scientists to identify and analyze various features and properties from a distance. By measuring the reflected or emitted radiation, remote sensing can provide valuable data for applications such as mapping, monitoring, and environmental assessment.
In what form is radiant energy reflected back into space?
Radiant energy is reflected back into space in the form of infrared radiation, which is a type of electromagnetic radiation. This process helps to maintain Earth's energy balance and regulates the planet's temperature.
How does electromagnetic radiation behave?
Electromagnetic radiation can behave either as a wave or a particle. A wave particle is duality. Electromagnetic energy results from acceleration of a charge EM radiation can travel through a medium or vacuum.
What happens to heat radiation when it neither passes through a material nor is reflected from it?
If heat radiation neither passes through a material nor is reflected from it, it is mostly absorbed by the material, leading to an increase in its temperature. This increase in temperature can result in the material emitting its own heat radiation in the form of infrared radiation.
What type of radiation is reflected away from the earths surface?
Visible light and infrared radiation are mainly reflected away from the Earth's surface. These wavelengths are absorbed by the atmosphere and then reflected back out into space, helping to regulate Earth's temperature.
What are the characteristics of electromagnetic radiation and how do they influence its behavior?
Electromagnetic radiation is a form of energy that travels in waves and does not require a medium to propagate. It has characteristics such as wavelength, frequency, amplitude, and speed. These characteristics determine how electromagnetic radiation behaves, including how it interacts with matter, how it is absorbed or reflected, and how it can be used in various applications such as communication, imaging, and energy generation.
How does electromagnetic radiation travel through different mediums?
Electromagnetic radiation can travel through different mediums by either being absorbed, transmitted, or reflected. The ability of a medium to allow electromagnetic radiation to pass through depends on its properties, such as density and composition. In general, materials like air and glass allow electromagnetic radiation to pass through easily, while materials like metal may block or reflect it.
When you measure the temperature of hot soup you are measuring the?
... amount of energy in the soup molecules.
What percentage of suns radiation is reflected by the earths surface?
About 30% of the sun's radiation is reflected back into space by the Earth's surface, clouds, and atmosphere. This reflection is known as albedo and helps regulate the Earth's temperature.
In which region of the electromagnetic spectrum is most of the outgoing radiation from earth?
Aside from all the radio signals generated by Man, the Earth radiates primarily in the Infrared portion of the electromagnetic spectrum. This consists of reflected and re-radiated solar heat and 'black body' radiation from the Earth itself. (The reflected radiation includes some components of shorter wavelength such as visible light, but the re-radiated component is essentially all infrared.)
Is the Rainbow an Radiation?
No, the rainbow is not radiation. It is a natural optical phenomenon that occurs when sunlight is refracted, reflected, and dispersed in water droplets in the Earth's atmosphere, creating a spectrum of colors. Radiation refers to the emission of energy as electromagnetic waves or particles.
