The atmosphere is heated chiefly by radiation emitted by Earth?
The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space. 20 percent is absorbed by clouds and the atmosphere's gases.
Why is the stratosphere cold?
The stratosphere is cold because it is heated from below by the Earth's surface but does not have direct contact with the surface, so it lacks a significant source of heat. Additionally, the stratosphere contains ozone molecules that absorb and redistribute incoming solar radiation, leading to a temperature increase with altitude.
Why does the thermosphere have the highest temperature out of all the other layers?
The thermosphere is heated by solar radiation particularly in the far ultraviolet range; much of this is filtered out by the atmosphere's lower layers - but in the these upper regions it is more exposed to this kind of radiation.
Does the sun have the ability to support life?
No. Even the "coldest" parts of the sun are heated to thousands of degrees and subjected to intense radiation. Nothing could live there.
When water is heated in the atmosphere what does it do?
If you're talking about the basic water cycle, starting in the ocean, water evaporates into vapor (Evaporation) rising up until it reaches it's the dew point, then the water condenses and travel towards higher ground, sometimes it travels as far as sea level ground (Condensation), when it reaches that heavy point where the clouds is too heavy to carry the water it drops taking about 10-15 minutes from the clouds to reaches the surface of the Earth if clouds are in the strato zone (Precipitation).
If clouds absorb only a small amount of solar radiation how is Earth's atmosphere heated?
The Earth's atmosphere is primarily heated through the process of re-radiation, where the Earth's surface absorbs incoming solar radiation and then releases it as heat energy. This heat is then trapped within the atmosphere by greenhouse gases like carbon dioxide, water vapor, and methane, resulting in an overall warming effect. While clouds do reflect some solar radiation back into space, they also play a role in trapping heat through their greenhouse effect.
Can gases emit radiation?
Yes, gases can emit radiation. When a gas is heated, it can emit thermal radiation in the form of light. Additionally, certain gases can absorb and emit specific wavelengths of radiation, such as in the process of fluorescence or phosphorescence.
What happens to air heated by radiation?
When air is heated by radiation, the air molecules absorb the radiant energy and increase in kinetic energy, causing them to move more vigorously. This increased motion leads to expansion of the air, resulting in a rise in temperature.
What type of substance is heated by radiation?
Any substance that absorbs the radiation is heated by it.
Is the land heated by convection?
I think the land is heated by radiation
The atmosphere is heated chiefly by radiation emitted by Earth?
The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space. 20 percent is absorbed by clouds and the atmosphere's gases.
Why is a sandy shore hot on a summers day?
the sand is heated through radiation.
What is it called when the earth is heated by the sun?
Radiation
How are convection and radiation?
They can be heated by 2 objects
Radiation require a heated liquid to transfer energy?
Radiation does not require a medium like a heated liquid to transfer energy. Radiation can transfer energy through electromagnetic waves, such as light or infrared radiation, and can travel through a vacuum. Heat transfer by radiation relies on the emission and absorption of electromagnetic waves between objects.
What is heated by radiation?
Radiation is a method of heat transfer that does not rely on any contact between the heat source and the heated object (as is the case with convection and conduction) Examples of radiation is heat from the sun or from the fliament of a light bulb
How are the bricks beneath a fireplace heated by the flames?
At first, they may be heated by radiation- heat radiated by the fire. As the fire burns, and ashes build up, they will be heated by conduction- heat conducted (poorly) through the ash to the bricks.
