How do you know that heat travels from the sun to the earth by radiation?

It's the only way heat could reach us. It comes via electromagnetic radiation, discovered theoretically by James Clerk Maxwell. It can't come by conduction or convection because space is empty, there is no air there.

What travels around the sun in 365 days?
Oh, I don't know, maybe the earth?
How can solar heat system heat your house on a cloudy day?
there is always light coming from the sun, thus bringing forth heat. even though there are clouds, the light travels through clouds, bringing you heat.i cant believe you didnt already know this:)
Why can both the sun and earth be treated as blackbodies?
I don't know whether this is the case, but if it is so, that would mean that they absorb a large percentage of incoming radiation.
Transfer of heat through space?
Cleverly, that process is accomplished through the use of electromagnetic radiation.
Process by which earth's atmosphere traps heat?
The process by which earth's atmosphere traps heat is called the greenhouse effect :)
How is heat transferred within the earth's atmosphere?
Heat in earth's atmosphere is transferred by: Radiation, Conduction, & Convection. ((:
What are the two ways that heat travels?
Radiation,Convection and for a extra one conduction.For those of you who don't know condensation is not a way by which heat travels
How do you know that you receive heat from the sun by thermal radiation and not by conduction or convection?
Heat by radiation travels in a straight line (line of sight) from a hot body to cold body with no intervening fluid or material needed for heat conveyance. Thus if the cold body isn't blocked off from the hot body it will receive heat from it by radiation. Convection requires a fluid for heat conveyance, which doesn't exist between the sun and earth. Conduction requires contact for heat transfer.
What is similar to heat radiation?
We know that infrared radiation can transfer thermal energy (heat) from one place to another.
This type of radiation is normally felt as heat?
Any form of radiation can produce heat. Infra-red radiation is the most commonly recognized as heat, but the question has a much longer answer if you need to know the why.
What is heat radiation also known as?
well I'm not a genius but i think i know another word for heat radiation is thermal radiation. but hey I'm not the computer.
The primary method of energy transfer by which Earth loses energy to outer space is?
Earth loses energy to outer space through radiation.
Where does radiation take place?
this answer is really hard to find and I think radiation takes place in hospitals in case of some x-rays, in the space for sun's heat to travel through to earth as I am small and in grade seven I may not know much
How can you know that light travels through a vacuum?
light travels from sun to earth through vaccum, so its easily understood
Why are refrigerator compressors painted black?
It's because of radiation that as you know black body is an ideal radiation body for good radiation and so good heat transfer.
How can heat radiation be prevented?
by insulating heat producing system from 4 sides will reduce radiation. and that insulator should be in dark colour, because we know that dark bodies absorb radiations easily.
How do you know that heat is transferred from the sun to earth by radiation?
It cannot be transmitted by conduction nor convection because there is no material connection between the sun and the Earth. Conduction and convection need a medium through which to travel, and since the space between the Earth and the Sun is considered a vacuum, they cannot occur. However, radiation does not require a medium through which to travel. It can travel through a vacuum, and therefore space. Therefore, it's the only surviving option for heat transmission.
