What causes the surface of the sun to emit light and heat?
the causes
The process by which heat from the sun builds up near the earth's surface and is trapped by the atmosphere?
Greenhouse effect
How much light and warmth a planet receives depends on what?
A planet's proximity to the Sun affects how much light and warmth it will receive. In addition to its distance from the Sun, surface reflectivity as well as the planet's atmosphere or greenhouse effect. Light from the Sun will either be reflected back into space or make it to the ground to heat it up.
Why do houses in Egypt have light coloured roof?
If it were a dark colour, it would attract too much heat.
What is the trapping of heat near a planet's surface by certain gases in the planet's atmosphere?
We call it the greenhouse effect, which is natural, or the enhanced (or accelerated) greenhouse effect which is causing global warming.
Do dark or light surfaces attarct and absorb heat easier?
A dark surface will absorb the heat from sunlight. While a white surface will reflect a lot of the sunlight and remain cooler.
Why dark surface is a good emitters of heat?
The dark surfaces heat up faster because dark surfaces attract sunlight faster than light surfaces.
Why is it the darker the surface will have the higher temperature?
A dark surface will absorb the heat and reach a higher temperature. A light surface will reflect most of the heat and become cooler.
Why the top surface of the reflecting hood should be a lightly shiny surface rather than a dark Matt?
Dark, matt surfaces absorbs more heat. It should be a light, shiny surface as it doesn't absorb as much heat and not overheat it.
What is the effect of a eclipse?
It gets dark and cold(because there isn't any light or heat from the sun)
Do dark surfaces absorb more heat than light or reflective surfaces?
Because darker surfaces need more light because it's a dark surface
Does dark skin and not just dark colors attract more light and cause warmth?
Dark and light surface's gain heat through the absorption of radiation. Light that would normally bounce for a light colored surface, say yellow, is absorbed by a darker color, say purple. The extra energy that is absorbed by the darker surface causes an increased temperature when compared to one another. Skin as the surface has no bearing on the process.
Does the interior color of a car effect the inside temperature?
Yes it can as dark and light colors absorb and reflect light. The darker the more it absorbs light and heat energy.
Does color affect heating by absorption of light?
yes it does if the material is dark it will be warm if it is light it will be colder Yes, darker colors generally absorb AND RADIATE more heat from radiated. Meaning that if there is plenty of radiated heat available for example from the sun, dark clors will absorb more. If it's dark and cold out and the surface is hot, a dark surface will also RADIATE more heat than a lighter colored surface. It's called "black-body radiaton."
Do dark or light colors attract more heat?
dark colours attract more heat than the light ones, the light colours reflect heat mainly
Does color have effect on evaporation?
Dark colors absorb more light and therefore build up more heat, speeding evaporation.
Do dark rocks absorb more heat than light rocks?
Dark rocks will absorb more radiant heat than light rocks, for the same reason that any dark object absorbs more heat than an equivalent light object. Light objects appear "light" to us because they reflect more light than objects which appear dark. Dark objects appear dark because they absorb more light and reflect less. However, dark objects will radiate more heat that light objects. Actually, dark rocks do NOT absorb more radiant heat than light rocks. Nor do they radiate more heat than light rocks. Dark rocks DO absorb more LIGHT than light rocks and they then radiate this light at heat. Light rocks reflect the light rather than absorb it and therefore do not radiate as much heat. If you put a light rock and a dark rock next to a HEAT source, the amount of heat absorbed will be related to the makeup of the material rather than to the color.
