How does the heat move through the space between the sun and the earth? match the heat transfer mechanisms in space and on earth with the correct description.

the choices are
1. electromagnetic waves transfer energy through space to earth
2. heat energy on earth escapes into space
3. moves from warmer to cooler
4. touching, direct contact
5. warm air circulates towards cooler polar regions
6. flow of heat energy through liquids and gases
7. heat energy transferred
8. responsible for weather patterns on earth
9. transfer of heat through soil by the movement of molecules
10. warm air in atmosphere rises and is replaced by cooler air

Conduction- 4 and 9

All - 3 and 7

Convection- 5, 6, and 10

Convection & Radiation-8

Radiation-1 and 2

nothing for Conduction & Convection

Explanation:

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
