Contrast the amount of direct sunlight received by an area near the equator and a same sized area near the South Pole. They receive the same amount of direct sunlight throughout the year, it’s just divided up differently.

The area at the equator receives more direct sunlight than the area at the pole because Earth’s tilt doesn’t affect the area at the equator.

The poles receive more direct sunlight than the area around the equator because they receive 24 hours of daylight at times during the summer.

There is not enough data to answer this question.

the total distance traveled by the car is

30km + 49km = 79 km .

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.
