Taphonomy is the study of what happens to animals or humans between the time that they die and the time that their remains are found.

True.

Explanation:

The formation of fossils is associated with a series of biological and geological events beginning with the death of an organism. This is followed by a series of events, such as necrolysis, disarticulation, transport and burial of the remains, until the final occurrence of the physicochemical processes that transform sediments into rock and fossilize the organisms deposited therein. The area of paleontology that deals with unraveling all the processes mentioned above is taphonomy. With that we can say yes, Taphonomy is the study of what happens to animals or humans between the time they die and the time their remains are found.

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.
