Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
Answer:
Option C is correct.
Folding.
Explanation:
In Geography, folding is a process whereby rock layers bend due to compressional forces.
Just as described in the question above, compressional forces mean that the two ends of the rock layers are being pushed inwards towards each other. The rock layer, just like the cloth layer described above, responds by bending or rumpling.

Answer:
So much salt will be left that is even enough to form a layer about 500 feet thick that covers all of Earth.
