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.
It would probably be hail since big blocks of ice could easily break the power lines
The answer is C “volcanic activity was more common in the past than it is today
The answer is B. An increase in manufacturing :)
The correct answer is - Greenhouse effect.
The Greenhouse effect is a process in which certain type of gasses in the lower atmosphere manage to trap the heat that is radiated from the surface of the planet.
The gases that are considered to be greenhouse gases are able to perform such a thing, despite being relatively low in amount compared to other gases, because they have much more complex molecular structure.
The molecular structure of this gases enables them to trap the heat, or rather to not allow to leave the atmosphere and return it back toward the surface, thus having huge effect on the climate.
Greenhouse gases are the carbon dioxide, methane, water vapor, nitrous oxide.
