Answer:
D or B
Explanation:
It is around 77 degrees F
So I would say around 60
Answer:
mountain systems and fresh water
Explanation:
mountain systems are a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Take the Himalayan mountains for example.
Fresh waters are natural occurring waters except seawater and brackish water. for example they have lake Baikal,the Yangtze river etc.
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.
I believe the answer is either A or D. However, I think D sounds the most fitting but like i said, it could be either one. :)
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
