I have no idea, but I wouldn't use Wikipedia.. The "facts" on there aren't always true. That's why we aren't allowed to use it in my high school.
Answer: I believe that all of those are correct answers.

Answer:
Explained
Explanation:
The melted magma or partially melted rock rise or intrude the surrounding rocks because of the buoyancy. The partially melted rocks or magma due their high temperature become less dense than the surrounding rocks and rise up. And then these heated rock or magma react with surrounding rocks which in turn increases the pressure in the magma chamber. This intermixing of magma with surrounding rocks forms another type of rocks called igneous rocks.
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.
