a) A lens has to be supported only around its edges.
b) Only the front surface of a mirror has to have a precise shape.
c) Reflecting telescopes have shorter focal lengths than refracting telescopes.
d) It is easier to make a large reflecting telescope than a large refracting telescope.
e) Lenses are not subject to chromatic aberration.
f) A reflector can collect more light than a refractor.
Answers
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 is simpler to make a large reflecting telescope than have a large refracting telescope. A reflector can collect more light than a refractor. Hence the options D and F are correct.
What are professional telescopes ?A telescope is an optical instrument that is used for seeing far objects from a distance and includes the measures for the various distances that can be used to see through the device. The light that is emitted, absorbed, and reflected can be seen through the electromagnetic radiation can be observed through the refracting lens of the telescope.

Which type(s) of rock can be the source of deposited sediments?
Answers
Answer:
Breccia, conglomerate, sandstone, siltstone and shale.
Sandstone, limestone, and shale of rock can be the source of deposited sediments.
What are deposited sediments?Sediments is the setting down of residue conveyed by wind, streaming water, the ocean, or ice. Silt can be shipped as rocks, sand, and mud, or as salts disintegrated in water. Salts may later be kept by natural action or by vanishing.
Sedimentary rocks are one of three principal sorts of rocks, alongside molten and transformative. They are shaped on or close to the World's surface from the pressure of sea dregs or different cycles.
Sedimentary rocks are framed on or close to the World's surface, as opposed to transformative and molten rocks, which are shaped profoundly inside the Earth. The deposit was the one that will be present. There will be different types of deposition that will be available with time.

4. The total process of land surface reduction is termed:
Answers
Answer:
22.1 erosion is termed as the total land surface reduction.
The total process of land surface reduction is termed Erosion. It is the process through which the land surface is eroded by the force of gravity alone, wind, water, or ice.
What is Soil Erosion?When water or wind impact separates and removes soil particles, the soil deteriorates gradually as a result of soil erosion.
Although soil erosion may seem insignificant, it eventually fills in waterways and lakes. Without a doubt, erosion brought on by water causes the most harm. Exposed soils get separated during rain and are carried by run-off. Such erosion not only looks bad, but it also harms the ecology by contaminating the nearby lakes, rivers, and streams with silt and sand. Filling of stream bottoms reduces the amount of water a stream can transport while eliminating natural habitat. This filling eventually reduces the capacity of drinking water reservoirs and causes properties upstream to be swamped by floodwaters.
Therefore, The total process of land surface reduction is termed Erosion.

Answers
The most deposition will be found at Point A and Point B.
What is the relationship between deposition and speed of water flow?There is an inverse relationship between rate of deposition and rate of speed of water flow. That is, when water flows at lower speeds, it allows for deposition of particles, compared to higher speeds. There will be most deposition when the water is at 1 mph.Therefore, it is clear that deposition will be accumulated the most when water flow is the slowest. Since both Points A and B are the slowest and the same, most deposition would be found there.
