Which planet is small, with a rocky surface and an atmosphere?
A small planet with a rocky surface and atmosphere refers to the inner terrestrial planets like Venus and Mars. Venus has a thick, corrosive atmosphere, while Mars has a thin one. Both have rocky surfaces with geological features.
The planet that is small, with a rocky surface and an atmosphere is one of the inner or terrestrial planets of our solar system, which include Mercury, Venus, Earth, and Mars. Understanding their characteristics helps us compare and contrast them. For example, Mercury is the smallest planet and has a thin atmosphere which causes extreme temperatures. Venus, on the other hand, has a thick corrosive atmosphere and high surface temperatures, with geological features such as mountains and volcanoes that indicate a rocky surface. Earth has a unique atmosphere that supports life, and Mars also has a rocky surface with a thin atmosphere.
Based on the lesson summary provided, all four inner planets are known for their solid, rocky surfaces, but their atmospheres differentiate them. While Mercury's atmosphere is very thin, Venus' is thick and corrosive, Earth's supports life, and Mars' is thin but exists nonetheless. Each planet has unique surface features like craters, mountains, and volcanoes due to their geological histories.
These details not only highlight the differences in the atmospheres and surfaces of these terrestrial planets but also emphasize the factors, such as proximity to the Sun, that determine their conditions and compositions.
Roland writes a story in which boaters become stranded on a sandy island. In the story, they set about collecting materials to create semiconductors to repair computer components in their radio.
Which problem is likely to be the most difficult for Roland’s characters to overcome?
A) There are no semiconductor elements on the island.
B) Any substances they find are too impure.
C) They lack materials to make a p-type semiconductor.
D) No conductors are available to connect the components.
Answer:
C is correct.
Explanation:
If they are on a sandy island there won't be any materials truly pure. Therefore, they will only find impure materials.
The most difficulty for making semiconductors that Ronald's characters have to overcome is that any substances they find are too impure. So, option B is correct.
What is meant by a semiconductor ?A semiconductor is an electrical device whose conductivity range lies in between that of conductors and insulators.
Here,
From the given details above, Roland writes about some boaters who become stranded on a sandy island. In that island, they were set to collect materials to create semiconductors to repair computer components in their radio.
In an island full of sands, the raw materials available for collecting will be extremely contaminated. In order to make good semiconductors they need pure silicon and germanium which are good semiconductor materials. But in the island, the materials will be so impure that there will be a large limitation for collecting raw materials to make semiconductors. There will be no scientific technique in an island to purify the materials, which will be the most difficulty for the boaters.
Hence,
The most difficulty for making semiconductors that Ronald's characters have to overcome is that any substances they find are too impure.
