Answer:
What happens when an impactor hits?
When an impactor strikes the solid surface of a planet, a shock wave spreads out from the site of the impact. The shock wave fractures the rock and excavates a large cavity (much larger than the impactor). The impact sprays material — ejecta — out in all directions. The impactor is shattered into small pieces and may melt or vaporize. Sometimes the force of the impact is great enough to melt some of the local rock. If an impactor is large enough, some of the material pushed toward the edges of the crater will slump back toward the center and the rock beneath the crater will rebound, or push back up, creating a central peak in the crater. The edges of these larger craters also may slump, creating terraces that step down into the crater.
What are the major parts of a crater?
Floor – The bottom of a crater, either bowl-shaped or flat, usually below the level of the surrounding ground.
Central peaks – Peaks formed in the central area of the floor of a large crater. For larger craters (typically a few tens of kilometers in diameter) the excavated crater becomes so great that it collapses on itself. Collapse of the material back into the crater pushes up the mound that forms the central peak. At the same time, the rock beneath the crater rebounds, or bounces back up to add to the peak.
Walls – The interior sides of a crater, usually steep. They may have giant stair-like terraces that are created by slumping of the walls due to gravity.
Rim – The edge of the crater. It is elevated above the surrounding terrain because it is composed of material pushed up at the edge during excavation.
Ejecta – Rock material thrown out of the crater area during an impact event. It is distributed outward from the crater's rim onto the planet's surface as debris. It can be loose materials or a blanket of debris surrounding the crater, thinning at the outermost regions.
Rays – Bright streaks extending away from the crater sometimes for great distances, composed of ejecta material.

as closely as independent news sources<span>
<span>It is
important to specify the sources that these mainstream and independent news
receive. Sources are very sensitive to bias and prejudice hence, reliable,
credible and valid sources are consistent and clear throughout any media,
without any disparities. </span></span>
Answer:
by using exclamation points
Explanation:
Formal writings are writing styles adopted for use in professional, academic and other setting which does not involve a personal level of interaction. Therefore, formal writing setup are more organized and guided than informal writings. In formal writeups, there may also be need to show emotions such as excitement, happiness, surprise a d so on. If it were in an in formal setting the use of emoticons would be a very good way to show emotions due to the various emoticon labels available. However, the use of an exclamation mark (!) may be adopted in formal writing to express emotions. In many texts, the use of one (!) rather than three (!!!) is more appropriate for formal writings.
The phrase from the excerpt that best indicates that the purpose of the essay is to inform is “I know this for a fact”. This phrase helps the author introduce evidence to the text that supports her ideas.
In this case the author tells a personal experience as a way to provide more information and the context of her essay.
The rest of the options are incorrect as they are part of the personal experience that the author is narrating.
This question refers to the novel <em>Frankenstein</em> by Mary Shelley. In this book, we learn of a monster or a creature that is created by a scientist. After the creature escapes, he wants to learn more about humans and the world, and he does so by reading <em>Paradise Lost</em>, which tells the story of Adam and Eve.
It is dangerous for the creature to read <em>Paradise Lost</em> as a true story because this is not the purpose of such a text. <em>Paradise Lost </em>is a story that is meant to be allegorical and symbolic. This can also be said of other religious texts, as they do not convey the reality of the world objectively. Therefore, the creature would not benefit much from reading them. As for fictional works, the creature would encounter a similar problem, as these stories do not necessarily tell facts. The creature, however, could benefit from reading books on history, biology, philosophy or other similar subjects, as these are more likely to give an accurate image of the human world.
