The Great Plains have the least population of the regions listed above.
Answer:
The geocentric model of the solar system has Earth at the center.
Explanation:
Throughout history, there have been multiple different models that humans thought of or created through observation. The two most famous ones from the past are the geocentric and heliocentric, with the geocentric coming earlier and for a very long time being the model that was accepted by the majority.
The geocentric model is a model that puts Earth in the center of the universe. Earth is presented as the most important and largest object in the universe. All of the space bodies, the Sun, stars, Moon, planets, were thought to revolve around Earth. As it turned out, this model was full of mistakes. Everything about it was wrong, with the only correct thing being that the Moon is actually revolving around Earth.
Answer:
Medullosa would be the least useful index fossil.
Explanation:
When it comes to the past of Earth, what has happened, what was present, why or why not something was there, dating, geology uses numerous different methods. One of those methods, which is relatively accurate and is a good indicator of the layer and other things around it, are the index fossils.
The index fossils are fossils that can be found in numerous different places around the world. They also appear only in a specific and not very long timeline. From the fossils we have presented, while we don't have information about their dispersal, we do have timelines of when the organisms existed. Medullosa is the obvious candidate that would be the least useful if it was to be used as an index fossil. This is due to the enormous timeline of the existence of this organism, stretching somewhere around 90 million years and through two periods, the Carboniferous and Permian, which will make it very hard to find any use of it in determining anything significant.
Yes, because of the hydrologic cycle that continually recycles our water.
Different soil regions influenced human activities because of the fertility of the soil. The more fertile the soil the more agriculture and more agricultural means more food.
