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.
Answer:
Russia is the largest country in the world in land area.
The Ural Mountains lie mainly along the 60° East Longitude Line.
Explanation:
Russia is the largest country in the world in land area, and it is the biggest by far. The country stretches from the Baltic Sea in the west to the Pacific Ocean in the east, and from the Arctic Ocean in the north to the Caucasus and Central Asian steppes. The size of the country has created a lot of good conditions for development (a lot of natural resources) but also some problems (huge distances and inhospitable climate).
The Ural Mountains are a mountain chain in Russia. They are stretching in a roughly north-south direction from the Arctic coastline to the Caspian Sea coastline. This mountain range lies roughly on the 60° East Longitude Line. The Ural Mountains, in their peak, were among the highest mountains in the world, and they are also among the oldest mountains still in existence, but over the course of hundreds of millions of years the erosion has been leveling them and they are now ranging from low to medium height.
