Answer:
Europe can be considered as a cultural region.
Explanation:
Europe is part of the Eurasian continent. It has been defined as a separate continent not as all others, but on the basis of culture, religion, and race. While this may come as strange, it is not actually, as almost all ethnic groups are descended from the Aryans, speak Indo-European languages, and follow the same religion (Christianity).
These traits put Europe on the map as a cultural region. Not to be confused though, as these are all general traits, which is in contrast with the high amount of different cultures, languages, and religious fractions throughout Europe. While the continent as a whole can be defined as a cultural region, it has to be mentioned that there are also smaller ethnic groups like the Magyars, Szekely, Finns, Basques, Tartars, etc. that come from different cultural, ethnic, and in some cases religious backgrounds.
The correct answer is - They formed long ago, and erosion has beveled them to their present elevation.
The Appalachian Mountain Range is one of the oldest mountain ranges on the planet. They have formed in the Ordovician Period, around 480 million years ago. When they formed and were at their peak, the Appalachians were much larger and higher than what they are in the present. The reason for their decline in size is attributed to the erosion. The erosion is a process that removes the material from its original position. This process has been influencing, at different rates, the Appalachians for almost half a billion years. Even though the erosion is not a process that acts very quickly, when put the time that it influenced these mountains we will see that it managed to lower them significantly. That process continues in the present, and in the manner in which the continents are moving, there shouldn't be any force that will help lift up the Appalachians again, but instead they will continue to shrink until they are flattened in the distant future.

San Andreas fault is a transform fault- it means that the two plates are not getting closer and converging or getting away from each other and diverging but rather moving in different directions - the American part is moving South and the Pacific part is moving North.
