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.

The difference between craters and calderas is in the formation mode of each of them. Craters generally are more circular and smaller, and result from the projection of gas and magma, while calderas arise from falling stones and rocks.</span>
Answer:
is caused by earth's rotation
Explanation:
- The Coriolis effect is the direct result of the earth's constant motion around its axis and in which he objects are deflected towards the right in the northern hemisphere and to left in the southern hemisphere. It is also called as an initial or fictitious force with reference to clockwise rotation.
