The answer is; Atmospheric circulation patterns keep the temperature of an area constant.
The atmospheric circulation does not keep the temperatures in an area constant, however, they regulate temperatures through convection currents. Hot air rises as cold air mass sinks to replace the rising hot less dense air. These currents transfer energy around the globe and prevent one area from overheating.
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.
D. Stratovolcanoes are the most common types of volcanoes in contrast to the less common shield volcanoes and include Krakatoa and Vesuvius
Explanation:
The statement that does not describe a stratovolcano is the last option.
Cindercone volcanoes are the most common types of volcanoes and are more common than stratovolcano.
A volcano is a landform that originates from magma that cools and solidifies on the surface of the earth.
- Stratovolcano are also called composite volcano.
- They are steep sided volcanoes often with water craters in this middle.
- Some of the lava cools in a stratovolcano before reaching the surface and can lead to violent eruptions.
- They are usually found along destructive margins.
