The Appalachian Mountains are an example of a folded mountain range. Based on this information, which of the following processes
formed the Appalachians? Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.
Tectonic movement forced certain segments of Earth's crust downward and other segments upward in jagged chunks.
One tectonic plate moved beneath another plate at a subduction zone, causing the rock to melt and rise above Earth's surface.
Segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes.
The answer is that segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes.
One key to finding the answer is that fold mountain range is caused by the collision of plate at destructive plate boundary, causing the land to fold up under pressure from both sides.
Let's look into the choices one by one:
Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled. - While volcanism is one of the features formed by collision,it cannot be applied in this case as there is no sign of volcanism.
Tectonic movement forced certain segments of Earth's crust downward and other segments upward in jagged chunks. - By no means would the crust move downwards under collision,thus this is not true.
One tectonic plate moved beneath another plate at a subduction zone, causing the rock to melt and rise above Earth's surface. -While molten rock subducted do produce magma,the mountain chain is not formed by volcanism, thus the statement cannot be applied.
Segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes.- The statement is correct as explained above. Differential weathering is also one of the reason why the mountain comes in chain.
