Why the Appalachian mountains smooth and rounded?
Erosion after millions of years have caused the jagged edges to smooth out. Hi
What wore down the peaks of the Appalachian Mountains?
Tens of million years of erosion from rain, water movement, wind, freeze/thaw cycles, plant growth.
What are erosional mountains?
from the wvges website Erosional mountains are formed by erosion of uplifts like the Black Hills in western South Dakota and extensive plateaus like the Appalachian Plateau in the eastern United States (which includes western West Virginia). In both of these areas, rivers have carved complex systems of hills and mountains in the uplifted rocks
Were the Appalachian Mountains formed when two continental plates collided?
Yes. Approximately 270-240 million years ago, the continental crusts of ancestral North America and ancestral Africa collided into each other and formed the Appalachian Mountains.
What results from tension between rock layers?
When rock layers bend and buckle it creates mountains. For example, the Rocky Mountains in the west are millions of years younger than the Appalachian Mountains in the east forming from two separate incidents of buckling.

What caused the slow erosion of the Appalachian Mountains?
The Appalachian mountains are a lot older than the Rockies so they are shorter, and rounder. The erosion has been slow over thousands of years, but things that made the mountains erode are running water like streams or rain, wind, and gravity pulling rocks downhill.
What was the tallest mountain range 300 million years ago?
It could have been the Alleghenian or Appalachian Mountain ranges. Based on the amount of sediments from the erosion of the Appalachian Mountains, it is estimated that they were close in height or taller than the Himayan Mountains.
What is the reason why the appalachians are not extremely tall mountains?
The Appalachian Mountains are millions of years older than the Rocky Mountains. Geologists believe the Appalachian Mountains once had active volcanoes because of the types of rocks found but these went extinct long ago. Because of erosion, wind, and time, the Appalachian Mountains are now more rounded and less in height.
What wore down the peaks of the Appalachian Mountains?
Tens of million years of erosion from rain, water movement, wind, freeze/thaw cycles, plant growth.
Are the rocky mountains younger than the Appalachian mountains?
You should know that the Appalachian Mountain is older than the rocky mountain because the Rocky Mountain is 450 years old and the Appalachian Mountain rocks between 100- 200 years old. but the actual Mountain is 200-300 years old
Why are the peaks of the rocky mountains are higher and more jagged than the Appalachian mountains because?
The Appalachian mountains are about 400-500 million years old and have thus been eroded down. The Rocky mountains are very young (they are still being built) and are therefore much higher and jagged as the forces of erosion have not yet had time to grind them away.
Why are the Appalachian Mountains more rounded and shorter than the Rocky Mountains?
because they have been worn down by approximately 250 million years of weathering and erosion. -Star
When were the appalachain mountains formed?
the Appalachian mountains were formed about 165 million years ago
Which mountains are higher the Rocky Mountains or the Appalachian?
The Rockies are higher at 14,440 feet, the Appalachians are 3,000 feet
