The Grand Tetons over the next 9 million years A. The Grand Tetons will become less steep and more rounded. Therefore , A. The Grand Tetons will become less steep and more rounded is correct .
The Grand Tetons are made up of very hard rock, which is resistant to weathering and erosion.
However, over millions of years, even the hardest rock will eventually wear down.
Here are some of the ways that weathering and erosion will affect the Grand Tetons over the next 9 million years:
Weathering will break down the rock at the surface of the mountains. This will create small cracks and crevices, which will make it easier for water and ice to get into the rock and break it down further.
Erosion will carry away the broken rock debris.
This will happen through a variety of processes, such as wind, water, and ice.
Over time, the mountains will become less steep and more rounded. This is because weathering and erosion will wear down the sharp peaks and ridges of the mountains.
The valleys between the mountains will also become wider and deeper.
This is because the eroded rock debris will be deposited in the valleys.
While the Grand Tetons will be significantly impacted by weathering and erosion over millions of years, they will still be recognizable as the same mountain range.
Here are some of the changes we can expect to see:
The peaks of the mountains will become less sharp and more rounded.
The valleys between the mountains will become wider and deeper.
Talus slopes will continue to form at the base of the mountains.
The overall height of the mountains will decrease slightly.
Despite these changes, the Grand Tetons will still be a majestic and awe-inspiring sight.
