Why do knick points and waterfalls happen in valley long profiles?
Wiki User
∙ 12y ago
Knick points are an irregularity in the rivers long profile.
Knick points occur in the river when river rejuvenation has taken place, meaning that either the land has risen or sea level has dropped, increasing the gradient of the river at that point. This gives the river greater potential energy and more erosive power. If the knick point is big enough, a waterfall would form.

Knick points and waterfalls form in valley long profiles due to variations in rock hardness or structural changes in the underlying geology. The resistant rock types erode more slowly than surrounding softer rocks, creating sudden drops in the landscape and a steepening of the valley. This process creates a visible boundary in the landscape as the river erodes the softer rock below the knick point.

A valley that has been glaciated by a smaller side glacier and is left standing higher than the main U-shaped valley is a .?
It's called a "hanging valley". Many waterfalls occur at hanging valleys.
What are the most prominent features of a narrow V-shaped valley where the stream profile drops rapidly?
Some prominent features of a narrow V-shaped valley with a stream profile that drops rapidly include steep, rocky walls, minimal vegetation due to the harsh environment, a high-gradient stream flowing through the valley, and the potential for waterfalls and cascades as the stream descends quickly.
When was Jiuzhaigou Valley created?
Jiuzhaigou Valley was created by the geological movement of the Earth's crust around 2-3 million years ago. The valley's distinctive landscape features, including its deep gorges, colorful lakes, and waterfalls, are the result of glacial erosion and tectonic activity over time.
The most prominent features of a narrow V-shaped valley where the stream profile drops rapidly are .?
The most prominent features of a narrow V-shaped valley with a rapidly dropping stream profile are steep valley walls, narrow width of the valley bottom, and a pronounced V shape that indicates erosion by the stream. These valleys often exhibit vertical erosion and can be associated with fast-flowing water and a high energy environment.

When did Valley of the Minotaur happen?
Valley of the Minotaur happened in 1983.
What forms a glacier moves into a stream valley?
A 'V' shaped valley is formed by streams and water action. A 'U' shaped valley is formed by the gouging out of the valley walls by a glacier. A hanging valley is where side valleys are cut across by the main glacier. Hanging valleys often have waterfalls that fall into the main valley over a cliff.

What kind of erosion formed yosemite valley?
Glacial erosion formed Yosemite Valley. Meanwhile, the streams eroded the granite rock to form the waterfalls we know as Yosemite Falls and many others today.
Where did the Valley Forge happen?
Valley Forge was a military camp in Pennsylvania.
Why might yosemite park have so many high waterfalls?
It is due to the fact that the valley is so low compared to the surrounding cliffs. All you have to have is a flowing water source that runs off of the cliff into the valley to have a waterfall that is thousands of feet high. Also, Yosemite has snow melt and rainfall that provides the water for the waterfalls which can be seasonal if there is a bad year of drought.
