How does River erosion affect landscapes in the mountain

Geography
1 answer:
ki77a [65]3 years ago
5 0

Answer:

Explanation:

Rivers have three sections or courses: the upper course, middle course and lower course. The upper course of a river typically sees much erosion of bedrock in order to achieve the equilibrium mentioned above.

The upper course is also at the highest altitude as this is where the headwaters of the river originate. Rivers in the upper course erode down vertically which often creates a steep channel profile in what becomes the river valley.

The middle course sees a river at a slightly lower altitude than the upper course, but is still maintains a sense of trying to acquire equilibrium in flow and shape. The discharge and velocity of the river still allows the water to erode the banks and chart a course of least resistance through lateral erosion.

The lower course is unique as this is the stage in which a river has reached sea level. Here we find features not found in the middle and upper courses like floodplains and river deltas that have been formed by the sediment deposits of rocks and dirt gathered from upstream.

<h2>The following are the events in a story of how people have interacted with a landscape put into chronological order: </h2><h2> </h2>

1. Dense forest with large trees on steep hills: There were steep hills covered by forests made by large trees. The roots of these trees ceased soil erosion from happening.

2. Hand logging near lakes: People began to cut trees for wood but the pace was not as fact.

3. Mechanized logging throughout hills: Techniques of mechanized logging were developed and which helped in clearing the trees from over the hills within months.

4. Erosion fills lakes with silt: Clearing of forests from over the hills caused soil erosion and the silt from the hills flowed down with rainwater runoff.

In recent years, the war on drugs has centered on the border between Mexico and the United States. Which of the following statem
maxonik [38]

Answer: A. The amount of violence has been decreasing, so few people have been killed.

Explanation:

The "War on Drugs" does indeed see the U.S. government spending more than $500 million a year as they raid supply chains and arrest traffickers to stem the flow of drugs into the U.S.

Most of the violence does occur near the U.S.-Mexico border as gangs fight to control smuggling routes and U.S. agents attempt to stop them along with police officer, most of whom are dedicated to ending drug smuggling.

The violence however has not been decreasing. Indeed, cartels have become more violent and with the rise of new cartels like the New Jalisco cartel, the violence has spread.

The convergent plate boundaries are formed when two lithospheric plates move toward each other. The nature of a convergent bound
oee [108]

Answer:

1. oceanic-oceanic boundaries

2. oceanic-continental boundaries

3. continental-continental boundaries

Explanation:

The three types of plate convergence are:

1. oceanic-oceanic boundaries: this occurs when two oceanic plates clash; thereby the heavier plate forms below the lighter plate resulting in dark, heavy, basaltic volcanic islands.

2. oceanic-continental boundaries: this occurs when there is a collision between oceanic and continental plates, resulting in the downward movement of oceanic plate, while the volcanic arc rises on land

3. continental-continental boundaries: this occurs due to the massive crust of slabs clashing against each other. Thereby leading to big mountains forming from folded, faulted, and thickened convergent boundaries
