Humans have built artificial levees along the Mississippi River to protect themselves and their property from floods. However, t

The correct answer is - A. reduce the amount of sediment deposited on floodplains and increase the amount of sediment deposited at the river's mouth.

The Mississippi River is one of the biggest rivers in the world. It is also a river that carries with it very large amount of sediments. The levees built along side it though do not allow the natural process of deposition of sediments on the floodplains of the river. That results in the river carrying the sediments down to the river mouth. Because of this, the river mouth is becoming an ever-growing delta because of the constant deposition of very large amounts of sediments. This also causes lot of the sediments to end in the coastal parts of the sea, which makes the sea waters shallower and murkier, as well as creating new land forms alongside the coast from the deposited material.

Which describes the boundary where earthquake activity occurs along rift valleys?
Andreyy89

Answer:

divergent boundary on land

Explanation:

Divergent boundary involves the crustal spreading of two tectonic plates. Divergent boundary is the separation or rifting apart of two plates. Divergent boundary can occur between oceanic plates or continental plates.

Divergent boundary between oceanic plates , the convection currents lift the lithosphere producing a mid oceanic ridge. Extensional forces spreads the lithospheric plate apart causing an in flow of magma from the interior of the earth. The magmatic materials travels through fissure and oceanic ridges to the surface of the ocean floor. The volcanic material/magma later solidifies to form new oceanic crust with the youngest rock closest to the mid oceanic ridge.

Divergent boundary between continental plates , the convection current usually pull the continental plates upward due to the thickness of the continental plates. The continental plates are pulled thin by the extensional forces resulting to fracture. The fracture result into a rift shaped structure. Rift valleys are formed which is a lowland region. The two parts of the continents(lands) that are separated are likely to develop fault on both sides of the rifts. The fractured area along the rift valley is a region prone to earthquakes.

Rift valley are structures found in divergent boundary between continents(land) and are region of earthquakes activities because of movements and fracturing occurrence. The East African rift is an example of this kind of plates boundary.

What are pros of living near a canyon
babunello [35]

Answer with Explanation:

A canyon is a natural area where both living and non-living organisms are found. Residing near it brings several benefits. <u>One of these is having the opportunity to exercise.</u> A person may access the canyon for his daily jog or walk. He may also do a little bit of hiking.<u> Another benefit is having good quality of water (free from pollutants).</u> The vegetation in the canyon prevents the urban runoff (usually from storms) from polluting the bodies of water.<u> Lastly, it gives the person a chance to see wildlife.</u> Many of the canyons are being preserved; thus, it's an opportunity to see many endangered habitats in it.
