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

hese structures also modify inland and coastal regions by disrupting the natural flow of sediment.

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.

If a flat lying sedimentary rock layer ends abruptly, which principle tells that it has likely been deformed
Furkat [3]

The principle that tells that the flat lying sedimentary rock layer, which ends abruptly, has likely been deformed is Original horizontality principle. Option D.

<h3>What are the stratigraphic principles?</h3>

  • Superposition principle

Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition.

According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.

  • Lateral continuity principle

When talking about lateral continuity, we refer to different strata -sedimental layers- horizontally deposited that have a limited continuity.

This is, when looking laterally, each layer is not infinite. They tend to smoothly end.

These layers get thinner as they get farther from the source until they disappear.

When looking at plane rocky strata, we can notice they have not suffered from any perturbation and keep the original horizontality.

As they disappear, they tend to

• Mint

• Harrow

• Interdigitate

• be truncated

  • Original horizontality principle

This principle refers to the fact that strata extend originally in all horizontal directions. Sedimental layers are horizontally deposited.

However, it may occur that the currently observed strata arrangement is not the same as it used to be.

This is due to tectonic changes that have modified the original positions. Thus, layers can appear

  • folded,
  • slanted, or
  • inverted⇒ leaving  the most ancient layers in the upper positions.

The principle that tells that the flat lying sedimentary rock layer, which ends abruptly, has likely been deformed is Original horizontality principle. Option D.

Describe the formation, characteristics, and minerals present of the following rocks:
SOVA2 [1]

Explanation:

Serpentine

  • Formation: it forms through serpentinization, a geological low-temperature metamorphic process where low-silica mafic and ultramafic rocks are oxidized and hydrolyzed with water into serpentinite.
  • Characteristics: rich in magnesium and water, light to dark green, greasy-looking and slippery feeling. It can resist the transfer of heat. A source of asbestos, architectural stone, ornamental stone, gem material
  • Minerals present: it follows the formula (X)2-3(Y)2O5(OH)4 where X  can be magnesium, iron, nickel, aluminum, zinc, or manganese; and, Y will be silicon, aluminum, or iron.

Green Schist

  • Formation: they form by regional metamorphism of mafic igneous rocks through depth of burial, and proximity to batholiths.
  • Characteristics: The green is due to abundant green chlorite
  • Minerals present: actinolite and epidote mainly, but they can also include quartz, orthoclase, talc, carbonate minerals, and amphibole.

Basalt Pillow

  • Formation: it forms when lava of basaltic compositions erupted underwater. The rapid cooling of the lava forms the pillow-shaped bodies.
  • Characteristics: they are volcanic igneous rocks, very dark, almost black color.
  • Minerals present: Basalt has a lower percentage of silica and a higher percentage of iron and magnesium than other volcanic rocks.

Umber

  • Formation: it develops in Cyprus massive sulfide deposits.
  • Characteristics: is not one precise color, but a range of different colors, from medium to dark, from yellowish to reddish to grayish depending on the iron oxide and manganese in the clay
  • Minerals present: contains iron oxide and manganese oxide and sulfide precipitates like pyrite.

I hope you find this information useful and interesting! Good luck!
