What is the difference between erosion and deposition?

1 answer:

3 0

Erosion is the displacement of solids (soil, mud, rock and other particles) by the agents of wind, water or ice, by downward or down-slope movement in response to gravity or by living organisms (in the case of bioerosion).

Deposition, also known as sedimentation, is the geological process whereby material is added to a landform. This is the process by which wind, water or ice create a sediment deposit, through the laying down of granular material that has been eroded and transported from another geographical location.

Deposition occurs when the forces responsible for sediment transportation are no longer sufficient to overcome the forces of particle weight and friction, which resist motion. Deposition can also refer to the build up of a sediment from organically derived matter or chemical processes. For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton, the deposition of which has induced chemical processes (diagenesis) to deposit further calcium carbonate.

How can the size and charge of ions influence the chemical variation of mineral compositions

andrey2020 [161]

Answer:

As rocks on the earth go through various cycles, similarly the variation in chemical take place.

Explanation:

As there exists a difference in the composition of minerals chemical composition from there pure forms, some variation exists in the chemical composition of elements like the size of irons, ad the temperatures at which the crystal grows.

As rocks are an aggregate of more than one mineral they have distinct qualities like the granite is defined by the by proportions of quartz, and feldspar. Like the coal is a sedimentary rock being composed of carbon.

The presence of oxygen, silicon, magnesium, calcium, and sodium in rocks defines their constituents, as by far Oxygen and Silicon is two of the most dominant 47% and 28%.

An example of chemical alteration on earth is the volcanic rocks that are both igneous and metamorphic Depending on the chemical properties of these rocks the various metallic nature of elements the rocks have different temperatures and magnitudes.

A circle has a diameter

torisob [31]

The circumference of circle is 20.096 units

Solution:

Given that circle has a diameter with endpoints at (10, 8) and (5, 4)

To get the diameter, find the distance between the end points

The distance between two points is given by formula;

$d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

Here the points are (10, 8) and (5, 4)

$(x_1, y_1) = (10, 8)\\\\(x_2, y_2) = (5, 4)$

Substituting the values we get,

$\begin{aligned}&d=\sqrt{(5-10)^{2}+(4-8)^{2}}\\\\&d=\sqrt{(-5)^{2}+(-4)^{2}}=\sqrt{25+16}=\sqrt{41}\end{aligned}$

$d = \sqrt{41} = 6.4$

Thus the diameter is 6.4 units

The circumference of the circle is given by formula:

$c = \pi d$

Where "d" is the diameter of circle

$c = 3.14 \times 6.4 = 20.096$

Thus circumference of circle is 20.096 units

En Uganda el 16% de la población es urbana y el 84% rural ¿que inplicaciones de relevancia social tiene esto?

Serggg [28]

Answer:

El país depende de la agricultura.

Explicación:

En Uganda, el 16% de la población es urbana y el 84% rural, las implicaciones sociales de esta proporción de poblaciones son malas para la economía porque más personas viven en las aldeas relacionadas con la agricultura y menos personas viven en las ciudades significa que menos personas trabaja en las industrias y oficinas. Debido a que hay menos gente en las zonas urbanas y más en las zonas rurales, el país todavía depende de la agricultura en comparación con las industrias, lo que conduce a una mala situación económica del país.
