Desertification is caused by deforestation, overgrazing, and overworking the soil.
Desertification is an environmental process in which dry, arid areas of land become increasingly uninhabitable and unable to support plant and animal life. This process is caused by a variety of factors, including deforestation, overgrazing, and overworking the soil.
Deforestation is the removal of trees and other vegetation for various purposes, such as to create space for agriculture and urban development. Without trees, the soil is left exposed to the elements and is unable to retain moisture. This leads to the soil becoming dry and barren, creating the perfect conditions for desertification.
Overgrazing is the practice of having too many animals grazing on a given area of land. This can cause the land to become overly depleted of vegetation, which can lead to desertification. Overgrazing can also lead to soil erosion and loss of fertility, as the animals trample and consume the vegetation that would otherwise help retain moisture.
Overworking the soil is the practice of tilling the soil too often or too deeply. This can lead to the depletion of organic matter and soil organisms, which are essential for maintaining soil health. Without the organic matter and soil organisms, the soil is unable to retain moisture, leading to desertification.
All of these practices can have devastating effects on the environment and can lead to desertification. Deforestation, overgrazing, and overworking the soil can all contribute to the depletion of aquifers, salinization, and monoculture. These effects can render entire regions uninhabitable, making it difficult for plants, animals, and humans to survive. Therefore, it is important to take steps to protect our environment and prevent the effects of desertification.

In a constructed development, tell about the crises berlin experienced between 1947 and 1989 to show that it is an example of the cold war.
Answer and Explanation:
After the Second World War, the city of Berlin, Germany, faced several socioeconomic problems that made life very difficult for all citizens. In this scenario, the USA, decided to promote economic aid so that the city could get back up and face its problems. However, at that time the USA was facing a Cold War against the USSR that also had interests in the city of Berlin. This caused the US to dominate one side of Berlin, called West Berlin, while the USSR dominated the other side, called East Berlin. West Berlin received a great economic incentive, it became a democratic city with a capitalist economy, while East Berlin established a communist economy, but it did not have as much economic support and it developed in an inferior way in relation to East Berlin, continuing with several socioeconomic problems. This caused a great political instability to be established in the city, in addition to promoting a great migration of people who left East Berlin to try life in West Berlin, which worsened the economic problems of East Berlin, which was left without labor . In this scenario, the USSR accused the USA of promoting the problems of East Berlin with a strong imperialist campaign, while the USA accused the USSR of causing serious problems to the citizens of Berlin.
This dispute led to the construction of the Berlin Wall, which separated the two sides of the city once and for all and prevented complete communication between the people on each side.
What is the process by which water enters the small pore spaces between particles in soil or rocks?
Soil or rocks infiltration describes the passage of surface water into rock or soil through pore spaces and fissures. Building air leakage is referred to as infiltration (HVAC) in the field of heating, ventilation, and air conditioning.
Infiltration is the spread or buildup of chemicals that are out of the ordinary or in excessive proportions. Tillage breaks up the soil, altering its physical characteristics and hastening surface runoff and soil erosion. Additionally, crop residue is reduced through tillage, which lowers the impact of pelting showers. Long-term tillage.
Degrades organic matter and disrupts soil structure, including pore space and soil aggregation. Without a tillage gap, the soil structure may completely collapse. There is a risk that damaging soil microbial activity could stop it. When soil pores are closed, infiltration is greatly reduced and outflow is increased. Topsoil loss starts to surpass refilling after a few years of continuous tillage due to the passing of The loss of organic matter, nutrients.

The silicate mineral that is found in the greatest variety of igneous rocks of various compositions is Plagioclase.
ABOUT PLAGIOCLASE
Plagioclase is a mineral that belongs to the feldspar group. In Bowen's reaction, plagioclase is in a continuous series. From Bowen's reaction we can also know the process of crystal formation from plagioclase. The plagioclase crystallization process begins with plagioclase-Ca which gradually reacts with the remaining solution until it changes its composition towards plagioclase-Na. This change reaction is called the solid solution series, which means that the crystallization of plagioclase-Ca-plagioclase-Na will continue if it is in an equilibrium state. The chemical formula of plagioclase mineral is NaAlSi3O8-CaAl2Si2O8.
From the Bowens reaction, we can know the process of crystal formation from this plagioclase itself, in which the sequence of crystallization of plagioclase minerals is in a continuous series. The crystallization of plagioclase-Ca in the initial phase was gradual by reacting with the remaining solution, changing its composition from plagioclase-Na. The reaction of this change, plagioclase change is a solit-solution series which is a continuous reaction, meaning that the crystallization of plagioclase-Ca ---- plagioclase-Na (Anorthit ---- Albit ) if in equilibrium will continue continuously.

Hope it Helps!What were farms in the South called?
The term “farm” in the South typically refers to a plantation. A plantation is a large piece of land, usually owned by a single family, where crops are grown to be sold in the market or used to support the family.
Plantations in the South were often very large and could span hundreds of acres of land. During the antebellum period, the majority of plantations in the South were used for growing cotton. Cotton was a very lucrative crop and it was grown in large quantities to be sold on the international market. As a result, plantation owners were often very wealthy and had a great deal of control over their land and the people living on it.
In addition to cotton, many plantations in the South grew other crops such as tobacco, sugar cane, and rice. These crops were also grown in large amounts and sold to the market for a profit. Plantation owners would often employ large numbers of people to work the land and tend to the crops. The workers were typically African-American slaves who were brought to the United States from Africa during the transatlantic slave trade.
In the late 19th century, the majority of plantations in the South were converted to sharecropping. Sharecropping was a system of farming whereby land owners would divide their land into smaller plots and rent them out to tenant farmers. The tenant farmers would then be responsible for growing and harvesting the crops and would return a portion of the proceeds to the land owner as rent.

Which geologic term or phrase explains why the reason rock layers typically form parallel to each other
The geologic term or phrase that explains the reason rock layers typically form parallel to each other called original horizontality.
Nicholas Steno, proposed the concept of original horizontality (1638–1686). According to the Principle of original horizontality, rocks with horizontal strata were initially deposited in a horizontal orientation. These findings support the theory of plate tectonics, which postulates that folded strata are the result of the movement and collisions of huge plates of the Earth's crust, and so prove that the Earth has not been static and that immense forces have been at work over extended periods of time.

In the given parallelogram QRST, x = 7°.
In a quadrilateral, adjacent angles are the pair of angles, that come is formed by the intersection of any common line.
In the question, we are shown a parallelogram QRST and are asked to find the value of x.
We know that ∠TQR and ∠QRS are adjacent, as they include a common side, QR.
∠TQR = 80°, ∠QRS = (14x + 2)°
Now, we know that adjacent angles of a parallelogram are supplementary, that is their sum = 180°
∴ ∠TQR + ∠QRS = 180°
or, 80° + (14x + 2)° = 180°
or, 14x = 180° - 80° -2° = 98°
