Counter urbanisation .is this a suitable option to rural development
Write an essay and discuss the following aspects
Why rural settlements have declined,reasons why dwellers opt for country life ,benefits of living in the economy ,impact on the rural economy .

Answers


Answer: Yes, it appears to be a valid option of the rural development. Explanation: The process of the counter urbanization or de-urbanisation is the demographic ad the social process of the move of the people for the urban to the rural areas. Amongst these impacts are:

Public transport goes into decline. Traditional rural services start to close. Shops and services change to meet the needs of the new population. Traffic congestion increases. rural areas are closely linked, each contributing to the other, which needs to be considered in development planning. Agriculture has a strong impact on urban development. Many fast growing cities are within areas with the most rapid increase in the value of agricultural production. Positives of Counter Urbanisation: Counter Urbanisation can bring benefits to rural areas by bringing new and better transport links and also new services such as petrol stations and shops to that area. it also increases the value of the land as more people are moving out of the city; supporting the local economy. Counter urbanisation is a process in which certain groups of people, often the better off, leave urban areas for rural areas. ... Counter urbanisation generally occurs whn urbanisation reaches a high level. It is a complex process because some people will still be moving to urban areas as others are leaving.
Wealth is generated in cities, making urbanisation a key to economic development. However, urbanisation has caused air and water pollution, land degradation and loss of biodiversity. It has forced millions of people to live in slums without clean water, sanitation and electricity. Counterurbanization, or de-urbanization, is a demographic and social process whereby people move from urban areas to rural areas. It is, like suburbanization, inversely related to urbanization.

What do scientists know about the future of the universe?
A. what dark matter is made of
B. why the expansion of the universe is accelerating
C. that stars will eventually burn out causing the universe to become cold and dark
D. that galaxies spin much slower than they should based on visible matter​

Answers

The correct answer is option C) that stars will eventually burn out causing the universe to become cold and dark.

What happens if all the stars burn out?

Eventually, the cycle of star birth and death will come to an end. Gravity will have won, a victory delayed by the ability of stars to call on the resources of nuclear fusion. But ultimately, gravity will reduce all-stars to a super-dense state as black holes, neutron stars or cold white dwarfs.

What happens when the universe goes cold?

The cosmos will come to a close through a cold and lonely death called the Big Freeze. The region surrounding Sagittarius A, the Milky Way's own supermassive black hole. Eventually, black holes will be the last remaining matter in the universe.

What is formed from nebulae? a. moons b. galaxies c. planets d. stars

Answers

Answer: D. Stars

Explanation: Nebulae are often star-forming regions, such as in the "Pillars of Creation" in the Eagle Nebula.

Stars is formed from nebulae Option(d) is correct. Initially, the expression "nebula" was utilized to depict any diffused cosmic item, including universes past the Smooth Way.

What is a nebulae?

A nebula is an unmistakable radiant piece of interstellar medium, which can comprise of ionized, impartial or sub-atomic hydrogen and furthermore vast residue.

Nebulae are many times star-shaping districts, for example, in the "Mainstays of Creation" in the Falcon Nebula. In these locales, the developments of gas, dust, and different materials "bunch" together to shape denser districts, which draw in additional matter, and ultimately will become thick to the point of framing stars.

The leftover material is then accepted to frame planets and other planetary framework objects. Most nebulae are of tremendous size; some are many light-years in width. A nebula that is apparent to the natural eye from Earth would seem bigger, yet no more splendid, from nearby.

The Orion Nebula, the most brilliant nebula overhead and involving a region two times the precise breadth of the full Moon, can be seen with the unaided eye yet was missed by early space experts.

Therefore Option(d) is correct.

What connection does the author draw between how old offenders are and how they should be treated?

Answers

Answer:

The author draws the connection between how old offenders are and how they should be treated by discussing the scientific research the high court took into account. As stated in paragraph 16, "The high court's rulings also took into account new scientific research, including findings that the areas of the brain that deal with decision making, impulsiveness, and consequences are often not fully developed until people are in their 20s." So, in other words, the author states that juveniles below the age of 20 do not have fully developed brains which can affect the way they behave and their actions. So they should be given a second chance or rehabilitation due to this reason.

Explanation:

What conclusion can be drawn using information from the following graphic that shows principal origins of European immigrants to the United States?

Illustration shows European immigrants drawn to scale of their respective representation by nationality in the United States in 1920. They are shown largest to smallest starting with Germany, which had 1,683,298 residents in the United States in 1920. The smallest figure to the right represents 103,007 Romanian residents. From left to right the countries are Germany, Italy, Russia, Poland, Great Britain, Canada, and Ireland all with a million or more U.S. residents in 1920. After Ireland are Sweden, Austria, Mexico, Hungary, Norway, Denmark, Greece, France, Finland, Holland, Switzerland, Asia, a continent, and Romania.

Immigration of Eastern Europeans was greater than Western European immigration.
Italian and German migrants composed the majority of European-born people in the United States in 1920.
Most French immigrants arrived by way of Canada.
The number of Mexican-born citizens living in the United States was at its highest in 1920.
British and Russian migration to the United States grew at approximately the same rate.

Answers

Answer:

Italian and German migrants composed the majority of European-born people in the United States in 1920.

Explanation:

This is the correct answer because we do not have enough information to support other claims.

First claim is wrong, because most of the countries in here are from Western, not Eastern Europe.

We cannot know from here where did the French immigrants came from.

The same goes for Mexican-born citizens, as we don't have comparative data.

And it also goes for last claim, as we don't have comparison between this two states.

Second option is the only the one that is supported with clear data. Germany had the most immigrants, and Italy is straight behind them on the chart.

Free trade zones
National policies of protectionism
O
Increase in communism
O Decrease in women's rights

Answers

Answer:

The agreements such as NAFTA and WTO reflect a movement toward free trade zones.

Explanation:

The first option is correct because these agreements have the purpose of opening up the borders when it comes to economic collaboration, or in other words, creating free trade zones.

The second option is not correct because the national protectionism is the total opposite of what these agreements are about.

The third option is not correct because communism is based on a command economy, thus a closed and self-sustaining economy.

The fourth option is not correct because these agreements don't have a negative impact on human rights.

Explanation:

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k. k = Graph of f of x and g of x. f of x equals 1 over 3 x minus 3 and g of x equals 1 over 3 x plus 1

Answers

answer:

the value of k is 4.

step-by-step explanation:

given,

f of x equals 1 over 3 x minus 3,

⇒[tex]f(x)=\frac{1}{3} x-3[/tex]

also, g of x equals 1 over 3 x plus 1,

⇒[tex]g(x)=\frac{1}{3} x+1[/tex]

since, g(x) = f(x) + k,

by substituting the values,

⇒ [tex]\frac{1}{3}x+1=\frac{1}{3} x-3+k\\1=k-3\\k=1+3=4\\[/tex]

therefore, the value of k is 4.
