What economic problem do many Middle Eastern countries experience?

Answers

Answer:

The Middle East and North Africa (MENA) is an economically diverse region that includes countries with a common heritage, at various stages of economic development, and with vastly different endowment of natural resources. Despite undertaking economic reforms in many countries, and having considerable success in avoiding crises and achieving macroeconomic stability, the region's economic performance in the past 30 years has been below its potential. The purpose of this pamphlet is to take stock of the region's relatively weak performance, as measured by rate of growth, links to the global economy, and employment generation; explore the reasons for this outcome; and propose an agenda for urgent reforms.

During a tectonic plate demonstration, a teacher pushes two pieces of clay together. What kind of plate boundary was the teacher demonstrating?
A
convergent
B
earthquake
С
equator
D
divergent

Answers

Answer:

A. convergent

Explanation:

"Tectonic plates" are very important when it comes to studying the Earth. It moves in different directions every year. There are particularly three types of movements or plate boundaries (convergent, divergent and transform).

When the tectonic plates move away from each other, it is called "divergent." When they move towards each other, it is called "convergent," just like what the teacher demonstrated above. Pushing the two pieces of clay together means she's showing the movement of the tectonic plates towards each other. When the plates slide past each other, it is called "transform."

This set of statements applies to which of these?
A) a relic boundary
B) a physical boundary
C) a subsequent boundary
D) a superimposed boundary

Answers

Answer:

D) a superimposed boundary

Explanation:

The set of statements applies to a superimposed boundary. A superimposed boundary does not take into consideration the cultural heritages of people in a particular locality.  

This boundary is cited by powerful and highly influential outside forces. Most national boundaries today have been superimposed. A superimposed boundary often leads to conflict between communities. In some cases, very similar cultures can be split without any consideration for the values of people. Physical boundaries are those the are delineated by geographical barriers. A relic boundary is a non-functional boundary but can still be determined from cultural lines. Subsequent boundaries are those drawn after an area is established. It is dynamic and often changes.
