List and describe at least four reasons why some countries are rich and some are poor. You may use books available at home or you may research online.
Answer:
Reasons why some countries are rich and some are poor include
Difference in productivity rate: Countries with a high productivity rate and who produce a lot of good and services will be rich because a high productivity rate mean a bigger gross domestic product and profit for the country.
Illiteracy/lack of education: Countries who have a stunted educational system will remain poor as education makes it possible for more productivity and access to high paying available jobs which fetches the country income through taxing workers.
Prevalence of diseases: This is a factor that makes a country rich or poor. Prevalence of diseases makes the country focus and spend money meant for other developments in tackling the menace. Investors also avoid places plagued with diseases.This makes the country lose money and become poor.
Low rainfall or drought: This hinders agricultural and conservation activities which helps in providing food and as a tourist attraction respectively. The food which is meant for the citizens and for export purposes is usually small and can’t be exported to gain income for the country which leads to a country becoming poor.

which statement describes divergent boundaries -Divergent boundaries are found only on land -subduction occurs at divergent boundaries -plates move toward each other at divergent boundaries -magma flows from cracks in the crust at divergent boundaries
Magma flows from cracks in the crust at divergent boundaries is the statement describes divergent boundaries. Hence, option D is correct.
What is divergent boundaries?Divergent boundaries happen when, from the centre, plates are moving apart and formed a new crust by magma that pushes up from the mantle. Newly created oceanic crust is just being periodically removed from the ridge crest by two enormous conveyor belts that are facing one another but slowly moving in opposite directions.
When two tectonic plates separate, a deviant border is generated. As magma rises from the Earth's mantle to the surface and solidifies to create new oceanic crust, earthquakes frequently occur along these borders.
Thus, option D is correct.

Explanation:
3 ways by which industries can be financed in west africa
Answer:
Explanation:
There is plenty of ambition in Africa to industrialise, for good reasons. Manufacturing is probably the only proven development model so far that has helped to bring jobs, export revenues and rapid and sustained prosperity to a range of (mainly Asian) poorer countries.
But unless African countries get down to the messy and laborious task of actively promoting manufacturing through targeted infrastructure, skills development, financial policy, making quality connections with agriculture and services in partnership with the private sector, and preparing for a more digital future, significant industrial capacity may never take hold in Africa. The window of opportunity is closing.
Large scale manufacturing on the African continent is mostly absent (automobiles in South Africa being a notable exception). But there are many success stories and promising avenues.
The share of manufacturing in sub-Saharan African gross domestic product (GDP) has declined from 14% in 2000 to 9.6% in 2010 and has remained at that level until now. But it is also true that the value of manufacturing output and exports had doubled over the last decade.
Annual manufacturing growth rates since 2000 were close to 10% in Ethiopia (among the top three in the world), Rwanda and Tanzania – though from a low base. Sub-Saharan Africa’s garment and textiles exports to the United States increased by 18% from the first half of 2017 to the first half of 2018, and a whopping 106% in Ethiopia, thanks in part to a drive to build special economic zones.
There are now major opportunities for African manufacturing. With African markets growing and the new African Continental Free Trade Area signed earlier this year, my colleague Max Mendez-Parra makes the case for increasing regional trade in services which in turn support industrialisation.
There are challenges too. African countries should not expect large scale offshoring of manufacturing jobs from China, as Chinese firms often upgrade domestically and automate in the face of rising wages. It means that African countries need a more targeted approach towards China.
Digitalisation may also affect the ability of African countries to compete as labour costs become less important. Karishma Banga suggests a two-pronged approach: prepare for a digital economy, and build industrial capabilities while you can.
The final three perspectives emphasise that domestic policies and institutions are crucial. While Ethiopia’s experiment with industrial parks is well known and shows the importance of leadership, Tanzania’s experience is full of plans that are not implemented, and recent action is mixed. Kenya lacked coordination but has recently stepped up its action from the centre. Rwanda has recently increased its policy emphasis towards industrialisation – in Rwanda, that normally means ‘we are in business’.
This is exactly what’s needed: African countries must step up at this crucial moment, and seize the opportunity while they still can.
Examine why a system of managed retreat may not be a feasible option in some parts of the coast (6 marks)
Answer:
When a government embarks on an intentional, purposeful, calculated relocation of people and buildings away from risks, this is usually referred to as a Managed retreat.
This is usually carried out due to the presence of hazardous conditions such as the prevalence of wildfire, flood, earthquakes, wildfire, or drought.
Managed retreat strategies are usually accompained by allowing the shoreline to retreat naturally. The disadvantage of this is that land is lost and soon there will be the need for another retreat each time costing the government a lot of resources.
A more feasible option (in some cases) would be to execute "Hard Engineering"
This involves the construction man-made civil structures which try to control natural processes.

trace the history of Meghalaya briefly 80 words minimumly
Answer:
Explanation:
Meghalaya was formed by carving out two districts from the state of Assam: the United Khasi Hills and Jaintia Hills, and the Garo Hills on January 21, 1972. Before attaining full statehood, Meghalaya was given semi-autonomous status in 1970.
The Khasi, Garo, and Jaintia tribes had their own kingdoms until they came under British administration in the 19th century. Later, the British incorporated Meghalaya into Assam in 1835. The region enjoyed semi-independent status by virtue of a treaty relationship with the British Crown.
When Bengal was partitioned on 16 October 1905 by Lord Curzon, Meghalaya became a part of the new province of "Eastern Bengal and Assam." However, when the partition was reversed in 1912, Meghalaya became a part of the province of Assam.
On 3 January 1921 in pursuance of Section 52A of the Government of India Act of 1919, the governor-general-in-council declared the areas now in Meghalaya, other than the Khasi states, as "backward tracts." Subsequently, however, the government of India Act of 1935 regrouped the backward tracts into two categories: "excluded" and "partially excluded" areas.
At the time of Indian independence in 1947, present day Meghalaya constituted two districts of Assam and enjoyed limited autonomy within the state of Assam.
The Assam Reorganisation (Meghalaya) Act of 1969 accorded an autonomous status to the state of Meghalaya. The Act came into effect on 2 April 1970, and an Autonomous State of Meghalaya was created in the state of Assam. The autonomous state had a 37 member legislature in accordance with the Sixth schedule to the Constitution.
In 1971, the Parliament passed the North-Eastern Areas (Reorganization) Act, 1971, which conferred full statehood on the Autonomous State of Meghalaya. Meghalaya attained statehood on 21 January 1972, with a Legislative Assembly of its own
Meghalaya is a state of India located in the country's northeast. It is bounded to the north and northeast by Assam, India, and to the south and southwest by Bangladesh.
What is the significance of Meghalaya?Meghalaya, often known as the Abode of Clouds, is located in northeast India and is home to some of the world's finest biodiversity. This state is known for many things, including its legendary monsoons, rich traditional festivities, and stunning topography.
For the majority of British rule, the tribal territories of the North-East were part of the larger administrative divisions of East Bengal and Assam. Meghalaya did not acquire statehood until 1972, following a powerful but mostly peaceful struggle known as the Hill State Movement.
Meghalaya is known for its rich foliage, rolling hills, and natural beauty. It is also known for its massive orchids.

As to why, despite having an abundance of minerals and natural resources, Pakistan has been unable to realize its potential and has not been able to succeed like other countries having similar resources
Answer:
Well this is due to the presence of a poor and redundant economy and its being unable to purchase latest technological goods and services.
There is also the issue of being unable to reconcile the concerns of Provincial Autonomy and national language. This makes the country lack a sense of direction which has direct and indirect effects on the development of the country.
The country should ensure educational systems in the country are changed and upgraded to the latest in the world so graduates can help the country in more technological findings.
The inability to develop democratic, participative and inclusive institutions is also a factor as foreign investors gets discouraged when their democracy is fragile one.

Answer:
The issue divided Ireland, for a significant unionist minority (largely based in Ulster), opposed Home Rule, fearing that a Catholic-Nationalist parliament in Dublin meant rule by Rome and a degradation of Protestantism.
Explanation:
Ireland–United Kingdom relations, also referred to as Irish–British relations, or Anglo-Irish relations, are the relations between the states of Ireland and the United Kingdom. The three devolved administrations of the United Kingdom, in Scotland, Wales and Northern Ireland, and the three dependencies of the British Crown,[1] the Isle of Man, Jersey and Guernsey, also participate in multilateral bodies created between the two states
Since at least the 1600s, all of these areas have been connected politically, reaching a height in 1801 with the creation of the United Kingdom of Great Britain and Ireland. About five-sixths of the island of Ireland seceded from the United Kingdom in 1921 as the Irish Free State. Historically, relations between the two states have been influenced heavily by issues arising from their shared (and frequently troubled) history, the independence of the Irish Free State and the governance of Northern Ireland. These include the partition of Ireland and the terms of Ireland's secession, its constitutional relationship with and obligations to the UK after independence, and the outbreak of political violence in Northern Ireland. Additionally, the high level of trade between the two states, their proximate geographic location, their common status as islands in the European Union until Britain's departure, common language and close cultural and personal links mean political developments in both states often closely follow each other.
Until Brexit, Irish and British citizens are accorded equivalent reciprocal rights and entitlements (with a small number of minor exceptions) and a Common Travel Area exists between Ireland, United Kingdom, and the Crown Dependencies. The British–Irish Intergovernmental Conference acts as an official forum for co-operation between the Government of Ireland and the Government of the United Kingdom on matters of mutual interest generally, and with respect to Northern Ireland in particular. Two other bodies, the British–Irish Council and the British–Irish Parliamentary Assembly act as a forum for discussion between the executives and assemblies, respectively, of the region, including the devolved regions in the UK and the three Crown dependencies. Co-operation between Northern Ireland and Ireland, including the execution of common policies in certain areas, occurs through the North/South Ministerial Council. In 2014, the UK Prime Minister David Cameron, and the Irish Taoiseach Enda Kenny described the relationship between the two countries as being at 'an all time high.
Home Control was a contentious topic in Ireland since a sizeable unionist minority (mostly in Ulster) opposed it because they believed that a Catholic-Nationalist parliament in Dublin would mean Roman rule and the denigration of Protestantism.
What is Roman Empire?The post-Republican era of ancient Rome was known as the Roman Empire. It was a kingdom with substantial territorial holdings in Europe, North Africa, and Western Asia that was governed by emperors.
Ties between the states of Ireland and the United Kingdom are known as Ireland-United Kingdom relations, Irish-British relations, or Anglo-Irish relations. The Isle of Man, Jersey, and Guernsey, along with the three British Crown dependencies (Scotland, Wales, and Northern Ireland),

PlinianPeleanStrombolianHawaiianWhat causes Plinian eruptions?
Gas exsolution in volatile-rich silicic magmas is what triggers all Plinian eruptions, including the Sub-Plinian, Plinian, and Ultraplinian types. Vesiculation breaks apart as a result of the high viscosity of these magmas. Pyroclasts and expanding bubbles are both erupted at the same time in fast jets that propel eruptions into the stratosphere.
The eruption of the La Garita Caldera in the United States was the most intense one ever recorded. The Earth's temperature was profoundly altered when it happened 2.1 million years ago and created a 35 x 75-kilometer crater. Fortunately, there are only a few of these eruptions per 50,000–100,000 years.
