Detalhes da Resposta
Most less developed nations are trade debtors because of the gross imbalance in international trade. Developed nations typically have strong economies and produce a wide range of goods, while many less developed nations have weaker economies and may be heavily reliant on the export of a small number of commodities, such as raw materials or agricultural products. This can create a situation where the less developed nations have to import a lot of manufactured goods from industrialized nations, but may struggle to export enough to pay for these imports. In addition, the prices of the commodities that less developed nations export can be subject to significant fluctuations on the global market, which can further exacerbate trade imbalances. This can lead to a situation where less developed nations accumulate trade debts, which they may struggle to repay due to factors such as weak currencies and high interest rates. Overall, the trade imbalances between less developed and industrialized nations can be a significant barrier to the economic development of many countries. This is one of the reasons why there have been ongoing debates about the need for more equitable international trade policies and greater support for the economic development of less developed nations.

Detalhes da Resposta
The distribution of settlements in an area is mostly influenced by relief. Relief refers to the physical features of the land, such as hills, valleys, and plateaus, and how they affect the landscape and the availability of resources such as water and fertile land. Settlements tend to form and grow in areas with favorable relief, such as flat or gently sloping land that is well-suited for agriculture and provides access to resources like water and fertile soil. On the other hand, areas with harsh or difficult relief, such as steep mountains or deep valleys, are less likely to attract settlements, as they may not provide the necessary resources for sustainable human habitation.

Pergunta 16 Relatório
the common features of the middle course of a river are?
Detalhes da Resposta
The common features of the middle course of a river are interlocking spurs and meanders. In the middle course of a river, the gradient (slope) of the land is less steep than in the upper course. As the river flows through this area, it begins to meander, or curve back and forth in a zigzag pattern. The river erodes the outside banks of these meanders and deposits sediment on the inside banks, causing the meanders to migrate over time. The eroded material is transported downstream and deposited on the river banks, creating interlocking spurs. U-shaped valleys and flood plains are more commonly found in the lower course of a river where the gradient is very gentle and the river flows slowly towards the sea, depositing large amounts of sediment. V-shaped valleys and rapids, on the other hand, are more common in the upper course of a river where the gradient is steep and the water flows quickly over rocky terrain. Broad interfluves and distributaries are features associated with a delta, which is where a river meets the sea and deposits its sediment in a fan-shaped pattern.
Pergunta 18 Relatório
A form of chemical weathering is?
Detalhes da Resposta
A form of chemical weathering is carbonation. Chemical weathering refers to the process by which rocks and other materials are broken down through chemical reactions. Carbonation is a common form of chemical weathering that occurs when rainwater and other forms of precipitation mix with carbon dioxide in the air to form a weak acid known as carbonic acid. This acid reacts with minerals in rocks, such as calcium carbonate and magnesium carbonate, to dissolve them and create new substances like calcium bicarbonate and magnesium bicarbonate. Over time, this process can cause rocks to erode and break down, leading to the formation of features like caves and sinkholes. Carbonation is an important process in the carbon cycle, as it helps to remove carbon dioxide from the atmosphere and store it in rocks and other materials.

Pergunta 20 Relatório
Which of the following population characteristics is associated with developed countries?
Detalhes da Resposta
Developed countries are typically characterized by a low birth rate and a low death rate. This means that the population growth in these countries is usually slow or even negative. The low birth rate is typically due to factors such as better access to family planning services, a higher proportion of women in the workforce, and a shift towards smaller family sizes. Meanwhile, the low death rate is typically due to factors such as better healthcare, improved sanitation, and higher living standards. Overall, the combination of a low birth rate and a low death rate means that developed countries tend to have aging populations, with a relatively high proportion of elderly people. This can have significant social and economic implications, such as increased healthcare costs and a shrinking workforce. In contrast, developing countries often have a high birth rate and a declining death rate, which can result in rapid population growth. This can create significant challenges in terms of providing adequate healthcare, education, and employment opportunities for a growing population.

The contribution of agriculture to Nigeria's GDP has remained largely low owing to?
Detalhes da Resposta
The contribution of agriculture to Nigeria's Gross Domestic Product (GDP) has remained largely low due to its predominantly subsistence nature. Most of the farmers in Nigeria are small-scale subsistence farmers who produce only enough food to feed their families, with very little left over for sale. This means that the agricultural sector is not producing enough surplus for commercial activities and export, leading to low GDP contribution. In addition, the sector faces other challenges such as inadequate infrastructure, limited access to markets, low productivity, and insufficient access to finance and technology. All these factors contribute to the low contribution of agriculture to Nigeria's GDP.
