economic activity and energy

What are the four economic sectors classified by employment?

Primary, secondary, tertiary, and quaternary sectors.

What is the primary sector's focus in economic activity?

The primary sector involves the extraction and harvesting of natural resources, such as agriculture, mining, forestry, and fishing.

What distinguishes the secondary sector in economic activity?

The secondary sector encompasses manufacturing and industrial processes, turning raw materials into finished goods, such as in factories and construction.

What defines the tertiary sector in economic activity?

The tertiary sector includes service industries such as retail, healthcare, education, and entertainment, which provide services instead of goods.

What is the role of the quaternary sector in economic activity?

The quaternary sector involves knowledge-based activities, including information technology, research and development, and financial services, focusing on the production of information rather than goods.

What model explains the differences in employment structures in countries at different levels of development?

The Clark-Fisher Model shows how employment transitions from the primary sector to secondary and tertiary sectors as countries develop.

What factors affect the location of economic activity in the primary sector?

Factors include resource availability, environmental conditions, transportation infrastructure, and market access.

What causes changes in the number of people employed in economic sectors?

Changes are influenced by availability of raw materials, globalization, mechanization, demographic changes, and government policies.

What are the positive impacts of economic sector shifts in a named developed country?

In the UK, sector shifts can lead to increased efficiency, job creation in tech and service industries, and economic diversification.

What are the negative impacts of economic sector shifts in a named developing country?

In India, shifts may cause job losses in agriculture, urban overcrowding, and socio-economic disparities.

What are the causes of informal employment in a megacity?

Causes include economic development, rural-urban migration, and insufficient formal job opportunities.

What are the characteristics of informal employment?

Informal employment is often characterized by low job security, lack of benefits, irregular wages, and limited legal protection.

What are the advantages of informal employment?

Advantages include flexibility, ease of entry into the workforce, and the potential for rapid income generation.

What are the disadvantages of informal employment?

Disadvantages include lack of job security, absence of labor rights, and vulnerability to economic fluctuation.

What theories explain the relationship between population and resources?

Malthus's theory suggests that population growth outpaces resource production, while Boserup's theory argues that innovation can enhance resource availability.

What is the energy gap?

The energy gap refers to the disparity between energy demand and energy supply in a country.

What factors affect global energy demand and production?

Factors include population growth, increased wealth, and technological advancements.

What are some non-renewable energy sources?

Coal, oil, natural gas, uranium, and shale gas/oil.

What are some renewable energy sources?

Solar, wind, hydroelectric power (HEP), geothermal, and biomass.

What are the advantages of renewable energy sources?

Renewable energy sources generally produce lower emissions, are sustainable, and can reduce dependence on fossil fuels.

What are the disadvantages of non-renewable energy sources?

Non-renewable sources contribute to environmental pollution, greenhouse gas emissions, and finite resource depletion.

How can energy be managed sustainably in industries?

Sustainable energy management can be achieved through educating workers, improving energy efficiency, and implementing conservation practices.

What are demographic factors that influence employment shifts?

Demographic factors include age distribution, population growth rates, urbanization trends, and migration patterns.

How does mechanization impact job numbers in the secondary sector?

Mechanization leads to reduced labor demand in secondary industries as machines replace human labor.

What is the significance of energy security for a country?

Energy security ensures a reliable and stable energy supply, mitigating vulnerabilities in energy dependence.

How do technological advancements improve energy production?

Technological advancements improve extraction methods, increase efficiency, and enable the development of alternative energy sources.

What role does government policy play in employment changes across sectors?

Government policies can influence job creation through regulations, subsidies, and incentives that promote or restrict certain industries.

How does globalization affect local labor markets?

Globalization increases competition, encourages outsourcing, and promotes foreign investments that shift local employment patterns.

How does rural-urban migration affect employment in cities?

Rural-urban migration often leads to increased informal employment as migrants seek quick job opportunities in urban areas.

What strategies can be implemented for conserving energy?

Strategies can include promoting energy efficiency, investing in renewable technologies, and enhancing public transport to reduce energy demand.
