Study Notes
Population
- Population refers to the total number of people living in a particular area.
- Population density is the number of people living per unit of area per square kilometre.
- Population distribution is the pattern of where people live, whether they are spread out evenly or concentrated in certain areas.
- Life expectancy is the expected length of life.
- Population structure refers to the composition of a population, often shown in terms of age and gender.
Age and Population
- Ageing population refers to the number of old people or elderly in a population.
- Young population refers to the number of young people (usually under 15) living in a place.
Birth and Death Rates
- Birth rate is the number of live births per 1,000 people per year.
- Death rate is the number of deaths per 1,000 people per year.
- Natural increase is the difference between the birth rate and the death rate, indicating population growth when births exceed deaths.
Historical Context
- Hunter-gatherers were early humans who lived by hunting animals and gathering plants for food.
- Industrial revolution was a period of time during the late 18th and early 19th centuries that made the world more modern and drastically increased the population.
- Farming began around 10,000 BC when humans settled to more agricultural communities.
Population and Environment
- Sparsely populated areas have a low population density, while densely populated areas have a high population density.
- Population growth refers to the increase in the number of people in an area over time.
- MEDC (More Economically Developed Country) has a high level of economic development and a high standard of living, while LEDC (Less Economically Developed Country) has a lower level of economic development and standard of living.
- Resources are natural materials that are used by humans, such as water, minerals, and forests.
- Sustainable refers to something that can be maintained and will not harm the environment long-term.
Environmental Issues
- Acid rain is polluted rain that harms the environment.
- Global warming is the increase in Earth's average surface temperature due to rising levels of greenhouse gases.
Urbanisation
- Urban area is a city or town with many buildings and people.
- Rural area is a countryside region with few buildings and people.
- Urbanisation is the process of people moving from rural to urban places.
- Slums are overcrowded, poor areas with poor housing and services.
- Push factors are negative aspects, conditions, or wars that cause people to leave a place.
- Pull factors are positive aspects, conditions, or high-paying jobs that cause people to move to a place.
Masdar City
- Masdar City is a planned project in Abu Dhabi, UAE, designed to be a hub for clean technology, eco-friendly resources, and renewable energy.
Coasts
- Coasts are the land next to the ocean or sea.
- Fetch is the distance over water that the wind blows in a single direction, generating waves.
- Waves are the movement of the sea's surface caused by wind.
- Uprush is the movement of water up the beach after a wave breaks.
- Backwash is the movement of water back down the beach toward the sea after a wave has broken.
- Swash is the movement of waves washing up onto the beach.
- Tides are the regular rise and fall of the sea level caused by the gravitational pull of the moon.
- High tide is a tide when the water is at its highest level.
- Low tide is a tide when the water is at its lowest level.
- Tidal range is the difference in height between high tide and low tide.
- Erode refers to the process of wearing away material from the earth's surface by natural forces such as wind or water.
- Deposit refers to the process of adding sediments, soil, and rocks to a landform or land mass.
- Transport refers to the movement of materials from one place to another by water or wind.
- Erode: Attrition is when rocks and pebbles collide and break into smaller pieces.
- Erode: Abrasion is erosion caused by the scraping or wearing away of the earth's surface by materials carried by wind, water, or ice.
- Erode: Hydraulic action is erosion that occurs when water rubs against a rock surface, producing mechanical weathering.
