Study Notes
Carrying Capacity
- Maximum population size of a species that an environment can support based on available resources like food, habitat, and water.
Population Dynamics
- Birth Rate: The number of live births per 1,000 individuals per year in a population.
- Death Rate: The number of deaths per 1,000 individuals per year in a population.
Historical Population Growth
- Human population growth accelerated around 500 years ago due to:
- Introduction of agriculture, enhancing food production.
- Advancement in industry, facilitating better resource management.
- Increased reliability of the world's food supply.
- Improved sanitation, healthcare, and medicine, lowering death rates and raising life expectancy.
- Despite healthcare advancements, birth rates remained high in many areas, leading to exponential population growth.
Geographic Information Systems (GIS)
- GIS: A computer-based program for data storage, management, and analysis.
- GIS maps provide detailed information beyond traditional maps, aiding geographic decision-making.
Information Graphics
- Infographics: Visual representations of data using images or symbols to convey information effectively.
Photography in Geography
- Satellite Photographs: Captured from space, offering a broad perspective for measurements and mapping.
- Aerial Photographs: Taken from the sky, used for measurements and cartography.
Models and Representations of Earth
- Globe: A three-dimensional model of Earth to minimize spatial distortion.
- Atlas: A collection of maps compiled into a book for reference.
- Map: A two-dimensional representation of a specific area of the Earth.
