SS 2 Geography Lesson Notes for Second Term

This SS 3 Geography curriculum is designed to give students a solid understanding of the major geographical themes affecting our world today. The focus is on key concepts that not only prepare students for exams but also empower them to comprehend global challenges and opportunities. By the end of the term, students will be able to understand complex geographical topics and apply their knowledge to real-world issues. Each lesson note is structured to be clear, engaging, and easy to understand for students of all levels, even if they are new to the subject.

Week 1: World Population (I)

In this lesson, we will explore the concept of population geography, which examines the distribution, composition, and growth of the world’s population. Understanding population dynamics is essential as it directly influences global development, urbanization, and resource allocation.

Key Concepts

  1. Population Density:
    • Definition: Population density refers to the number of people living per unit of area, typically measured in people per square kilometer.
    • High-density areas: Cities or regions with favorable climates and resources, such as Lagos, New York, and Tokyo, often experience higher population densities.
    • Low-density areas: Regions like deserts (e.g., the Sahara) or frozen tundras (e.g., parts of Canada and Russia) are sparsely populated.
  2. Population Distribution:
    • Definition: Population distribution refers to the spatial arrangement of people across the planet.
    • Populations are usually concentrated in areas with easier access to resources, such as fertile lands, water bodies, and temperate climates. For example, China and India have very high population densities due to their fertile lands, ideal climate, and agricultural development.

Factors Influencing Population Distribution

  1. Physical Factors:
    • Climate: Regions with temperate climates (moderate temperatures and rainfall) tend to have higher population densities, while extreme climates like deserts or icy regions see lower population densities.
    • Topography: Flat or gently sloping land is more favorable for settlement and farming, while mountainous areas can pose challenges for habitation and agriculture.
    • Water Bodies: Proximity to rivers, lakes, and oceans plays a key role in human settlement, as these areas offer transportation, water, and fertile soil for farming.
  2. Human Factors:
    • Economic Opportunities: Areas with industries, employment, and resources attract more people.
    • Politics: Political stability and government policies influence migration patterns, such as refugee movements or incentives for settlement in certain regions.
    • Social Factors: Cultural, religious, and historical reasons can also shape where people live, such as migration trends based on community needs or access to social services.

Example:

Countries like China and India have some of the highest population densities in the world, primarily due to their fertile land, favorable climate, and large-scale agriculture. These factors support a high concentration of people who are involved in farming and other industries.

Reading Assignment:

Research how population density affects urban development and resource distribution in major cities such as Lagos, New York, and Tokyo. Focus on understanding how the high density of people in these cities impacts housing, transportation, and public services.

Evaluation Questions:

  1. Define population density and explain how it is calculated.
    • Population density is the number of people living in a given area (usually per square kilometer). It is calculated by dividing the total population of an area by its total land area.
  2. List the factors that affect the distribution of population in the world.
    • Physical factors: Climate, topography, water bodies
    • Human factors: Economic opportunities, politics, social factors
  3. Explain why population density is higher in coastal regions compared to mountainous areas.
