In Senior Secondary School (SSS) Geography, students explore various physical and human geographical topics that form the foundation for advanced study in later years. The second-term syllabus focuses on essential concepts such as the mode of formation of rocks, plateaus, lowlands, and the environment. This guide will provide detailed explanations of each topic, making the content accessible and understandable, especially for novice learners. With clear examples, practical explanations, and evaluations, this article is designed to enhance your understanding of key geographical concepts.
Week 1: Rock/Mode of Formation
Key Concepts:
- Rocks are solid materials that make up the Earth’s crust. They are classified based on their formation process into three main types: igneous, sedimentary, and metamorphic rocks.
Explanation:
- Igneous Rocks: These rocks form from the cooling and solidification of molten magma or lava. Examples include granite (formed from magma) and basalt (formed from lava).
- Sedimentary Rocks: These form from the accumulation and compaction of sediments over time. Common examples are limestone and sandstone, which are created from the compression of mineral particles or organic matter.
- Metamorphic Rocks: These are formed when existing rocks undergo changes due to high pressure, temperature, or chemical reactions. Examples include marble (from limestone) and slate (from shale).
Example:
- Igneous Rock: When magma from a volcano cools slowly beneath the Earth’s surface, it forms large-grained granite.
- Sedimentary Rock: Layers of sand over time compress to form sandstone.
Reading Assignment:
- Study the processes involved in the formation of each type of rock.
Evaluation Questions:
- What are the three main types of rocks?
- How do igneous rocks form?
Week 2: Plateaus
Key Concepts:
- A Plateau is a large, flat area of land that has been uplifted by geological forces.
Explanation:
- Plateaus are typically found at higher elevations than the surrounding land, and they are often characterized by steep slopes and flat tops.
- Plateaus can form through volcanic activity, tectonic movements, or erosion.
Example:
- The Deosai Plateau in Pakistan is an example of a high-altitude plateau formed by tectonic uplift.
Reading Assignment:
- Research the factors that contribute to the formation of plateaus and their significance in the environment.
Evaluation Questions:
- What is a plateau?
- Name one example of a plateau and explain how it was formed.
Week 3: Lowlands (I)
Key Concepts:
- Lowlands refer to areas of land that are lower in elevation compared to their surroundings. These areas are typically located near rivers or along coastlines.
Explanation:
- Lowlands are often rich in fertile soil and support diverse agricultural activities. They can be formed through erosion, sediment deposition by rivers, or subsidence.
- Types of Lowlands: River valleys, coastal plains, and basins.
Example:
- The Niger Delta in Nigeria is a prominent example of a lowland formed by the deposition of sediments from the Niger River.
Reading Assignment:
- Study the characteristics and importance of lowlands in human settlement and agriculture.
Evaluation Questions:
- What are lowlands and how are they formed?
- Mention one example of lowland and its significance.
Week 4: Plains
Key Concepts:
- Plains are vast areas of flat land, usually covered with grass or other vegetation. They are typically formed by the deposition of materials like silt, sand, and clay, often by rivers.
Explanation:
- Plains can be found on every continent and are crucial for farming and human habitation due to their flat terrain and fertile soil.
- Types of Plains: Coastal plains, river plains, and floodplains.
Example:
- The Great Plains in North America are an example of flat areas of land that are ideal for agriculture.
Reading Assignment:
- Research how plains are formed and the role they play in supporting ecosystems and human settlements.
Evaluation Questions:
- What is a plain?
- How do plains contribute to agricultural activities?
Week 5: The Environment
Key Concepts:
- The Environment refers to the surrounding conditions, resources, and influences that affect the life of organisms, including humans.
Explanation:
- The environment consists of both natural (air, water, soil, plants) and human-made (buildings, roads, cities) components.
- Human activities, such as deforestation, pollution, and urbanization, can significantly impact the environment.
Example:
- Deforestation in the Amazon rainforest is an example of human activity that negatively affects the environment.
Reading Assignment:
- Study the components of the environment and how human activities impact it.
Evaluation Questions:
- What is the environment?
- How do human activities affect the environment?
Week 6: Weather and Climate (I)
Key Concepts:
- Weather refers to the atmospheric conditions in a specific location over a short period, while climate refers to the average weather conditions over a longer period (typically 30 years or more).
Explanation:
- Weather includes factors like temperature, humidity, wind, and precipitation, and it changes daily.
- Climate is the long-term pattern of weather in a region and is classified into different types like tropical, temperate, arid, etc.
Example:
- Weather: A hot sunny day in Lagos.
- Climate: The tropical climate of Nigeria, characterized by high temperatures and seasonal rainfall.
Reading Assignment:
- Learn about the factors that influence weather and climate.
Evaluation Questions:
- What is the difference between weather and climate?
- Name two types of climates and describe their characteristics.
Week 7: Weather and Climate (II)
Key Concepts:
- Factors Affecting Climate: Latitude, altitude, distance from the sea, ocean currents, and winds all influence the climate of a region.
Explanation:
- Latitude: Areas near the equator receive more direct sunlight and are typically hotter.
- Altitude: Higher altitudes tend to have cooler climates.
- Distance from the Sea: Coastal areas have more moderate climates compared to inland areas.
Example:
- Coastal regions like Lagos experience a more moderate climate compared to inland areas such as Kano.
Reading Assignment:
- Investigate how each factor affects climate patterns in various regions.
Evaluation Questions:
- What factors influence the climate of a region?
- How does latitude affect the temperature of a place?
Week 8: Map Work
Key Concepts:
- Map Work refers to the skills involved in reading, interpreting, and using maps to understand geographical information.
Explanation:
- Maps represent the Earth’s surface and include features such as rivers, mountains, roads, and cities.
- Types of Maps: Physical maps, political maps, topographic maps, and thematic maps.
Example:
- A physical map of Africa would show mountains, rivers, and deserts, while a political map would show countries and borders.
Reading Assignment:
- Study different types of maps and how to use them for geographical analysis.
Evaluation Questions:
- What is map work and why is it important in Geography?
- Identify the differences between a physical map and a political map.
