Study Notes

Grade 10 Geography: Introduction

The course will primarily focus on the continent of Africa
Students will study Africa's landforms, climate, natural resources, population, economics, and culture.
Human-environment interactions in Africa will be examined.
Geographic issues, public concerns, and geospatial information will be covered.

Grade 10 Geography: Unit One - Landforms of Africa

Learning Outcomes: Students will develop a general understanding of the major landforms globally, identify and describe major landforms in Africa, and recognize their spatial distribution.
1.1 Overview of the World's Major Landforms: Students will learn about the formation of major landforms worldwide, their locations, and variations in distribution.
1.2 Location and Related Features of Africa: Students will study Africa's location relative to other continents and major water bodies.
1.3 Major Landforms of Africa: Students will examine Africa's major landforms, their formation, location, and distribution variations.

Starting Questions

Landforms are physical features on the Earth's surface. Two types exist: major and minor.
Major landforms include mountains, plateaus, and plains. Minor landforms include gorges, river valleys, and basins.
Major landforms form due to tectonic movements and volcanic activities (internal processes).
Minor landforms are primarily formed through erosion from water and wind (external processes).
Continents include:Asia, Africa, North America, South America, Antarctica, Europe, and Oceania (Australia)
A very long period (potentially millions of years) is required for significant landform changes.
The Abay Gorge in Ethiopia took a very long time to form.

Landforms and Water Bodies

Continents are the largest landmasses on Earth. There are seven continents.
Continents cover 29% of the Earth's surface.
Oceans are large bodies of saltwater between continents.
There are five major oceans: Pacific, Atlantic, Indian, Southern, and Arctic.
Oceans cover about 71% of the Earth's surface.
Oceans form a significant factor in shaping coastal landforms (islands, peninsulas, isthmuses, etc.).
An island is a piece of land completely surrounded by water. Greenland is the largest.
A peninsula is a landmass with water on three sides and connected to the mainland on one side. Examples are Italy and Florida.
An isthmus is a narrow strip of land that connects two larger landmasses with water on both sides. The Isthmus of Panama is a well-known example.

Major Types of Landforms

Mountains are the largest and most recognizable landforms, having steep sides and high peaks.
Mountains are formed when rock layers are pushed together, driving the middle portion upwards.
Valleys, the low areas between mountains, can also be formed by volcanic activity.
Mount Everest, in the Himalayas, is the highest landform on Earth (8,849 meters above sea level).
Himalayas were formed around 40 to 50 million years ago due to the collision of the Indian and Eurasian plates.
Landforms can also exist under the oceans, such as mountain ranges and basins (e.g., the Mariana Trench).
Plateaus are large areas of flat-topped, raised land, generated by volcanic activity beneath the Earth's surface.
Plains are vast areas of flat, low-land extending with no hills or mountains. The Great Plains in the mid-United States exemplify large plains.

Importance of Studying Landforms

Understanding landforms is crucial, as they significantly influence human perception and interactions with their environment.
They provide a physical context and influence climate at local (microclimate) and regional (macroclimate) levels.
They are crucial for understanding ecosystems - ecological components develop, and material and energy flows occur within the landform.
Landforms influence economic potentials, the occurrence of disasters, and mechanisms to withstand them or precautions to take.

Africa is bordered by the Mediterranean Sea in the north, the Red Sea in the northeast, the Indian Ocean in the southeast, and the Atlantic Ocean in the west.
Its absolute location spans between -37°21′N and 34°52′S latitudes and -170°33′W and 51°28′E longitudes.
Africa's north-south and east-west extents are roughly 8,000 km and 7,600 km, respectively.
Africa encompasses 30.37 million km², making it the second-largest continent after Asia and covering 6% of the Earth's total surface area.
Africa has approximately 1.3 billion people (2020), making it the second most populous continent after Asia.
Africa is divided into 54 recognized sovereign states.
The equator divides Africa almost equally into two parts, influencing its climate and conditions.

1.3 Major Landforms of Africa

Africa is classified into four major landform regions: the African Alpine System, the African Massif, the East African Highlands and Rift System, and the Southern Africa Platform. Each region contains eight primary physical regions.
These regions vary in size and are differentiated by their unique landforms.

Review Questions

Major landforms of the world: mountains, plateaus, and plains.
Importance of studying landforms: understand human perception, interactions, climate, and ecosystems.
Location of national parks in Africa: The savanna regions are home to many national parks.
Feature dividing Ethiopia: The Great Rift Valley divides Ethiopia into physiographic regions.
