UNIT 1: MAJOR FEATURES OF THE EARTH

The Earth is made up of several natural features that support life and influence human activities. Understanding these features helps teachers explain how people interact with their environment.

1. Atmosphere

The atmosphere is the layer of gases that surrounds the Earth. It is held in place by gravity and plays a very important role in sustaining life.

The atmosphere:

• Contains oxygen needed by humans and animals for breathing.

• Protects the Earth from harmful rays of the sun.

• Helps to regulate temperature and climate.

• Is responsible for weather elements such as rainfall, wind, clouds, and humidity.

Without the atmosphere, life on Earth would not be possible.

2. Lithosphere

The lithosphere is the solid outer layer of the Earth. It includes the land surface, rocks, soil, mountains, and valleys.

The lithosphere:

• Supports human settlement and farming.

• Provides natural resources such as minerals, rocks, and soil.

• Is where activities like mining, construction, and agriculture take place.

Examples of lithospheric features include mountains, plains, plateaus, and valleys.

---

3. Vegetation

Vegetation refers to the plant cover found on the Earth’s surface. It includes trees, grasses, shrubs, and forests.

Vegetation:

• Provides food and shelter for humans and animals.

• Helps to prevent soil erosion.

• Improves air quality by absorbing carbon dioxide and releasing oxygen.

• Supports economic activities such as farming and logging.

Different areas have different types of vegetation depending on climate and soil conditions.

---

4. Highlands and Lowlands

Highlands are areas of high elevation above sea level, such as hills, mountains, and plateaus.

Lowlands are areas of low elevation, usually flat or gently sloping lands.

Importance:

• Highlands influence climate and rainfall patterns.

• Lowlands are suitable for farming, settlement, and transportation.

---

5. Water Bodies

Water bodies are large collections of water found on the Earth’s surface. They include rivers, lakes, seas, oceans, and lagoons.

Water bodies:

• Provide water for drinking, irrigation, and industries.

• Support fishing and transportation.

• Influence climate and weather conditions.

UNIT 2: WATER BODIES IN GHANA

Ghana is endowed with several rivers and lakes that are important for economic and social development.

Major Rivers in Ghana

River Densu

• Flows through the Eastern and Greater Accra Regions.

• Supplies water to Accra and surrounding communities.

River Ankobra

• Located in the Western Region.

• Supports mining and farming activities.

Black Volta and White Volta

• Found in the northern part of Ghana.

• They join to form the Volta River.

• Used for irrigation and fishing.

River Tano

• Flows along the western boundary of Ghana.

• Important for farming and domestic use.

River Bia

• Located in the Western North Region.

• Supports agriculture and human settlement.

River Offin

• A tributary of River Pra.

• Flows through forest zones and supports farming.

---

Volta Lake

The Volta Lake is the largest artificial lake in Ghana and one of the largest in the world.

Importance of Volta Lake:

• Generates hydroelectric power at Akosombo.

• Supports fishing and transportation.

• Provides water for domestic and industrial use.

---

Importance of Rivers and Lakes in Ghana

• Source of water for drinking and irrigation.

• Support fishing activities.

• Aid transportation and trade.

• Generate electricity.

• Support tourism.

---

UNIT 3: VEGETATION ZONES OF GHANA

Vegetation zones refer to areas with similar plant cover due to similar climatic conditions.

1. Tropical Rain Forest

• Found in the southwestern part of Ghana.

• Has tall trees and heavy rainfall.

• Supports cocoa and timber production.

2. Semi-Deciduous Forest

• Located in the middle belt of Ghana.

• Trees shed leaves during dry seasons.

• Supports food crop farming.

3. Savannah

• Found in northern Ghana.

• Characterized by grasses and scattered trees.

• Supports livestock rearing and crop farming.

4. Coastal Scrub and Grassland

• Found along the coast of Ghana.

• Has short grasses and shrubs.

• Suitable for fishing and salt mining.

5. Strand and Mangrove

• Found along lagoons and river mouths.

• Supports fishing and protects the coastline.

UNIT 4: CONTINENTS OF THE WORLD

A continent is a large continuous landmass on the Earth’s surface.

The seven continents are:

Africa

• The second-largest continent.

• Ghana is located in West Africa.

Asia

• The largest continent.

• Contains countries like China and India.

Europe

• Known for early industrial development.

North America

• Includes countries like USA and Canada.

South America

• Known for the Amazon Rainforest.

Oceania

• Includes Australia and Pacific islands.

Antarctica

• Covered with ice.

• No permanent human settlement.

UNIT 5: BASIC MAP SKILLS

Map skills help individuals understand and interpret geographical information.

Using Maps to Locate Physical Features

Maps help us locate:

• Rivers

• Mountains

• Cities

• Countries

---

Direction (Cardinal Points)

The four main cardinal points are:

• North

• South

• East

• West

They help in describing location and movement.

---

Symbols and Legends

Symbols are signs used to represent features on a map.

A legend (or key) explains the meaning of symbols used on a map.

Importance:

• Makes maps easy to understand.

• Helps users interpret information correctly.
