- Boreal Forests (Taiga): Coniferous forests found in northern regions.
2. Importance of Forests
- Regulate climate by absorbing carbon dioxide.
- Provide resources like timber, medicine, and food.
G: Glaciers
Glaciers are massive, slow-moving bodies of ice that form over decades from accumulated snowfall. They are crucial indicators of climate change.
1. Types of Glaciers
- Alpine Glaciers: Found in mountainous regions, flow down valleys.
- Continental Glaciers: Cover large areas, such as Greenland and Antarctica.
2. Importance of Glaciers
- Store freshwater and regulate sea levels.
- Impact global ocean circulation patterns.
H: Human Geography
Human geography focuses on the relationship between people and their environments, exploring how culture, economy, and politics shape geographic spaces.
1. Key Areas of Study in Human Geography
- Cultural Geography: Examines cultural practices and their spatial expressions.
- Economic Geography: Studies the distribution of economic activities.
- Political Geography: Analyzes the spatial dynamics of political entities.
2. Importance of Human Geography
- Provides insight into human behavior and societal trends.
- Helps address global challenges like urbanization and migration.
I: Islands
Islands are land masses surrounded by water, varying in size and ecosystems. They play a unique role in biodiversity and culture.
1. Types of Islands
- Continental Islands: Formed from continental landmasses (e.g., Greenland).
- Oceanic Islands: Formed from volcanic activity (e.g., Hawaii).
2. Importance of Islands
- Serve as biodiversity hotspots and unique ecosystems.
- Cultural diversity and heritage sites.
J: Jungles
Jungles refer to dense tropical forests, often characterized by rich biodiversity and complex ecosystems.
