What are the main geographical features of the Earth?.

The Earth's geographical features include mountains, rivers, deserts, and plains, each playing a crucial role in ecosystems and human life.

Key Facts

• Mountains: Cover about 27% of Earth's land surface; the Himalayas are the highest range, reaching over 29,000 feet.
• Rivers: The Amazon River is the longest, spanning approximately 4,345 miles, while rivers support biodiversity and human settlements.
• Deserts: Deserts, like the Sahara, cover about 33% of the Earth's land and are defined by low precipitation (less than 10 inches annually).
• Plains: Make up about 40% of Earth's land area; they are vital for agriculture due to fertile soils.

Examples or Use Cases

• Mountains: Serve as natural barriers and influence climate patterns.
• Rivers: Crucial for transportation and agriculture, e.g., the Nile supports millions.
• Deserts: Host unique flora and fauna, adapted to extreme conditions.
• Plains: Major agricultural hubs, such as the Great Plains in North America.
