Study Notes
Global Mountains
Definition and Formation
- A mountain is a natural elevation of the Earth's surface, usually forming a peak
- Formed through geological processes such as:
- Volcanic activity
- Tectonic plate movement (e.g., folding, faulting)
- Weathering and erosion
Types of Mountains
- Fold Mountains: formed when two tectonic plates collide, causing the Earth's crust to fold (e.g., Himalayas, Rocky Mountains)
- Volcanic Mountains: formed by volcanic activity, resulting in volcanic cones and peaks (e.g., Mount St. Helens, Mount Fuji)
- Block Mountains: formed when a section of the Earth's crust is pushed up or down by tectonic forces (e.g., Sierra Nevada, Appalachian Mountains)
Global Distribution
- Mountains can be found on every continent
- Major mountain ranges include:
- The Himalayas (Asia)
- The Rocky Mountains (North America)
- The Andes (South America)
- The Alps (Europe)
- The Atlas Mountains (Africa)
Importance of Mountains
- Biodiversity Hotspots: mountains support a wide range of ecosystems and species
- Water Sources: mountains are often the origin of major rivers and provide freshwater resources
- Climate Regulation: mountains can influence local and global climate patterns
- Economic Resources: mountains are rich in mineral deposits and provide opportunities for mining, tourism, and agriculture
Challenges and Threats
- Climate Change: rising temperatures and changing precipitation patterns affect mountain ecosystems and human populations
- Deforestation and Land Degradation: human activities such as logging, mining, and agriculture can lead to soil erosion and loss of biodiversity
- Human Settlement and Development: increasing population pressure and infrastructure development can lead to environmental degradation and conflict over resources
