Global Mountain Types
Fold Mountains
- Formed when two tectonic plates collide, causing the Earth's crust to fold and buckle
- Can be thousands of meters thick and hundreds of kilometers wide
- Example: Himalayan mountain range, Rocky Mountains
- Characteristics:
- Folded rocks
- Thrust faults
- Uplifted and eroded terrain
- Often have a central core of ancient rocks surrounded by younger rocks
- Formation processes:
- Continental collision
- Oceanic-continental convergence
- Continental rifting
Volcanic Mountains
- Formed by volcanic activity, such as eruptions and lava flows
- Can be highly variable in shape and size
- Example: Hawaiian Islands, Mount St. Helens
- Characteristics:
- Volcanic rocks, such as basalt and andesite
- Volcanic cones, calderas, and lava flows
- Often have a distinctive conical shape
- Formation processes:
- Magma rising to the surface
- Eruption of lava and ash
- Accumulation of volcanic rocks and deposits
