What is a Mountain?
A mountain is a large natural hill that rises high above the surrounding land. Mountains usually have steep sides and a peak at the top.
How Do Mountains Form?
- Plate T tectonics: The Earth's outer shell is made of big pieces called tectonic plates. When they move, they can crash together and push up rocks to make mountains.
- Volcanic mountains: Some mountains form from eruptions. Lava piles up and creates a tall, cone-shaped mountain.
- Erosion and uplift: Over long times, wind and water wear down rocks, while forces beneath push land upward, creating mountains.
Different Types of Mountains
- Fold mountains: Created when plates collide and bend rocks upward (e.g., the Himalayas).
- Block mountains: Form when large blocks of rock rise between faults.
- Volcanic mountains: Formed by erupted lava piling up (e.g., Mount Fuji).
Fun Facts
- Mount Everest is the highest mountain on Earth above sea level.
- Many mountains are home to unique plants and animals adapted to cold, windy habitats.
- Mountains influence weather by blocking clouds and creating rain shadows.
Why Mountains Matter
They provide water, homes for wildlife, places for adventure, and are important for studying Earth's history.
