Mountains are important landforms created by different processes in the Earth. Here’s how they form and what makes them special:
Convergent Boundaries: Mountains usually form where two tectonic plates bump into each other. This collision pushes up the Earth's crust. For example, the Himalayas, which include Mount Everest, were created when the Indian Plate hit the Eurasian Plate around 50 million years ago. They are still getting taller by about 4 millimeters each year!
Divergent Boundaries: Here, tectonic plates move apart. This can create rift valleys and sometimes mountain ranges, like the mid-ocean ridges.
Transform Boundaries: These are less common for making mountains. But where plates slide past each other, the rubbing can cause small uplift and create fault-block mountains.
Mountains are special because of their unique features:
Elevation: One of the main ways to identify a mountain is its height. Most mountains rise at least 300 meters (about 1,000 feet) above the land around them.
Relief: Mountains usually have steep slopes and a big difference in height compared to their surroundings. For instance, the Andes mountain range is over 7,000 kilometers long and reaches heights of over 6,960 meters at Aconcagua.
Climate Variation: Mountains have different climates based on their height. Generally, the higher you go, the cooler it gets. This drop in temperature is called the lapse rate, and it averages about 6.5 °C for every kilometer you climb.
Biodiversity: Mountains are home to many different plants and animals. Some species are specially adapted to living there. For example, the Andes has over 30,000 plant species and many species that are found nowhere else.
Mountains affect local weather and play a key role in things like farming, tourism, and mining. Their formation shows how the Earth’s geology works, revealing the power of tectonic movements and erosion over millions of years. Learning about mountains helps us understand geography better and see how all the landforms are connected and influence the Earth’s landscapes.
