Mountains are large pieces of land that tower above the land around it. Typically, a mountain comes to a peak and may have a triangular shape. Mountains have higher elevations, so hikers will scale up a mountain by climbing it. When the hiker gets to the top, he or she may experience the weather and air that is at a different altitude.
The tallest mountain is located in the Himalayas. It is almost 30,000 feet from sea level. Mountains are created by natural processes including volcanic eruptions and earthquakes. Sometimes, the heights of mountains are decreased due to erosion. The weather on mountains may be different than the land around it. The higher you climb a mountain, the colder the temperature. Some mountains may also have snow.
