Mountains are large landforms that rise prominently above their surroundings, typically having steep slopes, a relatively confined summit area, and considerable height. They are formed through a variety of geological processes, and are found on every continent of the world. The study of mountains and mountain ranges is known as orology.
Fold Mountains: Formed when two tectonic plates collide, causing the Earth'scrust to crumple and fold. Examples include the Himalayas and the Andes.
Block Mountains: Formed when faults or cracks in the Earth'scrustforce some blocks of rock to move up and others to move down. Examples include the Sierra Nevada in the United States.
Volcanic Mountains: Formed by the accumulation of lava and volcanic ash. Examples include Mount Fuji in Japan and Mount Kilimanjaro in Tanzania.
Features of Mountains
Mountains are characterized by various features, including:
Summit: The highest point of a mountain.
Slope: The incline or slant of the sides of a mountain.
Ridge: A long, narrow elevation of land that runs along the peak of a mountain or mountain range.
Valley: The low-lying area between mountains, often formed by erosion.
Importance of Mountains
Mountains are of great ecological, cultural, and economic importance. They provide habitats for diverse plant and animalspecies, and are a source of freshwater for rivers and streams. They also offer recreational opportunities such as hiking, skiing, and mountaineering. Additionally, mountains have significant cultural and spiritual value for many societies around the world.
Study Guide
To study mountains effectively, consider the following key points:
Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.
Energy
Students who demonstrate understanding can:
Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.
