Some examples of fault-block mountains include the Sierra Nevada and the Grand Tetons in the United States and the Harz Mountains in Germany. Fault-block mountains are formed as a result of cracking or faulting along the planet's surface, leading to several crustal blocks being heaved upwards while other chunks of rocks slide downwards.Know More
Mountains are geographical landforms that originate from the natural deformation of the Earth's crust, which is brought on by the gradual movement of continental plates through the process of orogenesis. The major forces that drive orogenesis are faulting, structural deformation, folding, metamorphism, igneous processes, erosion, glaciation and sedimentation.
Mountains are primarily classified into five main categories, including fault-block mountains, fold mountains, dome mountains, volcanic mountains and plateau mountains. Fault-block mountains, also referred to as block mountains, are created when an irreversible strain occurs within or between crustal plates, which eventually causes faulting or fracturing of the Earth's surface. The fractured section pulls apart and fragments into large pieces of rock. These crustal blocks either move up or move down. The rocks that slide down are called "grabens." The blocks that are uplifted and end up being piled one on top of the others are called "horsts," which serve as the foundation for fault-block mountains. Other mountains located in the Basin and Range province in the U.S. are further examples of fault-block mountains.Learn more about Landforms
According to About.com, the Earth creates mountains through plate tectonics, where its crust is broken into plates constantly in motion, causing stress and uplifting in order to grow mountains. While growth is slow due to these forces, it does happen.Full Answer >
A group of mountains is known as a mountain range. A group of ranges that share a common origin and form are a mountain system. A group of systems are a mountain chain. A group of ranges, systems and chains are known as a mountain belt or a cordillera.Full Answer >
Volcanic mountains form as lava oozes forth from cracks in the earth. The lava builds up around the area where the eruption occurred. Layers build upon layers and over a period of time, a volcanic mountain forms.Full Answer >
The Cascade Mountains were formed as a chain of volcanoes, a manifestation of the Pacific Ring of Fire in the Pacific Northwest. The Ring of Fire is caused by the oceanic plates offshore subducting beneath the North American Plate. This destabilizes the hot mantle rocks below, liquefying them and forcing them upward, producing increases in elevation and even volcanic craters where magma pushed its way through.Full Answer >
