This lava rose and bursted from the Earth's surface, forming the High Cascades chain of volcanoes. Because of the friction and high pressure between the plates, the mantle above the oceanic plate melted, resulting in magma. These mountains were formed by a combination of ocean sediment, basaltic ocean base, continental crust, and mantle from deep within the Earth's crust. The uplift of the Earth's crust produced by the collision of tectonic plates resulted in the development of mountains. ![]() The Cascade Range was produced by subduction when the Juan de Fuca Plate (oceanic crust) sank beneath the North American Plate (continental crust). The southern Cascades, including the High Cascades, on the other hand, was produced as a consequence of volcanic activity. Although there are few significant volcanoes in the northern part, the mountains are not volcanic in nature. The Cascade Range's geology differs between its northern and southern portions. Geology Of Cascade Range Distinctive igneous rock on the side of a volcano on Mount Lassen in California. They are followed to the north by the Coast Mountains of British Columbia and to the south by the Sierra Nevada. The mountains are located 160 to 240 kilometers inland from the Pacific Ocean, east of the large depressions known as the Puget Sound Lowland and the Willamette Valley, which divide the wet coastal region from the drier interior. Helens at 2,550 meters erupted again in 19. Mount Baker 3,286 meters erupted violently in 1975, while Mount St. The majority of the peaks are extinct volcanoes, although Lassen Peak at 3,187 meters and a few others have recently erupted. The islands of Hawaii are actually the summits of an underwater mountain range formed by volcanoes. They are typically created by plate tectonics (such as the Andes in South America) but can also be formed by other processes. Many peaks rise above 3,000 meters, notably Mount Hood at 3,426 meters, Oregon's highest point and Mount Rainier at 4,392 meters, highest in Washington and in the Cascade Range. A mountain range is an area of geologically-related mountains. The Cascades stretch from Lassen Peak in northern California, through Oregon and Washington, to the Fraser River in southern British Columbia, Canada. It has an area of 58,497 sq miles and covers approximately 92% of the US and 8% of Canada. The Cascade Range is a section of western North America's Pacific Mountain chain.
