Cascade volcanoes theory

Cascade volcanoes are part of the Cascade Range in the Pacific Northwest of the United States, formed by a process called subduction. This occurs when one tectonic plate slides under another, causing melting of the mantle rock and magma formation. As the magma rises, it can erupt, creating volcanoes. The Cascade Range is known for its prominent stratovolcanoes, such as Mount St. Helens and Mount Rainier, characterized by explosive eruptions and layered lava flows. The unique geology and active tectonics of this region contribute to its volcanic activity and the formation of these striking mountains.
