Convergent Margin Landforms

Description
-
Convergent margins generally form linear volcanic belts with stratovolcanoes. Stratovolcanoes form due in part to the high viscosity of the magma. On the oceanic side of the convergence, trenches often form from the subduction of the oceanic lithosphere.
The Cascades have large mountains and volcanoes throughout the range. Glass mountain is one of the taller peaks in California; it consists of lava domes and flows.
Medicine Lake Volcano is a more shield shaped volcano. It erupted most recently 950 year ago. The composition ranges from basaltic to rhyolitic
Mount Rainier is found in Washington and is the highest mountain of the cascades. It is a stratovolcano which is still active.
