The Cascade chain of volcanoes formed much like many other volcano chains, which is to say that it formed over a convergent plate boundary, where two tectonic plates met. Specifically, an ocean plate, (higher density than land plates,) was forced under a land plate, which caused the plate to melt, once within the earth's mantle. It became less dense, as molten material is less dense than solids, just like liquides are less dense than solids. Because the molten earth was less dense, it melted and rose through the land plate, kind of like a lava lamp, and erupted at the surface, creating a volcano. When the tectonic plate moved, the hot spot remained in the same location, and created a second volcano. As the plate continued to move and other volcanoes were formed, a volcano chain was created.

How many major volcanoes form the cascade mountains?
Penis Butt
The hawaiian islands are a chain of volcanoes that form over?
that were formed over hot spots
What state has the cascade mountains and Mount Rainier is in it?
The Cascade volcanoes stretch from British Columbia, Canada to California, United States. Mount Rainier is among the Cascade volcanoes and is located in the U.S. state of Washington.
What are groups of volcanoes called?
If it is a single island, it is simply known as a volcanic island! If however it is a chain or string of separate islands then it may be a volcanic island arc (these form parallel to trenches at subduction zones) or a volcanic island chain (these form where a mantle plume creates a hotspot and may be in the centre of a tectonic plate. A good example would be the Hawaiian island chain). They can also form a cluster of islands (an archipelago) such as the Canary Islands (again formed by hotspot volcanism) in the Atlantic of the coast of Morocco.
Which of the following locations is composed of intraplate volcanoes?
I have a strong feeling it is cascade range.
How are Lassen peak and Mount Shasta related to subduction?
these volcanoes are the southernmost volcanoes of the cascade volcanic chain.

How did Cascade Mountain range form?
The Cascade mountain range is made up of a band of thousands of very small, short-lived volcanoes that have built a platform of lava and volcanic debris. The volcanoes were formed on a subduction zone where the Juan de Fuca oceanic plate plunges beneath the North American Plate. Magma was forced toward the Earth's surface to erupt, forming a chain of volcanoes - the Cascade Volcanic Arc - above the subduction zone.
Where volcanoes form with two oceanic plates collide may form a chain of volcanoes is called what?
The path of three over two divided

Does Montana have volcanoes?
There are no active volcanoes in Montana. You have to go further west to the Cascade Range to find volcanoes. The volcanoes in the Cascades are caused by the subduction of the oceanic crust under the continental crust.
