The Cascade volcanoes form what is known as a continental volcanic arc. Off the west coast of the U.S. and Canada a section of Earth's oceanic crust is colliding with the North American Pate and sinking into the mantle beneath it. As it moves down it takes some seawater with it. This seawater seeps into the hot rock of the mantle, altering its chemistry and allowing some of it to melt. This magma then rises through the crust to erupt from volcanoes.

Why does the cascade range have so many volcanoes?
volcanoes typically happen along earth's tectonic plates. the plates move and shift, creating both volcanoes and earthquakes. Volcanoes may also occur in the middle of plates or even over hot spots :D
What are the Cascade Range in Washington and Oregon caused by?
The Cascade Range in the Pacific Northwest is caused by the convergent plate boundaries they sit on. So when an earthquake occurs, it causes the plates to dive down beneath the other plate causing the land to "push up" and thus forming mountain ranges for example.
How many underwater volcanoes are there?
Experts estimate there could be around 3 million submarine volcanoes in the world. Due to constant shifts in plate tectonics and the amount of inactive/unidentifiable volcanoes, the exact number is unknown.
What state has the least volcanoes and how many volcanoes?
Many states don't have a single volcano so it's hard to tell which state has the least amount of volcanoes.
Is there any volcanoes at the jungle?
There are volcanoes in the jungle. It just depends on what part of the jungle you are in. Many of those volcanoes are still erupting today. So, the answer is yes.

Why do you have so many range in California?
There are many mountain ranges in California because of tectonic forces like earthquakes or volcanoes.

How many volcanoes are erupting?
Not many about 10. this is just my guess so...

Where are the volcanoes in Jamaica?
This question could be split two ways. 1. Does Jamaica have any dormant or extinct volcanoes? Yes. Jamaica and surrounding islands of the Antilles were in fact formed from volcanoes. These volcanoes rose from the ocean billions of years ago to form the islands that we know today. So, in a sense, the entire island of Jamaica is a volcano. 2. Does Jamaica have any active volcanoes? No. There are no active volcanoes on the island of Jamaica. There are, however, many mountains in Jamaica's Blue Mountain Range.
Why don't we have volcanoes in North America?
volcanoes usually form at the edges of tectonic plates, which is one of the reasons that there are many in the Ring Of Fire. North America is not really located at the edge of many plates so there are not that many volcanoes.
Why do so many of earths volcanoes occur along plate boundries?
Volcanoes occur near plate boudaries because volcanoes need water to erupt.
Why are there often so many steps between the original signal event and the cell's response?
Each step in a cascade produces a large number of activated products, causing signal amplification as the cascade progresses.
Why is the pacific ring of fire so significant?
beacuse there has been so many volcanoes.
