1. Take a minute to read through the names of each of the volcanoes and their characteristics.

Simplest type of volcano, rarely rises above 1000 feet,

typically has a bowl-shaped crater at the top, found

in western North America

Some of the Earth’s grandest mountains, typically have steep

sides and symmetrical cones, most have a crater and vent at

the summit, made up of alternating layers of lava and ash

Built almost entirely by fluid lava flows, typically has a

gentle slope, generally erupts slowly over a long

period of time

Formed be small, bulbous masses of lava too thick to flow a great distance, lava piles around the vent, some domes form

craggy knobs or spines over the volcanic vent

Where do Volcanoes Form?

There are three main places where volcanoes form: hot spots, divergent plate boundaries (such as rifts and mid-ocean ridges), and convergent plate boundaries (subduction zones).

The source of the magma for hot spots is not well known. We do know that the magma comes from partly melting rock within the upper mantle. This is probably from depths not much greater than 100 km. However, the actual hot spot goes much deeper than that. Hotspot volcanoes formed the Hawaiian Islands.

At a divergent boundary, two tectonic plates are moving apart. Magma that is made in the upper mantle flows upward to fill in the space. This magma is probably made at depths that are lower than those for hotspot magmas.

People disagree about whether the magma causes the plates to move apart or if the plates move apart first and the magma fills in the space. Perhaps it is a mixture of these two. The most widespread example of this type of volcanism is the system of mid-ocean ridges. On land the East African Rift is another example of divergent boundaries.

The final major place where volcanoes originates is at convergent boundaries (subduction zones). This is where an oceanic plate dives under either another oceanic plate or a continental plate. The underneath plate begins to melt because of friction. As a result, the magma begins working its way to the surface. This creates volcanoes either in the ocean or on the continents. The Cascade Volcanoes in the Pacific NW of the U.S. are examples of this type of volcano. An Island Arc of volcanoes can form when two oceanic plates come together.

Where would you least

likely find a new

volcano?

A. Mid-ocean ridge

B. “Hot spot” in Hawaii

C. The great plains in the middle

of the U.S.

D. Near a subduction zone in

Argentina

How do volcanoes

form near a

divergent boundary?

A. Magma fills in the gap where the plates

move apart

B. Magma is created by a subduction zone

C. Magma breaks through the tectonic

plate above a “hot spot”

D. Mountains erode away and create a

volcano

A _________________ is

formed when one

tectonic plate dives

underneath another one.

Which statement

can be concluded

after reading the passage?

A. There are many volcanoes formed near

plate boundaries.

B. Volcanoes are created by erosion and

weathering.

C. A convergent boundary must be present

to form a volcano.

A. Hot spot

B. Subduction zone

C. Rift valley

D. Divergent plate boundary
