**Vocabulary**
volcano- a place on Earth where it is weak and lava comes out there. magma- a molten thing which includes gas, water, and molten rock. lava- a magma which came out to the surface. Ring of Fire- the major volcanic belt where a lot of volcanoes comes in circle. island arc- a line of island which is created by same volcano. hot spot- a big place underground where magma is stored.

**What is a volcano?**

 * Where the volcanoes form are the weak spot on Earth where the lava comes out.
 * When lava cools, it becomes to solid rock.
 * Volcano is one of the constructive forces.

**Location of Volcanoes**

 * There are about 600 volcanoes on land.
 * There are many more volcanoes underwater than on land.
 * Volcanoes occurs in belts.
 * The major belt is Ring of Fire.
 * Most volcanoes are formed near plate boundries.
 * Near the subduction zone, and plate boundries.

**Volcanoes at Diverging Plate Boundries**

 * Most volcanoes form near the plate boundries.
 * It is because the plates melt and the molten material comes up to surface and becomes magma.
 * The volcanoes underwater on plate boundries may form a strings of island called island arc.
 * The major countries with volcanoes are Japan, Indonesia, New Zealand, and some other countries.

**Hot Spot Volcanoes**

 * A volcano which is not near the plate boundries all have hot spot.
 * The hot spot has a lot of magma for the volcano to erupt.
 * The Hawaiian Islands are made from one volcano which has a hot spot.
 * Hot spot can also be under the continents.
