Section 1

What are the three types of volcanoes?

Shield Volcanoes

• These volcanoes are low and flat and have flowing eruptions. As the lava builds up on the volcano it becomes larger.

• Shield volcano

Composite Volcanoes

• These volcanoes have tall mountain like structures. Mount St. Helens was a famous composite volcano. A crater at the top is where the lava flows out.

• Composite volcano

Cinder Cone Volcanoes

• These volcanoes are the simplest kind of volcanoes. They have a bowl-shaped crater where lava comes out.

• When lava flows over the top it creating the rocks called cinders.

• Cinder cone volcano

Section 2

Why do volcanoes occur?

Occurring volcanoes

• Volcanoes occur when the Earths plates pull apart causing magma to rise to the surface. This is called plate tectonics.

What is plate tectonics?

Plate Tectonics

• Plate tectonics is the study of the motion of the plates in the Earths crust. The Earths tectonic plates are in constant motion.

Section 3

Where do most volcanoes occur?

• They form around the Pacific Ring of Fire.

• There are many volcanoes in Hawaii also.

• Pacific Ring of Fire

How did the Pacific Ring of Fire get its name?

Pacific Ring of Fire

• The ring of fire is roughly shaped like a ring. It marks the area of the greatest seismic activity in the world.

• Tons of volcanoes occur here everyday.

How do volcanoes form?

ERUPTION!!!

• A volcano is formed when magma comes up from the Earth and through the cracks in its surface.

• A volcanoes magma makes up the Earths surface.

• A volcano is really cooled lava.

• A volcano erupting

What is a hot spot?

Hot Spot

• A hot spot is a flow of magma that pushes through areas of weakness on the Earths crust.

• Picture of Hot Spot

Section 4

What is a volcano hazard?

Volcano Hazards

• Danger from a volcanoes destruction is called a volcano hazard.

• In the past 500 years 200,000 people have lost their lives due to volcanoes.

• Destroyed homes

What hazards can volcanoes produce that effect people?

Destruction

• The accumulation of ash can affect peoples lungs.

• The ash is so small that it can easily get in your lungs.

The ash

How do you get prepared for a volcano?

Pack a first aid kit.

• For the first aid kit you should provide the following:

• Flashlight• Extra batteries• Extra food and water• Medicines• Dust mask

Section 5

What is our favorite volcano in history?

Mount St. Helens

• During the past 4,000 years, Mount St. Helens has erupted more frequently than any other volcano in the Cascade Range.

• Most of Mount St. Helens is younger than 3,000 years old.

Mount St. Helens

• The first sign of activity at Mount St. Helens in the spring of 1980 was a series of small earthquakes that began on March 16.

Section 6

What is our favorite presently active volcano?

Mount Aso

• Mount Aso is one of the largest volcanoes from those seen all over the world

• This active volcano is located in Japan on an island called Kyushu.

• Mt. Aso’s crater

How do people live by Mount Aso?

People’s lives

• There are many big cities close to active volcanoes.

• People don’t seem to mind it that they could be apart of a huge disaster at any time.
