VOLCANOES By Maya Bailey, Kylie Briand, Sol Garcia, Nora Olson


There are many types of natural disasters, but some of the worst have been volcanoes. Ever heard of Pompeii? Mount St. Helens? These were horrible volcanic disasters! First, you’ll learn about what volcanoes are, how they are formed, why they erupt, different types, where they are most commonly located, famous volcanoes such as Pompeii, and volcano vocabulary!

Have you ever wondered what a volcano is?

By: Sol

A mountain could open into a molten rock underground. Sometimes a pressure could build on a eruption. Pressure could form gas and water also steam. On a eruption can cause lateral blast lava flows mudslides avalanches falling ash and floods. If you want learn more about volcano go to wiz kids weather.

How volcanoes form

By: Kylie

Have you ever wondered how volcanoes form? In the article weather wiz kids it states that every time a volcano erupts it will get bigger and bigger. Volcanoes can also form when high temperature and pressure causes the rock to melt and become bigger. another way they can form is when a vent in the earth's crust allows magma to build up from below. In the article how do volcanoes form it states that when magma cools it makes a volcano. In the article why do volcanoes form it says that they can also form when a slowly rises through the water. If you liked that you can continue reading the article and find out why volcanoes erupt!

Have you ever wonder why volcanoes erupt?

One thing about a volcano the earth is crust is made up a huge slabs called plates. The friction causes earthquakes and volcanic eruption in edges of plates. The theory that explains is called plate tectonics. Also a lava could build up.

Different Types

By: Nora

Have you ever been by a volcano that once erupted, and wondered what type it is? There are 4 different types of volcanoes.

One type of volcano is the Cinder Cone. On the website Universe Today, it states that Cinder Cone volcanoes are the most simple type. When they explode, lava flies in the air. They are rarely 1,000 ft above their surroundings, and they build an oval-shaped cone.

Also from Universe Today, it states that the second type of volcano, the Composite or Stratovolcano, is a volcano that has vents or pipes in which magma wells and then channels up. The lava may break through the walls so if you see lava pouring out of the sides of a volcano, you know that it is a Composite volcano. They can be thousands of meters tall and some of the most famous Stratovolcanoes are Mount St. Helens, Mt. Rainier, Mt. Fujii, and Mt. Cotopaxi. On a National Geographic Video it states that these are very common.

A third type of volcano is the Shield Volcano. On Universe Today, it says that this type was named Shield Volcanoes because from above they look like shields. They produce thin lava, so it can travel great distances. They have shallow slopes and they slowly build up over time. They erupt hundreds of times and they have many layers. Most likely, if one is going to erupt it will be a smaller eruption. There make up the Hawaiian Islands, and are more popular than other types, according to the National Geographic Video.

The final type of volcano is the Lava Dome. Universe Today states that they are made by small masses of thick magma that travels short distances, slowly. Magma piles over and around the vent.

Lava Domes grow by by the lava within expanding and they form from the materials on the sides. Stay away if there’s the possibility of one erupting because they violently erupt and send hot ash and rocks through the air.

If this has helped you learn about the different types of volcanoes you can continue to read and you can learn where volcanoes are most commonly located.

Where Volcanoes are Commonly Located

By: Nora

Have you ever seen a Volcano before? Where were you? Why was it there?

Volcanoes are formed around Earth’s shifting plate boundaries, according to Geoscience Australia. On that website, it states that volcanoes can be found in New Zealand, Papua New Guinea, Indonesia, and the Philippines. Weather WizKids states, in the USA, some common places for volcanoes to be are Hawaii, Alaska, Oregon, California, and Washington. There are also quite a few volcanoes in the Caribbean, and in Japan. Study.com says that volcanoes are located on the plates because they shift, push, and pull, causing volcanoes to form and later explode.

Now, you can read about some of the most famous volcanoes, because you already know where volcanoes are most commonly located.

Famous Volcanoes

By: Maya

Have you ever seen Mount St. Helens because not only is it a mountain but also a volcano and was the most economically destructive volcanic event in the history of the United States!

One famous eruption in Pompeii is the eruption of Mount Vesuvius. On the website History.com it says that it erupted in Italy, an ancient roman city. Mount Vesuvius erupted on August 24 74A.D. It has erupted dozens of times in the past 2,000 years. First Mount Vesuvius ejected a large cloud of debris into the atmosphere, and Wikipedia said it also included molten rocks, pulverized pumice, and hot ash as hot as 1300° at the rate of 1.5 million tons per second. Also History.com states that the debris was going down the volcano at 70 miles per hour for 24 hours and destroyed everything in its path.Another famous volcano is Mount St. Helens. On the article ngdc.noaa.gov it states that Mount St. Helens is in Washington, it’s a stratovolcano aka composite volcano, and it was the most economically destructive volcanic event in the history of the United States. It erupted in 1980. Also History.com says it caused a massive avalanche that killed 57 people! Ash blasted 10,000 feet in the air. Some of it came down nearly 300 miles away in Spokane, Washington. Ash caused static electricity and lightning bolts! The authorities issued a hazard watch for 50 mile radius around Mount St. Helens. Throughout April many scientists watched a bulge on the mountain get larger and after time on may 18 at 8:32 am and earthquake and eruption rocked the mountain. The north side burst and blasted out ash at 650 mph. Ash, rocks, gas and glacial ice tumbled down the mountain at 100 miles per hour. 14 miles of the Toutle river were buried 150 feet deep in debris. Magma burning at 1300 degrees fahrenheit flowed out for miles, and ash came out for 9 hours. Mount St. Helens used to be 9,600 feet high but since the eruption it is now only 8,300 feet. The height changed in a matter of seconds. Another fact about Mount St. Helens that EarthObservatory.nasa states is from October 2004 to late January 2008 about 125 million cubic yards of lava had erupted onto the crater floor to form a new dome.

Now that you know about some famous volcanoes, it’s time to learn about the fancy words!

Fancy Words

By: Maya

Have you ever wanted to have a bigger vocabulary about volcanoes? This will explain some volcanic words.

One volcano related word is plate tectonics. Plate tectonics is when two plates that collide. Either one gets pushed up and forms a volcano or both push up and form a volcano.

Another word is pyroclastic flow. It blasts hot ash and rocks into the atmosphere, states kids fun science. Pyroclastic flow can travel at hurricane speed. They happened during giant volcanic eruptions. Kids fun science also says that lahar is volcanic MUD FLOWS. The contain lots of rocks so it looks and feels like flowing wet concrete. Also Kids.Britannica states that they can be triggered by events such as pyroclastic flow, rainstorms and the collapse of debris dams.

Now you know some volcano related words and their meanings!


We hope you enjoyed learning about what a volcano is, how they are formed, why they erupt, different types, where they are most commonly located, famous volcanoes, and a volcanic vocabulary. Now you know all these facts, so if you see a volcano, you’ll know all about it!
