Welcome to Mi's page! On this page we will be talking about volcanoes! How they are formed and how they erupt.
There will be images too! We will also add links to where we found our information. To see where we got our images, click on it.

What is a volcano?
A volcano is a mountain that have different materials inside it, like lava, ash, cinder cones, and bombs. The material depends on which type of volcano it is. There are different volcanoes like shield, composite, and cinder-cone. How are they formed? They are formed when Earth's mantle melts rock turning it into magma. The magma rises to the surface and erupts! When the volcanoes erupt the bigger it gets because the lava hardens on it. For more information about it go to...

Shield Volcanoes
The picture shown is a shield volcano. Shield volcanoes are a long sloping mountain that doesn't have an explosive eruption. Instead of the lava coming out from the top, it comes out of a vent and hardens over previous layers. Did you know that the shield volcano Mauna Loa is one of the volcanoes that built the island Hawaii?
Below is a slideshow of different shield volcanoes. You will notice all of them are in Hawaii.

Cinder-Cone Volcanoes
Cinder cone volcanoes are steep, and coned shaped. They're are built by cinders. Cinders is a lava fragment.
They also grow fast and will soon reach it's maximum height. Cinder cone volcanoes rarely grow 250 meters high and 500 meters in diameter. An example of it is Paricutin in Mexico. For more information, click the link below.

Composite Volcanoes
Composite volcanoes are tall and cone shaped and have explosive eruptions that have ash, cinder and bombs. Did you know that the material may rise as high as 8,000 ft? Also, lava flows sometimes alternate with the eruptions. Examples of composite volcanoes include Mount Fuji in Japan, Mount St. Helens in Washington state. To see a video of Mount St. Helens, click the link below.
