Volcanoes - Science

Currently, we are learning about volcanoes in Science. We've done a lot of research on our blog topic which was to choose a volcano (worldwide) and learn about it. I chose...

Mount St. Helens

How do they form?

Volcanoes are formed when magma rises up from the mantle and reaches the earth's surface. Eventually, the magma (turned lava) will cool down and turn back to rock. It will continue this process and over time, so much rock would have hardened itself to form the mountain of the volcano.

Where is it located?

Washington, USA.

When did it last erupt?

10 July 2008 

How much damage was caused?

In 1980, a chunk in the side of the mountain collapsed, 57 people died, thousands of animals died, more than 200 homes were destroyed, 297 km of road and 24 km of railways were covered. But in 2008, there wasn't as much damage. 

Not too long ago, we chose our teammate's mountain (Mauna Loa) and created it out of 'paper mache'. We needed 4 spatulas of potassium iodide in 20ml of water, 35% of hydrogen peroxide, dishwashing liquid, green food clouring, and gold glitter. Reaction:  H₂O_2 ---> H₂O + O₂
