Using the BIG6 steps, we must make a list of "Why" questions about the natural disaster that our group chose. Finally, without arguing, we decided on Volcanoes. Together, we finally completed the list of "Why" questions. We also worked really hard on our Scratch, Glogster, KeyNote, etc., so we hope you enjoy them!

List of FAQ and Answers:

1. Why do volcanoes erupt? When the rock inside the Earth becomes hot enough, it melts. (That molten rock turns into something called magma.) The rock that melts is less dense than the solid rock surrounding it, and it will rise to the surface of the Earth, just like if something is less dense than water it will float on top of the water. The magma rises to something that's called the magma chamber, and if the pressure continues to increase on the magma in the magma chamber, it will result in an eruption.

2. Why is lava red? Lava is red because anything that's 1200 to 1400 degrees Fahrenheit will turn red. The molten lava in the volcanoes are usually really hot and fresh. It will often be hot so it will appear rather white than red. If it is no longer red, it will have enough heat radiation that you can still feel on the the side of your face or hand, even from a long distance. That is like the color red so you will see the waves and that is how you can feel.

3. Why do some volcanoes don't erupt anymore? Several volcanoes have not erupted in thousands of years. One reason for this is because the volcano vents and conduits become plugged up with the hardened lava. In strato volcanoes the plugs can bottle up magma chambers for hundreds to thousands of years. The rocky cores are hard to pop, so when they finally let loose, it lets off a tremendous amount of energy.

4. Why is lava so hot? Lava is a form of hot molten rock, which comes from a volcano during an eruption. Lava is a very viscous liquid from the volcanoes. It is 100,000 times the viscosity of the water, which is how it flows great distances. The lava in the volcano can flow over several miles because of its viscosity. This is why some volcanoes in Hawaii have the lava flow into the sea.

5. Why do volcanoes form? Volcanoes form when hot molten rock, ash, and gases escape from below the planet's surface. When this happens, it tends to form mountains or volcanoes. Volcanoes tend to form around "Hot Spots". A hot-spot is where the earth's crust is thinner than other areas, thus making it easier for hot molten rock, ash, and gases to escape from below the planet's surface. Most hot-spots form underwater.

6. Why do some volcanoes erupt more than other volcanoes? Some volcanoes erupt more than other volcanoes because the amount of gas in the lava. And other factors can be cooling down causing rapid fracturing.The volcanoes have different amount of gas in it so they have different timing.

7. Why are volcanoes called “active” even when there’s no eruption? They are called active, since they can erupt any time. That is why they are called “Active”. If there is no signs of activity, then then it would not be called active. But however, if there is signs of volcanic activity, even though there is no eruption the volcano is still active.

8. Why are volcanoes filled with lava? Volcanoes are filled with lava because of the heat inside the volcanoes. The heat creates a very hot atmosphere, thus melting the rock, making magma or better known as lava.

9. Why do volcanoes form at plate boundaries and hot spots? Volcanoes form at plate boundaries and hot spots, because the plates under the earths crust are always moving, and sometimes the plates crash into each other. This sometimes makes one plate sink under the other one and burn up, or push up on each other which forms volcanoes.

10. Why can some volcanoes form on Mars? Mars is only one half of the size of Earth and there is several volcanoes that surpassthe scale of the biggest volcanoes.Both Mars and Earth have volcanoes because it has a big place to let the lava flow.The eruptions are usually quiet in nature,but sometimes in these places,they are also quiet too.The long hot lava flows between Martian and Terrestrial .The volcanoes there are in sizes.The magma chambers will be deep in the Martians crust.

Alot of our information came from free websites such as Answers.com, Wikipedia, and google search.

We read all of the questions (1-10).All of the answers are correct because it answers the question. We understand all of the sources.The answers are the important information that we need to know about Volcanoes.

5.1
When we were doing the nature's fury project,we put our brains together and came up with ideas.someone came up with an idea but we weren't sure if it is good so another person from our table group said a different thing and we agreed.We made note so we won't forget what our ideas was.We worked together so we could finish all of the ideas we needed for the nature's fury project.All of the notes,ideas we wrote down,helped a lot for this project.

6.1&6.2
When we were doing the Nature's Fury project,we worked together to finish the project.In the beginning, we were a bit far behind,but when we realized that in order to finish a project,we had to work together.Some people in our table wasn't sure what to do next because he was already done with his other thing,so he asked and figured out what he need to do.
