Reflection on our unit

Our last unit was fairly fun and interesting. Our unit was about: Rocks, Minerals, Caves, Volcanoes etc. I learned a lot abut minerals for Ex: There are a lot of types of minerals. Minerals are mostly used for:jewlary, technology, cars etc. Minerals form from Volcanos. When the Volcanos erupt after a few hours the lava cools which forms rocks, minerals or minerals in rocks. They can also form by inorganic proceses. You measure the minerals hardness by a scale called the Mohs Scale. 

I also learned About volcanos a fair amount Ex: There are 3 types of volcanos: Cone, Shiled and Stratvolcano  and also the Biggest Eruption was Mount St. Helens.

I almost forgot about the rock cycle: There are 3 types of rock: Metamorfic rocks, Sedamentary rocks and Igneous rocks.

Before i finish this post I would like to point one thing and that is The Earths Structure . There are 3 main layers of the Earth called: Crust,Mantle,Core but there are also some minor diffrences like there is the inner and outer core and the is a mantle and lower mantile. The crust is the outer layer of Earth where we: walk on drive on etc. The matile is the middle layer and it is solid but some of it is liquid. and last but not least we have the core. It is the most hottest layer in the Earth which is 3500°C.

So as you can see our unit was very fun and i enjoyed it and i learned alot.
