Rock Cycle By Maya Berry and Miley Krum

Different Rock Types and How They're Made

Igneous Rock (Snowflake Obsidian)

Igneous rock is formed when magma cools and solidifies, it may do this above or below the Earth's surface. Magma can be forced into rocks, blown out in volcanic explosions or forced to the surface as lava. Resulting in this shiny and glassy like texture.

Metamorphic rock (Gneiss)

They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks. Sometimes, metamorphic rocks are formed when rocks are close to some molten magma, and so get heated up. Remember that metamorphic rocks are not made from melting rock.

Sedimentary (rock salt)

Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers turn into rock. Sedimentary rocks can be formed in deserts , lakes, rivers and seas.

My Reflection

I think that observing the rocks made me have more of an understanding of how easy it is for the rock cycle to start.Because I thought that it took a very long time for the rock cycle to start but it's only a month or two when I thought about it. Also I thought that it was interesting that the only rock that I could find were sedimentary rocks and rocks that were weathered.

Like these rocks

I think that it is important that my neighborhood has lots of dirt so that the process of sedimentary rocks can be made because sedimentary are the only rocks that I saw, besides the rocks that were bought and purposedly placed.Also I thought that it was interesting how two years ago I put sedimentary rocks purposely in the water of the picture above and every year they get dramatically smaller, and I think that is how I got a way better understanding of how rock get weathered and eroded.
