What I Learned


The plates can move by compression which is when the rock pushes together. Also shearing which is when rock slips past each other. Then there is tension which stretches the rock. The boundary convergent is when two plates converge. The place where two plates diverge is called the divergent boundary. A transform boundary is when plates slip past each other. It is part of earths lithosphere that are in slow constant motion. It is driven by convection currents in the mantle.


Erosion is when running water, ice, and wind and carry away fragments of rock. It weathers a lot of rock on the earths surface. The three main types are water, wind, and ice. The type of erosion that changes the earths surface the most is water. The one that causes the least change on earth is ice.

Rocks and Minerals

The cycle

If you start with a igneous and apply heat and pressure it makes a metaphoric rock. Then erosion can happen and then deposition can happen to make a sedimentary rock. Then it can melt to form magma and lava. Then If volcanic activity happens it can form a igneous rock.

A mineral can form by geode is a rounded hollow rock that is often lined by minerals. Crystals form inside a geode when water containing dissolved minerals seep into a crack or hollow in a rock. Then slowly crystallization occurs, lining the inside with large crystals. Crystallization is when atoms are arranged to form a material with a crystal structure. They can also form when hot magma cools inside the crust, or as lava hardens on the surface. When these liquids cool to a solid state, they form crystals.

What i liked

I liked the fossil centers because we get to move along the classroom. Also I liked watching the earthquake video.
