What evidence is there that the plates have moved?

Some evidence there is about the plates is that if you put our continents all together, they look like they'd fit together, like a giant puzzle. Another thing is that on some edges of the continents, the same fossils were found, suggesting that the continents were once joined together. These plates are called tectonic plates, and move slowly, and then sink down in most cases. Convection Currents are vertical movements of fluids driven by heat. There are three different types of boundaries: Convergent, Divergent, and Transform. The two plates are Oceanic and Continental.

Eroding its way out of your heart!

Erosion

Erosion is the process of being eroded, or steadily destroyed, by wind, water, or other natural events or things. The types of erosion are Water, Wind, Glacier, Soil, and Sea erosion. The erosion that causes the most damage is Glacier. A combination of water, ice, and picked up sediment creates a powerful erosion machine. The least damage created erosion is Soil. Soil erosion takes the top layer of soil and makes it infertile. It creates less food and plants for us, but nothing is destroyed.

Fossils are us. (Or they used to be)

Rocky Road (And Minerals!)

The Rock Cycle

The Rock Cycle is a cycle that rock go through. It can change Igneous Rock to Metamorphic Rock, and vice versa. For example, Igneous Rock changes to Sedimentary Rock through Weathering, Erosion, Burial, and Compaction.

Minerals.

Minerals form from decaying organisms and as a result of changes in the Earth's crust. We can identify minerals by their colors, shapes, sizes, streak, luster, or hardness.

Things I have enjoyed

I have enjoyed many things about the activities in this unit. The best thing was probably doing this flyer, seeing as it was very fun. The stations were also pretty rad. :3
