Geology: The rock cycle, This is my favorite topic because I didn't know how many cycles there are. I didn't know how rocks can become other types of rocks. For example, metamorphic rock becomes sediment through erosion and sedimentary rock becomes magma and lava by melting. Any rock that becomes sediment goes through erosion and any rock that becomes magma and lava has to melt. I was surprised when I learned that what rocks have to do to become other types of rocks.
Weathering and Erosion: The types of weathering, This is my favorite topic because I didn't know how many ways weathering can happen. I learned that it happens through water (waves, too), wind, and glaciers. I didn't know that waves break down the land that it hits. Also, I didn't know that wind could break down rocks, it's real slowl, but it happens. Glaciers can erode rocks by plucking where they pick up rocks when moving. There's mechanical and chemical weathering. Mechanical is caused by something physical hitting the rock and chemical weathering is caused by liquids wearing down the rock.
Earth's Waters: Wetlands, This is my favorite topic because I think that wetlands are interesting. You never know when you're walking through one and all of a sudden, splash, an alligator splashes out, or you here something in the bushes, a racoon is looking for a meal. I found the different types of wetlands interesting, especially bogs. I never new that bogs have acidic waters. Ther moss makes them look like feilds, but they're not. I also thought that the Florida Everglades were interesting. I didn't relize how many species of wildlife it contained and all of the threats that there is of destroying it. To me, wetlands are interesting because you never know what is in them and what you will stumble apon.
