In Mad Science we learned about rocks. Asteroid Adam thought us about igneous rocks, metamorphic rocks, sedimentary rocks, and conglomerate rocks.
We also learned about volcanoes. In the middle of the volcano is called lava. There is also some molten rocks.
We learned about earthquakes too. Scientists use a scale (1-10) to measure how strong an earthquake is. If an earthquake is between one and three we probably won't feel it. If it is between four and six they get a little worried. If it is between seven and ten it can break anything that it hits.
We learned about Earthworks. Geodes are the same thing as crystals. We learned about the crust, mantle, and the outer core and inner core of the Earth.
