Today we did a lab on the density of the Earth's layers. Earth is layered based on rocks that display certain characteristics. Because each these layers are composed of certain types of rocks, we found the mass and volume to get the density of the rock. We used basalt to represent the oceanic crust, granite for the continental crust, peridotite (which was in high demand!) for the the mantle, and iron for the core. After this information was found, we created a graph using Excel to plot the samples and find a best fit line for each. The slope of these lines told us the density of the "layers" of the Earth (or at least what the layers are made of).
Good luck on the quiz tomorrow!
The next scribe is Maren :)
