Week 10

 Lab - This week in lab we started to look at the three categories of rocks, sedimentary, igneous, and metamorphic. We were tasked recreating these rocks through their individual process using starburst. We went through the process of melting and molding the starburst in different way to recognize the differences in outcomes. Below are our final rocks! 

Press Book - This week in our textbook we learned about Earths four layers the crust, mantel, outer core, and inner core. The crust is made ip of rocks such as basalt and granite. The crust is also the thinnest of the layers. The crust is also broken into two types of plates: continental and oceanic. The mantle is the thickest layer of the Earth, containing magma.  The outer core is liquid containing iron and nickel. The inner core is completely solid because of how seismic waves from earthquakes travel through the interior of Earth.

The press book also discusses convergent plates and divergent plates. 

This week in lecture, we learned about the different layers of the earth, inner and outer core, the mantel, and crust. We also learned about the cycle of sea floor spreading. This occurs at the mid-atlantic ridge, where the middle of the ridge is fresh and hot. Where the farther you go either direction from this point the cooler and older the floor is as it gets pushed farther out from the new floor.
