Earth Science Course 1 Grade 6-12
Level 2 Course 1
The Course 1 Earth Science topics and textbooks are designed for students in 6th – 12th grades. This advanced Earth Science course includes information on the structure of our planet and how it is created.
The lessons in the advanced course includes information on plate tectonics, the rock cycle, subduction zones supervolcanoes, and megathrust earthquakes.
What is the Rock Cycle
The Rock Cycle is the never ending creation and destruction of rocks that occurs on our planet. Igneous rocks were all derived from magma, molten rock that cooled into solid rock. There are three major groups of sedimentary rocks. Clastic rocks are bits and pieces of older rocks that have been formed into new rocks. Organic rocks include coal and coral reefs. Chemical rocks, like salt, crystallize when older rocks dissolve and the minerals crystallize in shallow oceans or dried inland lakes. Metamorphic rocks form when heat and pressure causes older rocks to recrystallize without melting into new rocks. Course 2 materials also available.
