Constructive and Destructive Earth Processes
Todays Essential Question How does our Earths crust continue to change?
Todays Key Vocabulary landform : feature found on the continental crust crust: upper layer of the Earth
Vocabulary Plate Tectonics: The theory that the Earths crust is made up of plates that fit together like a puzzle and that these pieces are in motion.
Vocabulary plate: A piece of the Earths crust.
Vocabulary fault: The place where two plates meet. San Andreas fault in California
Lets take a closer look at the crust and why scientists think it is moving!
Georgias Fault Line The Brevard Fault runs southwest to northeast through Alabama, Georgia, and North Carolina. Scientists believe that it may have once been where the African continent joined the North American continent.

Constructive Plate Movements Constructive plate movements build-up the Earths crust. Mountains video clip Volcanoes video clip The_Birth_of_Lizard_Island video clip
Types of Constructive Plate Movement mountains : formed when two plates collide islands and volcanoes: formed when one plate slides under the other or when two plates pull apart and magma builds up Interactive volcano
Ring of Fire The Pacific Ring of Fire is an area where large numbers of earthquakes and volcanic eruptions occur in the Pacific Ocean.
Georgias Stone Mountain Stone Mountain is located near Atlanta, Georgia. It was formed during the formation of the Blue Ridge Mountains. Scientists believe that magma swelled up from the Earths crust and hardened into a granite dome.
Destructive Plate Movement Destructive plate movement tears down the Earths crust Earthquakes video clips The_Eruption_of_Mount_Saint_Helens_in_Washington_State video clip
Types of Destructive Movements earthquakes: formed when two plates slide past each other volcanoes: volcanoes both build-up the Earth with lava and tear down the Earth with its eruptions.
