Explore the science of plate tectonics, where Earth's lithosphere undergoes vast movements, forming diverse boundaries and geological features like mountains and volcanoes. Learn about continental drift, convergent and divergent plate boundaries, and transform faults. Dive into the formation of the Himalayan Mountains and the volcanic line along South America's western coast. Witness the subduction process at oceanic-continental plate boundaries and the creation of volcanoes. Discover how Earth's lithospheric plates fit together like jigsaw puzzles above the mantle. Watch our educational video!

Log Twelve Debrief Plate Tectonics
Plate Tectonics • Greek – “tektonikos” of a builder • Pieces of the lithosphere that move around • Each plate has a name • Fit together like jigsaw puzzles • Float on top of mantle similar to ice cubes in a bowl of water Plate tectonics is the scientific theory that describes the large scale motion of Earth’s lithosphere.
Continental Drift • Continental drift is what we see… • Plate tectonics is what is happening.
Convergent Plate Boundary Types • two plates move toward each other and collide. • Continental vs. oceanic plate convergence • Oceanic vs. oceanic plate convergence • Continental vs. continental plate convergence
Divergent Plate Boundary • A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface. Arabian Plate Red Sea African Plate
Transform Fault • Places where plates slide past each other are called transform boundaries.
Question One 1.Identify and explain the process that is forming the high non-volcanic mountains at location 1 on the map. Eurasian Plate Convergent Plate Boundary Indian Plate Himalayan Mountains Forms
2.A line of volcanoes occurs along the western coast of South America, near location 4. Based on the information about plate movement on the map, identify and explain the process that formed these volcanoes. Question Two Also a convergent plate boundary, but this boundary is between an oceanic plate and a continental plate. The oceanic plate will slide under the continental plate. This is called subduction. This will create volcanoes. More later. Watch this video!!!!
