Plate Tectonics

Master plate tectonics! Understand boundary types, from collision to separation, and their geologic impacts.

Plate Tectonics Watch the video and then use this information and your notes to complete the remaining parts. Match the plate boundary to the image Transform Convergent Divergent Sort the following into the correct plate boundary Each group will have between 3-5 when done. Oceanic Divergent plates move away from each other New crust is formed magma rises between two plates Mid-Ocean Ridge Mid Atlantic Ridge Convergent Continental to Continental (collision) Creates folded mountains Himalayas Two Continental plates move towards each other Crust is deformed Transform Plate slide past each other San Andreas Fault Known for creating earthquakes Convergent Oceanic to Oceanic (subduction) Volcanic island arcs An oceanic plate slides under another plate Trenches Crust is destroyed Continental Divergent Contintental plates moving away from each other Magma rises to form new crust Iceland Rift Valley Convergent Oceanic to Continental (collision and subduction) coastal volcanic mountains An oceanic plate slides uner a continental plate trench Crust destroyed Plate Boundary Matching Match the different types of plate boundaries with the correct picture. Continental Continental Convergent Oceanic Oceanic Convergent Transform Oceanic Diveregent Oceanic Continental Convergent Continental Divergent Use the word bank to fill in the blanks. When an oceanic plate converges with another tectonic plate, it will go under the other plate. This process is called subduction. The subducting plate melts into the magma within the mantle and the crust is destroyed. This process always results in the formation of ocean trenches. When two continental plates converge, they buckle and collide. This forms mountainsand the crust is deformedas a result.When two plates pull apart from each other, this is known as a divergentboundary. The gap that is formed is filled as magmarises from the mantle. This magma then cools and hardens into new crust. The crust that is closest to the boundary is the younger and the crust further away is older. When this occurs on the ocean floor, the process is called sea floor spreadingand it forms underwater mountains known as mid-ocean ridges. On the other hand, when this occurs on land, it forms a rift valley. When two plates are moving past each other, this is knows as a transformboundary. This results in a fault line and is usually associated with earthquakes.The ring of fire is an area of plate boundaries circling the Atlantic Ocean known for exceptionally high levels of plate tectonic activity, including volcanoesand earthquakes.
