PLATE MOVEMENT Ms. Sikes

Bell Ringer In the bucket is a quiz for you to take. You need to put the quiz on a new sheet in your bell ringer folder. When you are done turn it in to your period’s basket. Grab the notes from my desk and put them into your science notebook. You may grab a textbook from the cubby and begin filling in the notes. Pg 400.

Plate movement Continental Drift is the hypothesis that states that the continents once formed a single landmass, broke up and drifted to their present locations. The single landmass that was once proposed to hold all of the continents together was called Pangea. Continental drift also explained why fossils of the same plant and animal species are found on continents that are on different sides of the Atlantic Ocean.

SEA FLOOR MOVEMENT Mid- Ocean Ridges are underwater mountain chains that run though Earth’s ocean basins. This is where sea-floor spreading occurs. Sea- Floor Spreading is the process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies. Below draw a picture of a divergent boundary and sea-floor spreading occurring.

SEA-FLOOR SPREADING

EVIDENCE FOR SEA-FLOOR SPREADING: MAGNETIC REVERSALS North and South Poles reverse their places. Evidence of this taking place is from tiny grains of magnetic minerals like iron that work as compasses. They align with the magnetic field of the Earth and provide record of magnetic reversals and sea-floor spreading.

TECTONIC PLATE BOUNDARIES: CONVERGENT Continental-Continental Collisions: is when two tectonic plates with continental crust, collide, they buckle and thicken, which pushes the continental crust upward. These collusions cause mountains to form.

TECTONIC PLATE BOUNDARIES: CONVERGENT Continental-Oceanic Collisions: When a plate with oceanic crust collides with a plate with continental crust. The denser oceanic crust sinks into the asthenosphere. This creates a subduction zone where old ocean crust gets pushed into the asthenosphere, where it is remelted and recycled.

TECTONIC PLATE BOUNDARIES: CONVERGENT Oceanic-Oceanic Collisions: When two tectonic plates with oceanic lithosphere collide, one of the plates with oceanic lithosphere is subducted , or sinks, under the other. Creates a subduction zone

TECTONIC PLATE BOUNDARIES: DIVERGENT Creates volcanoes and mid-ocean ridges

TECTONIC PLATE BOUNDARIES: TRANSFORMING Creates fault lines and earthquakes

Assignment Divergent Title Convergent (continental to continental) Title Describe what happens (what kind of plate runs into what kind of plate) Draw a picture What is formed at this boundary? Explain WHY that is formed at this boundary Convergent (continental to oceanic) Convergent (oceanic to oceanic) Divergent Title Describe what happens (what do the plates do?) Draw a picture What is formed at this boundary? Explain WHY that is formed at this boundary Transform What is formed/what happens or is produced at this boundary? Explain WHY that is produced at this boundary.
