1 The Theory of Plate Tectonics - Boundaries, Stresses, and Faults 1. What is the theory of plate tectonics? 2. What are the three types of plate boundaries?
2 What are Plates? The Earth s crust and upper mantle (Lithosphere) are broken into sec:ons called plates Plates move around on top of the mantle like racs A sec;on of the lithosphere that slowly moves over the asthenosphere, carrying pieces of con;nental and oceanic crust.
3 What is the Theory of Plate Tectonics? The theory that pieces of Earth s lithosphere are in constant mo;on, driven by convec;on currents in the mantle. Plates move slowly in different direc;ons q Cause different geologic events (like earthquake, volcano, etc.)
4 What makes the plates move? Convec;on Currents in the mantle move the plates as the core heats the slowly- flowing asthenosphere (the elas;c/plas;c- like part of the mantle).

6 The edges of Earth s plates meet at plate boundaries. v Extended deep into the lithosphere FAULT Breaks in Earth s crust where rocks have slipped past each other.
7 What are the three types of boundaries? Divergent Boundaries Convergent Boundaries Transform Boundaries
8 Divergent Boundaries A plate boundary where two plates move away from each other.! " RIFTING causes SEAFLOOR SPREADING
9 How is the rock pulled at Divergent Boundaries? Rock gets THIN in the middle as it is pulled apart. This STRESS is called
10 What happens when the rock SNAPS from the Stress of Tension? A Normal Fault (fault is a break in Earth s crust) Rock drops down as it breaks
11 What happens next at Divergent Boundaries? A geologic feature or event May form RIFT VALLEYS on con:nents SEA- FLOOR SPREADING in the ocean
12 Helpful Hints Divergent is like dissec:ng or dividing If you pull warm bubble gum or silly puty, it will thin in the middle un:l it is stressed so much that it breaks. Happens on land & under H2O
13 Features of Divergent Boundaries Mid- ocean ridges riw valleys fissure volcanoes
14 How is the rock pushed at convergent boundaries? A plate boundary where two plates move towards each other. Boundaries between two plates that are colliding "! This stress is called COMPRESSION
15 Convergent Boundaries Places where plates crash (or crunch) together or subduct (one sinks under)
16 There are 3 types of Convergent Boundaries Ocean plate colliding with a less dense con;nental plate Subduc;on Zone: The process by which oceanic crust sinks beneath a deep- ocean trench and back into the mantle at a convergent plate boundary.
17 There are 3 types of Convergent Boundaries
18 What else happens at Convergent Boundaries? VOLCANOES occur at subduc;on zones h]ps:// be.com/ watch? v=if4tcxqpk ne
19 Andes Mountains, South America
20 Ocean plate colliding with another ocean plate The less dense plate slides under the more dense plate crea;ng a subduc;on zone called a TRENCH
21 Aleu:an Islands, Alaska
22 A con;nental plate colliding with another con;nental plate Have Collision Zones: A place where folded and thrust faulted mountains form.
23 May form Mountain Ranges. These are Folded Mountains, like the Himalayas or the Rockies.
24 What happens when the rock is squeezed from the Stress of Compression? A REVERSE FAULT Rock is forced upward as it is squeezed.
25 Helpful Hints Convergent = Connec:ng boundaries May work like a trash compactor smashing rock. Rock goes crunches up to make folded mountains. Rock goes down subduc:on zone.
26 Transform Boundaries A plate boundary where two plates move past each other in opposite direc;on.
27 How is the rock broken at Transform Boundaries? Rock is pushed in two opposite direc;ons (or sideways, but no rock is lost) This stress is called SHEARING
28 What happens next at Transform Boundaries? May cause Earthquakes when the rock snaps from the pressure. A famous a Transform Boundary is the San Andreas Fault in California.
29 San Andreas Fault, CA
30 What happens when the rock is sheared (or cut ) from the Stress of Shearing? A STRIKE- SLIP FAULT Rocks on each side of the fault slip past each other as they break.
31 Helpful Hints Shearing means cu_ng ( Shears are like scissors) Transform boundaries run like trains going past each other in different direc:ons & they shake the ground!
32 Plate Boundaries: Can you match the boundary name correctly with its diagram? A. B. C.
33 Plate Boundaries: Correct Answers: A. Divergent B. Convergent C. Transform
