LAYERS OF THE EARTH

• The Earth can be divided into layers based on physical properties—the lithosphere, asthenosphere, outer core, and inner core

Page 9: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

THE LITHOSPHERE

• Earth’s outermost layer of the crust and uppermost mantle and forms a relatively cool rigid shell called the lithosphere.

Page 10: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

THE BEGINNING

• Most people thought that the continents had always been and would always be in the same place

Page 11: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

A PUZZLE?

• But some people noticed that the continents fit together somewhat like a jigsaw puzzle

LOOK AT THE WESTERN SIDE OF AFRICA AND THE EASTERN SIDE OF

SOUTH AMERICA

Page 14: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

IF YOU TURN SOUTH AMERICA, AND THEN SLIDE IT OVER

It fits right in….

Page 15: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

SOME EARLY IDEAS

• In 1858, an American, A. Snider published an article on the origin of the Americas

• He thought that South America and Africa were once together

• Snider proposed that a huge volcanic event caused the landmass to split

Page 16: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

HALF A CENTURY LATER… THIS IDEA CONTINUED AS CONTINENTAL DRIFT

• In 1910, an American, F.B. Taylor, discussed the origin of mountains

• He explained that continental movements that ended in collisions would cause the formation of mountains

Page 17: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

MORE SCIENTISTS JOINED IN…

• German scientist, Alfred Wegener published The Origin of Continents and Oceans

• He proposed that the continents had once been joined together in a supercontinent he called Pangaea

• The continents then pulled apart through a mechanism called continental drift

Page 18: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

WHAT’S IN A NAME?

• The word Pangea, or Pangaea, is Greek for “all land”

• Why do you think he chose this name for the supercontinent?

• What would you name it? Why?

Page 19: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

• Most of his colleagues didn’t agree with him

• He couldn’t explain why the continents did not seem to be moving now

• He couldn’t explain how such huge landmasses moved

Page 20: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

WEGENER’S EVIDENCE

• The same fossils were found in Africa and South America directly across the ocean from each other

• These species could not have crossed between the continents by swimming

Page 21: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

MORE EVIDENCE FINALLY CAME

• This idea of continental drift was not really excepted until the 1960’s

• Scientists found evidence that the sea floor was spreading

Page 22: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

SO…WHAT HAPPENED TO PANGAEA?

• About 200 million years ago Pangaea existed

• Dinosaurs roamed all over the land

Tethys Sea

Page 23: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

• About 180 million years ago, rifting along an ancient body of water called Tethys Sea broke the supercontinent into a northern land mass called Laurasia and a southern land mass called Gondwanaland

Tethys Sea

Page 24: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

MORE SPLITTING…

• Then plate movements split Laurasia into North America, Europe, and Asia

• And Gondwanaland split into South America, Africa, peninsular India and later Australia and Antarctica

• This also formed the Atlantic Ocean

Page 25: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

PLATE TECTONIC THEORY

• Not as simple as core, mantle, & crust• Remember, there is a

• A solid inner core composed mainly of iron alloy

• An outer core that is hot, liquid, iron• A solid mantle that is so hot that all but the

uppermost portion of it flows• An outer crust which is solid

Page 26: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

THE BROKEN PIECES OF THE LITHOSPHERE

The lithosphere is divided into several very large plates which can be divided into smaller plates

Page 27: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

BOUNDARIES – WHERE THE PLATES MEET

• Divergent, Mid-Atlantic Ridge • Convergent, mountain building

• Subduction Zones

• Transform FaultsSan Andreas Fault, lots of earthquakes

GALLERY WALK

• Use your graphic organizer to take notes at each station.

Page 30: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

DIVERGENT BOUNDARIES

•Boundary between two plates that are moving apart or rifting

•RIFTING causes SEAFLOOR SPREADING

Page 31: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

DIVERGENT BOUNDARIES

•Two Types: •1. Oceanic Ridges and Seafloor Spreading

•2. Continental Rifts

Page 32: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

OCEANIC RIDGES AND SEAFLOOR SPREADING•Seafloor spreading is the process by which plate tectonics produces new oceanic lithosphere

•Example: East African Rift valleys

Page 33: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

CONTINENTAL RIFTS•When spreading centers develop within a continent, the landmass may split into two or more smaller segments

•Examples: Mount Kilimanjaro,Mount Kenya

Page 34: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

TRANSFORM FAULT BOUNDARIES

•Boundary between two plates that are sliding past each other

•EARTHQUAKES along faults•Ex. San Andreas Fault, California

Page 35: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere
Page 36: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

CONVERGENT BOUNDARIES

•Boundaries between two plates that are colliding

•Three types:

•1. Oceanic-Continental•2. Oceanic-Oceanic•3. Continental-Continental

Page 37: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

OCEANIC-CONTINENTAL•Ocean plate colliding with a less dense continental plate

•Subduction Zone: where the less dense plate slides under the more dense plate

•VOLCANOES occur at subduction zones

•Example: Volcanoes of the Andes

Page 38: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere
Page 39: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

OCEANIC-OCEANIC•Ocean plate colliding with another ocean plate

•The less dense plate slides under the more dense plate creating a subduction zone called a TRENCH

•Example: The Aleutian Islands off the shore of Alaska

Page 40: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere
Page 41: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

CONTINENTAL-CONTINENTAL

•A continental plate colliding with another continental plate

•Have Collision Zones:•a place where folded and thrust faulted mountains form.

•Example: India ramming into Asia, producing the Himalayas

Page 44: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

TRANSFORM FAULT BOUNDARIES

•Boundary between two plates that are sliding past each other

•EARTHQUAKES along faults•Ex. San Andreas Fault, California

Page 45: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere
Page 46: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

CAUSES OF PLATE TECTONICS

•Mantle convection •Ridge push•Slab pull

Page 47: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

MANTLE CONVECTION CURRENTS

•Hot magma in the Earth moves toward the surface, cools, then sinks again.

•Creates convection currents beneath the plates that cause the plates to move.

Page 48: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

RIDGE PUSH

•The oceanic lithosphere slides down the sides of the oceanic ridge

•The downward slide is a result of gravity

Page 49: DO NOW Journal Prompt:. YET OBJECTIVE SWBAT explain how plate tectonics impacts the lithosphere

SLAB PULL

•Old oceanic crust, which is cool & dense, sinks into the asthenosphere and “pulls” the rest of the lithosphere down with it
