180 Million Years Old


• RED SLIDE: These are notes that are very important and should be recorded in your science journal.

Copyright © 2010 Ryan P. Murphy

-Nice neat notes that are legible and use indentations when appropriate.

-Example of indent.

-Skip a line between topics -Don’t skip pages

-Make visuals clear and well drawn.

• RED SLIDE: These are notes that are very important and should be recorded in your science journal.

• BLACK SLIDE: Pay attention, follow directions, complete projects as described and answer required questions neatly.

• Dynamic Earth Available sheets that follow Part I for classwork if needed.

• Activity! Please make a puzzle from a magazine page. Puzzle should be no more than 15 large pieces.

• Solve yourself and then switch puzzles with you neighbor.

• Question to answer on next slide.

• Questions– What strategies did you use to complete the

puzzle? 3-5 sentences please.


Question? Look at the map below, do see any puzzle pieces, if so were would they fit?


Possible Answers!


Area of Focus: Plate Tectonics


Plate tectonics: The earth’s crust and upper mantle are broken into sections called plates. -


Plate tectonics: The earth’s crust and upper mantle are broken into sections called plates. These plates float on the mantle like

rafts (moving very slowly)


• There are 8 primary plates and several more secondary plates that make up the earth’s landmass.

• African Plate, Antarctic Plate, Australian Plate, Eurasian Plate, Indian Plate, North American Plate, Pacific Plate, South American Plate.

• The speed at which the plates move is about the speed at which your fingernails grow.




SlowestThey are all slow



SlowestThey are all slow

The African Plate's speed is estimated at around

2.15 cm (0.85 in) per year



Fastest



FastestTonga Microplate Samoa 24 cm (9.4 inches) a year.



The yearly distance traveled varies from plate to plate. Some move at 3 centimeters while other's move around 6 cm per year.

FastestTonga Microplate Samoa 24 cm (9.4 inches) a year.

• Activity! Everyone slide in your chair two feet southwest from your current location. (N. American Plate)

The Big Idea that plate tectonics most deals with is…

Plate tectonics is the driving force in Geology. It is a very BIG Concept

and plays a major role in everything we will study in this unit.

It causes…

Continental Drift: The gradual movement of the continents across the earth.

“I say.” “Africa and South America fit strangely like

two puzzle pieces.”

Coolest new word of the day coming up…

The theory that all geologic phenomena may be explained as the result of existing forces having operated uniformly from the origin of the earth to the present time.Gravity, Erosion, Chemical Reactions, and more happen today the same as they did billions of years. Some things don’t change.

• The magnetic poles can shift “fairly” suddenly on this planet. – Right now, North is in the Arctic, the North

Pole could shift to someplace else.


• Iron within cooling molten rock orients itself to the poles before hardening.


• Iron within cooling molten rock orients itself to the poles before hardening. – The ocean floor shows evidence of a changing

magnetic field, and sea-floor spreading.

• Note how the oceanic plates are much older the further they are from the mid-Atlantic ridge.

Next Slide

• 800 million years before Pangea, the continents were together in the supercontinent Rodinia.

• Climatic changes created a snowball earth where the entire planet was covered in a mile thick of ice.

• Climatic changes created a snowball earth where the entire planet was covered in a mile thick of ice. (Mass extinction of ocean life)

• Behold the Supercontinent! Pangea

Applause!



End Applause!

Pangea: The “Supercontinent” -


Pangea: The “Supercontinent” All of the plates were once together.


The Big Idea about Rodinia and Pangea is…

The Earth is 4.6 Billion Years Old

Supercontinent Rodinia was 800 Million Years Ago

The position of the continents have also changed.

Gondwondaland and Laurasia were two mega continents before Pangea.


• Activity! Recreating Pangea with cutouts of the continental plates.– Can you cut-out the continents in one cut?

• Activity! Recreating Pangea with cutouts of the continental plates (Sheet Provided)

• Activity! Recreating Pangea with cutouts of the continental plates (Sheet Provided)– Please use the animation on the next slide to

practice creating Pangea and then moving the continents to their current location.

– Then go back to Pangea and back to current day until you can do it without the animation.
