#### Transcript of Day 116 - Plate Tectonics (Notes)

BONUS WARM UP:
What kinds of science went into developing this concept phone? If you wanted to become a cell phone designer, what kinds of classes would you need to take in college?>
There are currently 8 major tectonic plates:
These plates are either moving TOWARDS or AWAY from each other.
Divergent Plate Boundaries

-SEAFLOOR SPREADING: The gap between the two plates exposes the Earth's mantle. This causes magma to push upwards and onto the Earth's surface. This occurs at MID OCEAN RIDGES.

-Most NEW crust is created here.

Divergent Plate Boundaries
Convergent Plate Boundaries
= two plates come together or collide.
When two plates collide, the denser of the two is pushed down, into the mantle. This is called SUBDUCTION. The plate being pushed down is being SUBDUCTED.
This produces MOUNTAINS and TRENCHES.
Convergent Plate Boundaries
Most mountain ranges found on land are a result of converging plates.
Transform Plate Boundaries
= when two plates rub in parallel and opposite directions to each other.
-Transform boundaries form FAULTS.

-Cities and towns located near faults experience many more earthquakes on average than those that are not.
Transform Boundaries
San Andreas Fault, North America
Alpine Fault, New Zealand

Cool Down:
1) Explain the difference between a hypothesis, a theory, and a law (in the field of science).
2) How is a scientific theory different than how people use the word theory in everyday life?

1. When scientists talk about the "ring of fire" what do you think they are referring to?
2. Why do you think Florida doesn't experience many Earthquakes?
3. How do scientists know about the super-continent Pangaea?

Brainteaser:
This is an unusual paragraph. I'm curious as to just how quickly you can find out what is so unusual about it. It looks so ordinary and plain that you would think nothing was wrong with it. In fact, nothing is wrong with it! It is highly unusual though. Study it and think about it, but you still may not find anything odd. But if you work at it a bit, you might find out.
