The focus question for this chapter of the book was
How does population density affect the way people live?
I’d like you to answer this question giving 4 examples from yesterday’s activity to support your answer.Think back to our examples from transportation, housing, land use and health careYou can just use bullet points

Plate tectonics=The Earth's surface is made up of moving plates
According to this theory, the Earth's crust….. is made up of about a dozen plates, some are little
and others take up 25% of the Earth’s surface is continually shifting because the surface beneath
them - the hot, soft mantle - is moving slowly like a conveyor belt, driven by heat and other forces at work in the Earth's core
is moving about a centimeter (0.5 in) to 15 centimeters (6 in) per year in different directions

Scientists believe that 200 million years ago there was one big megacontinent (Pangaea)
This broke up about 100 million years ago and made 2 continents (Gondwanaland and Laurasia) that were surrounded by the Panthalassa Ocean

This is where new crust to the Earth is formed with the plates split away from each other
This takes place underneath the ocean floor (called the Mid Atlantic Ridge)
You can see the Mid Atlantic Ridge in Iceland…that’s where it pops up to the surface!

This is where plates are destroyed when one plate dives under anotherOcean plates sink down
under continental ones because they are heavier
An example of this is the plate boundary by Japan

Any place on a planet where material from the inside of the planet makes its way through to the surface
The material the definition is referring to is magma (fluid molten rock), which ispartially liquid, partially solid and partially gaseous

Tsunamis can happen when underwater earthquakes happen
They happen at convergent boundaries, where ocean plates sink under land plates
When the plates underwater move, the water mirrors the change

Here’s a video of what happened in Japan in March 2011

Answer the questions on your worksheet using the website I’m about to project on the screen.
Connect the dots between Japan’s population, Japan’s landforms and the tsunami damage, both to people and to buildings….

When two continental plates collide at a convergent boundary, they both weigh the same
They crash into each other and create mountains
This is how the Himalayas (29,000 feet tall) got here

This is where the plates don’t get destroyed….they just slide next to each other

There are two ways you can apply plate tectonics to this clip from Finding Nemo….can you figure them out?
