TECTONIC PLATE BOUNDARIES
OBSERVATIONAL MODEL LAB
Today you will choose one of the 3 plate boundaries to make a model.
CONTEST FOR BEST MODELS!!!!
Plate boundaries are where 2 tectonic plates meet on the surface of the earth

BOUNDARY MODEL
- Join my google classroom
- Code: 1gk3j5b
- This video and other links will be there.
- Today we will model tectonic plate movements and the landforms they create
- You will choose 1,2,3, or 4 to make your model and label
- If there is time, make one more
- Take photos with your chromebook
FIRST:
Join my google classroom class using your chromebook.
You will need to take and upload pictures when you submit your assignment. I will show you how.
I will put some of the good ones in our class dojo page

LABEL IT
Use toothpicks and cut up sticky notes to make your flag labels for your model
Only make the labels for the type of model you make. Don't make them all.

THE EARTH'S CRUST
Broken up into pieces called tectonic plates that are moving, slowly
There are seven major tectonic plates of the world. We live on the north American plate
TECTONIC PLATE BOUNDARIES
Where plates meet, the earth reacts
You need to recognize these three types of tectonic plate boundaries and
What type of land is created at each one.
What type of land is created at each one.
1. CONVERGENT BOUNDARY
TWO TECTONIC PLATES COLLIDING
The oceanic plate (Lithosphere) slides under (SUBDUCTS) the continental crust, recycling crust into the mantle 🔥🔥 and creating
OCEAN TRENCH, and VOLCANO

Volcano produced on land
Oceanic trench (deep valley) made under ocean off the coast

2. DIVERGENT BOUNDARY
Oceanic plate ⬅️➡️ oceanic plate
MID ATLANTIC RIDGE
At divergent boundary, length 10,000 miles
The underwater mountain range forms when to oceanic plates diverge and go opposite directions. New crust is created as magma fills in the empty space and creates a chain of mountains – the mid Atlantic Ridge
UNDER OCEANS ↘️🌊
⬅️ oceanic plate _^_ oceanic plate ➡️
each plate is a different color
A large flat OCEAN BASIN is created as plates pull apart.
An OCEAN RIDGE (mountain range) is formed as magma pushes up through the boundary and creates NEW CRUST

3. TRANFORM BOUNDARY

Plates sliding create friction and potential energy......then
EARTHQUAKES
Most earthquakes occur at plate boundaries
The most violent earthquakes on Earth occur at tectonic plate boundaries.

3. Transform boundary
POTENTAL ENERGY stores up as plates grind against each other due to stress and friction.
When the tension is released, an earthquake occurs.

FINISH YOUR STUDENT SHEET
- Make sure you can identify the 3 plate boundaries
- Identify the land formations that occur at the plate boundaries
- Take pictures of your models and add them to your google classroom; then submit
