Plate Tectonics

This is the theory that Earth's outer layer is made up of large, moving pieces called plates. All of Earth's land and water sit on these plates. The plates are made of solid rock. Under the plates is a weaker layer of partially melted rock. The plates are constantly moving over this weaker layer.

Slow Drifting

We're all slow drifting on the Earth's tectonic plates.

If we drift too far we're gonna lose some coastal states.

When they rub together they make the earth rumble and shake

'cause we're all slow drifting on the Earth's tectonic plates

Convergent boundaries occur when plates crash together

They form mountain ranges where we can ski in cold weather

This collision forces one plate into the earth

Where the Plates rocks are melted and prepared for rebirth

Divergent Boundaries are caused when plates pull apart

The space between them is where an earthen rift starts

Magma seeps up on through the remaining cracks

And forms new crust so the earth's surface never lacks

Plate Tectonics Comprehensive Diagram Project

Use Google Drawing to create a diagram and flowchart that demonstrates the answer to the question, "How does the Theory of Plate Tectonics support the Theories of Continental Drift and Sea Floor Spreading?"

In doing this activity you will develop a model to describe unobservable mechanisms.

Success Criteria

A complete diagram includes

• a labeled diagram that depicts the essential parts of the earth
• full support of the Theory of Continental Drift and Sea Floor Spreading.

Day 1

Before you begin...

• What are the essential elements of any scientific diagram?
• What elements should be required in a complete diagram of the Theory of Plate Tectonics?

Day 2

Success Criteria

• I have worked with my group to create a labeled diagram that depicts the essential parts of the earth.
• I can use my diagram to demonstrate my understanding of The Theory of Plate Tectonics.

Mid-Work Conference (5 Minutes)

• Evaluate your progress and determine whether you are on target to meet your goal or not.
  1. What do you still need to get done in order to be successful?
  2. How will you be able to use your diagram to demonstrate an understanding of The Theory of Plate Tectonics?
