Plate Tectonics

Plate Tectonics

8.9A - The student is expected to describe the historical development of evidence that supports plate tectonic theory.

Objectives:

• Content Objective: Rockets will complete a fold-able so they can explain plate tectonic theory.

• Language Objective: Rockets will listen to short explanations, write in their fold-able, and answer questions related to the theory of plate tectonics.

The earth moves!

Our earth moves! We have many pieces of evidence for this some we can even feel; like earthquakes. So what is causes the movement? Magma! Deep in the Earth, molten rock churns as it heats and cools in convection currents. This moves the crustlike plates on top, and even creates and new and destroys old plates. *VIDEO TIME*
