Convection Currents in the Mantle

1. Preview pages 14-17 in text.
2. Review Google Presentation below on Convection Currents. Create an outline as you view the presentation. You may need to use your book to continue with the outline.
3. Visit website link on the last page of the google presentation and complete both quizzes on website after reading material.
4. View movie.
5. Answer questions related to Convection currents below in your google document.

How is heat transferred?
What causes convection currents?
What causes convection currents in Earth’s mantle?
