Plate Tectonics: Our Restless Planet guides students as they explore how plate
tectonics constantly reshapes our planet’s surface. Students learn that Earth’s
crust is broken up into large plates that move about on the mantle, the layer
beneath the crust. They read about how geologists analyzed many clues
to confirm the theory of plate tectonics. And they learn about the driving
force behind plate tectonics—convection currents in Earth’s partly liquid
mantle. Students also learn about the three types of plate boundaries and
the landforms that can result at these boundaries. Students discover how
earthquakes and volcanoes are related to plate tectonics. At the end of each
two-page spread, a brief statement called The Bottom Line reinforces students’
understanding by summing up the key ideas about plate tectonics covered in
those pages.
