Plate Tectonics

Large pieces of the Earth's lithosphere that move and change shape are called ________________. There are several major ones and nearly a dozen minor ones.

• Crustal fragments

• Volcanic Islands

• Continents

• Tectonic Plates

Scientists were able to use seismometers to help determine where the "edges" of tectonic plates were located. What did seismometers detect?

• Ground shaking from earthquakes

• The depth of ocean water

• The locations of glaciers

• How many fossils were found in rock layers

What layer is this?

(Hint: it's what the tectonic plates slowly move across...and it is solid, but kind of like "modeling clay")

• Oceanic Crust

• Continental Crust

• Upper Mantle

• Asthenosphere
