Tectonic Plate Boundaries and Features

The video tutorial introduces basic vocabulary and concepts related to plate tectonics, including the lithosphere, asthenosphere, subduction, and seafloor spreading. It explains the movement of tectonic plates and the processes of subduction and seafloor spreading. The tutorial also covers different types of plate boundaries: divergent, convergent, and transform. Instructions for labeling diagrams and understanding geological features like volcanoes and mountains are provided. Finally, the formation of ocean basins through divergent boundaries is discussed.

What is the lithosphere primarily composed of?

• Molten metal

• Liquid magma

• Solid rock

• Gaseous elements

Which layer allows tectonic plates to move?

• Core

• Lithosphere

• Asthenosphere

What happens during subduction?

• Two plates collide and form mountains

• One plate sinks beneath another

• One plate slides past another
