What is the term for Alfred Wegener's theory that Earth's crust is divided into sections that move and interact with each other?

• Continental drift
• Plate tectonics
• Seafloor spreading
• Subduction zones

Which term describes the slow movement of hot, softened mantle that causes tectonic plates to move?

• Convection currents
• Volcanic eruption
• Seismic waves

What is the boundary called where two tectonic plates move away from each other?

• Transform boundary
• Convergent boundary
• Divergent boundary
• Subduction zone

The boundary where two tectonic plates collide is known as a:

• Transform boundary
• Convergent boundary
• Divergent boundary

The process where one tectonic plate moves beneath another is called:

• rifting
• spreading
• drifting
• subduction

The outer, rigid layer of Earth that includes the crust and uppermost mantle is called the:

• outer core
• inner core
• lithosphere
• crust

What type of boundary occurs when plates slide past each other horizontally?

• Transform boundary
• Convergent boundary
• Divergent boundary

The idea that all continents were once joined together in a single landmass is called

• plate movement
• continental drift
• oceanic drift
• Pangea

The newest theory that scientists have now accepted to explain how Earth's continents move is called:
