Plate Tectonics Video

What are the two main ways scientists categorize the Earth's layers?

• By density and temperature

• By chemical composition and mechanical properties

• By solid and liquid states

• By inner and outer regions

Which layer of the Earth is described as being somewhat fluid due to increased pressure and heat, allowing it to move like heated rock?

• Lithosphere

• Mesosphere

• Asthenosphere

• Inner core

Which scientist proposed the theory that all continents were once joined together in a single supercontinent called Pangaea?

• Charles Darwin

• Isaac Newton

• Alfred Wegener

• Marie Curie

Which of the following provided evidence supporting the idea of continental movement and the Plate Tectonics Theory?

• The consistent global climate over millions of years.

• The discovery of heated magma rising through cracks in the oceanic crust.

• The unchanging positions of mountains and oceans.

• The uniform distribution of all fossil types across continents.

The modern-day Plate Tectonics Theory is based on concepts first proposed by which scientist?

• Charles Darwin

• Isaac Newton

• Alfred Wegener

• Albert Einstein

What geological feature is formed when one tectonic plate dives under another at a convergent boundary?

• A rift valley

• A fault line

• A subduction zone

• A mid-ocean ridge

What geological event is primarily associated with transform boundaries where plates slide past each other?

• Volcanic eruptions

• Mountain formation

• Earthquakes

• Seafloor spreading

What process occurs at divergent boundaries located under the ocean where magma rises to fill the space between separating plates?

• Subduction

• Seafloor spreading

• Mountain building

• Faulting
