Plate Tectonics and Boundaries

The video tutorial covers the basics of plate tectonics, including the Earth's layers: crust, mantle, and core. It explains tectonic plates, their formation, and how they are visible on topographic maps. The tutorial details the three types of plate boundaries: convergent, divergent, and transform, highlighting their features and associated geological activities. Convection currents in the mantle are discussed as a driving force for plate movements, influencing whether plates converge or diverge. By the end, viewers should understand the characteristics of each plate boundary.

Which layer of the Earth is known for its flowing properties?

• Upper Mantle

• Crust

• Lower Mantle

• Inner Core

What constitutes a tectonic plate?

• Only mantle

• Crust and cooled mantle

• Core and mantle

• Only crust

Which type of plate boundary involves one plate moving under another?

• Convergent without subduction

• Convergent with subduction

• Transform

• Divergent

What geological features are commonly found at convergent boundaries?

• Deserts

• Flat plains

• Ridges

• Earthquakes and volcanoes

What is a key feature of divergent plate boundaries?

• Fault lines

• Trenches

• Mountain ranges

• Ridges

Which type of rock is typically formed at divergent boundaries?

• Metamorphic

• None

• Sedimentary

• Igneous

What is the main characteristic of transform boundaries?

• Mountains

• Volcanoes

• Ridges

• Earthquakes

Where are most transform boundaries located?

• In forests

• Above ground

• Underwater

• In deserts

What role do convection currents play in plate tectonics?

• They create new plates

• They move tectonic plates

• They destroy old plates

• They have no role

What happens when convection currents flow in opposite directions?

• Plates remain stationary

• Plates become transform

• Plates become divergent

• Plates become convergent
