Plate Tectonics and Earth's Dynamic Crust

The video discusses plate tectonics, explaining how Earth's crust is divided into moving plates. It covers the concept of Pangaea and the role of convection currents in the mantle that drive plate movement. The video also describes the three types of plate boundaries: convergent, divergent, and transform, highlighting their characteristics and effects, such as earthquakes and volcanic activity. The video concludes with a summary and encourages viewer interaction.

What is the Earth's crust primarily composed of?

• Molten lava

• Solid rock

• Water

• Moving plates

What is the main force that causes the movement of tectonic plates?

• Wind

• Convection currents

• Gravity

• Magnetic fields

What is the process called where the mantle heats and cools, driving plate movement?

• Subduction

• Convection

• Sedimentation

What occurs at a convergent boundary?

• Plates remain stationary

• Plates collide

• Plates slide past each other

• Plates move apart

What geological feature can form as a result of subduction at convergent boundaries?

• Rivers

• Volcanoes

• Deserts

• Mountains

What happens at divergent boundaries?

• Plates slide past each other

• Plates collide

• Plates move apart

• Plates remain stationary

What is created when magma rises at divergent boundaries?

• Earthquakes

• New crust

• Volcanoes

• Mountains

What is the primary result of transform boundaries?
