Plate Tectonics and Geological Features

The video covers geological oceanography, focusing on plate tectonics, types of plate boundaries, and the mechanisms of plate movement. It explains the hotspot theory and predicts future plate movements. The video also discusses coastal formation and dynamics, including the classification of coasts and features like spits and tumolos.

Which type of plate boundary is associated with the creation of mountain ranges?

• Divergent

• Transform

• Convergent

• Static

What geological feature is formed when two oceanic plates converge?

• Mid-ocean ridges

• Trenches and island arcs

• Volcanic mountain ranges

• Fault lines

What is the primary concept behind plate tectonics?

• The Earth's atmosphere controls plate movement.

• The Earth's core is the only part that moves.

• The Earth's lithosphere is divided into moving plates.

• The Earth is a solid, immovable mass.

What happens at a divergent plate boundary?

• Crust is destroyed.

• Plates remain stationary.

• Crust is created.

• Plates slide past each other.

Which type of plate boundary is characterized by lateral sliding?

• Convergent

• Divergent

• Transform

• Subduction

What is the role of convection currents in plate tectonics?

• They keep the plates stationary.

• They cause the plates to move.

• They only affect the Earth's core.

• They are unrelated to plate movement.

What is a hotspot in geological terms?

• A location on Earth's surface with active volcanism.

• A region of intense earthquake activity.

• A place where oceanic crust is destroyed.

• A location where plates are stationary.

Which ocean is predicted to shrink in the future?

• Indian Ocean

• Atlantic Ocean

• Pacific Ocean

• Arctic Ocean

What is a primary coast formed by?

• Marine actions

• River erosion or deposition

• Wind erosion

• Human activities

What is a spit in coastal geography?

• A deep ocean trench.

• A type of coral reef.

• A length of sand attached to land at one end.

• A mountain range formed by tectonic activity.
