Divergent Plate Boundaries Concepts

The video tutorial covers the continuation of lesson three on shaping Earth's surface, focusing on plate tectonics. It explains the types of convergence, including continental and oceanic crust interactions, leading to subduction and volcanic activities. The lesson then shifts to divergent plate boundaries, describing how they create fault lines and mid-ocean ridges, primarily in oceanic settings. The tutorial also explores the divergence of continental crusts, resulting in fault block mountains and rift valleys, with examples like the East African Rift.

What happens when two continental crusts converge?

• They result in volcanic islands.

• They create fold mountains.

• They cause seafloor spreading.

• They form a rift valley.

What is a fault line?

• A mountain range formed by convergence.

• A type of volcanic eruption.

• A deep ocean trench.

• A break in the Earth's crust due to plate movement.

Where are most divergent plate boundaries located?

• In the middle of continents.

• At the edges of tectonic plates.

• In the center of oceans.

• Along mountain ranges.

What geological feature is formed by seafloor spreading?

• Mid-ocean ridges

• Volcanic islands

• Fault block mountains

• Deep sea trenches

What is the Mid-Atlantic Ridge an example of?

• A transform fault

• A subduction zone

• A convergent boundary

• A divergent boundary

What occurs when two continental crusts diverge?

• Creation of fault block mountains

• Formation of volcanic islands

• Development of deep ocean trenches

• Emergence of mid-ocean ridges

What is a Rift Valley?

• A volcanic island chain

• A type of mountain range

• A valley formed by divergent plate movement

• A deep ocean trench

Which plates are involved in the East African Rift System?

• Pacific and North American plates

• Eurasian and Indian plates

• South American and African plates

• Nubian and Somalian plates

What is the expected outcome if the East African Rift continues to diverge?

• Emergence of a volcanic island

• Formation of a new ocean

• Creation of a mountain range

• Division of Africa into two continents

What is the primary cause of fault block mountains?

• Divergent plate boundaries

• Transform faults

• Subduction zones

• Convergent plate boundaries
