Divergent Plate Boundaries and Geological Features

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, particularly in oceanic crusts. The tutorial also explores continental divergence, resulting in fault block mountains and rift valleys, with examples like the East African Rift.

What happens when two continental crusts converge?

• Formation of a Rift Valley

• Creation of fold mountains

• Subduction of one crust

• Formation of mid-ocean ridges

What is a fault line?

• A mountain range formed by convergence

• A deep ocean trench

• A type of volcanic eruption

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

Where are most divergent plate boundaries located?

• Along mountain ranges

• In the center of oceans

• At the edges of tectonic plates

• In the middle of continents

What geological feature is formed by seafloor spreading?

• Mid-ocean ridges

• Deep-sea trenches

• Fault block mountains

• Volcanic islands

What is the Mid-Atlantic Ridge an example of?

• A subduction zone

• A divergent boundary

• A transform fault

• A convergent boundary

What occurs when two continental crusts diverge?

• Formation of volcanic islands

• Creation of fault block mountains

• Subduction of one crust

• Formation of mid-ocean ridges

What is a Rift Valley?

• A deep ocean trench

• A valley formed by the divergence of tectonic plates

• A type of volcanic eruption

• A mountain range formed by convergence

What is the East African Rift an example of?

• A convergent boundary

• A transform fault

• A divergent boundary

• A subduction zone

What is the potential future outcome of the East African Rift?

• Subduction of the African plate

• Creation of a new mountain range

• Division of the African continent into two

• Formation of a new ocean

What are fault block mountains?

• Mountains formed by the subduction of oceanic plates

• Mountains formed by blocks of crust rising and sinking

• Mountains formed by volcanic activity

• Mountains formed by the folding of Earth's crust
