Divergent Plate Boundaries

What happens at divergent plate boundaries?

• Plates move towards each other

• No significant movement occurs

• Plates move away from each other

• Plates slide past each other

What is the lithosphere made of?

• Only the Earth's crust

• Only the solid part of the mantle

• The Earth's crust and the solid part of the mantle

• The Earth's crust and the entire mantle

How do hot spots form according to the video?

• Due to the movement of tectonic plates

• By convection currents in the mantle

• All of the above

• Through mantle plumes at the core-mantle boundary

What causes the crust to start cracking at a divergent boundary?

• Cooling of the magma

• Pressure from below by hot magma

• Gravitational forces

• Erosion by water

What analogy is used to explain the process of rift formation?

• A loaf of bread baking

• Ice cracking

• A glass breaking

• A balloon expanding

What is a rift valley?

• A valley formed by the erosion of water

• A valley formed by the convergence of tectonic plates

• A valley formed by the movement of glaciers

• A valley formed by the divergence of tectonic plates

What is the African Rift Valley an example of?

• A transform plate boundary

• A divergent plate boundary

• A convergent plate boundary

• A subduction zone

How does the Red Sea relate to plate tectonics?

• It has no relation to plate tectonics

• It is a result of a divergent boundary

• It is a result of a transform boundary

• It is a result of a convergent boundary

What eventually forms from a hot spot causing a rift valley?

• A mountain range

• A plateau

• A deep ocean trench

• A mid-oceanic ridge

Why does uplifted land appear around a mid-oceanic ridge?

• Due to sediment deposition

• Because of gravitational pull

• Because of magma pushing the land upwards

• Due to erosion
