Unraveling Divergent Plate Boundaries and Their Geological Impact

The video explains divergent plate boundaries, where tectonic plates move apart due to rising convection currents. This movement creates new crust as magma fills the gap. There are two main types: oceanic and continental divergent boundaries. Oceanic boundaries, like the Mid-Ocean Ridge, involve seafloor spreading, while continental boundaries, such as the East African Rift Valley, involve the separation of continental plates. The video also highlights examples like the Red Sea, formed by the divergence of the African and Arabian plates.

What occurs at divergent plate boundaries?

• Tectonic plates move towards each other

• Tectonic plates move away from each other

• Tectonic plates slide past each other

• Tectonic plates remain stationary

What is the primary cause of the movement of tectonic plates at divergent boundaries?

• Rising convection currents

• Earthquakes

• Tsunamis

• Volcanic eruptions

What is formed as a result of divergent boundaries?

• Earthquakes

• Volcanoes

• New crust

• Mountains

What is the role of magma in the formation of new crust at divergent boundaries?

• It erodes existing crust

• It fills the gap between separating plates

• It causes earthquakes

• It forms mountains

Which of the following is a common example of oceanic divergent boundaries?

• The Himalayas

• The San Andreas Fault

• The Great Barrier Reef

• The Mid-Atlantic Ridge

What process occurs at oceanic divergent boundaries?

• Mountain building

• Seafloor spreading

• Subduction

• Volcanic eruption

Which type of lithosphere is involved in oceanic divergent boundaries?

• Neither continental nor oceanic lithosphere

• Both continental and oceanic lithosphere

• Oceanic lithosphere

• Continental lithosphere

Which of the following is an example of a continental divergent boundary?

• The Rocky Mountains

• The Mariana Trench

• The East African Rift Valley

• The Andes Mountains

What geological feature was formed by the divergence between the African and Arabian plates?

• The Red Sea

• The Pacific Ocean

• The Himalayas

• The Great Rift Valley

What happens to the Red Sea as it transitions from a continental to an oceanic boundary?

• It becomes narrower

• It becomes wider

• It remains the same

• It disappears
