Divergent Boundaries and Hotspots in Earth's Geology

The video tutorial explains different types of plate boundaries: divergent, convergent, and transformed fault boundaries. It covers ocean-to-ocean and continental divergent boundaries, highlighting mid-ocean ridges and rift valleys. The tutorial also discusses continental-oceanic and continental-continental convergent boundaries, focusing on subduction and mountain formation. Additionally, it explains transformed fault boundaries and hotspots, with examples like the San Andreas Fault and Hawaiian islands.

What is created at ocean-to-ocean divergent boundaries?

• New oceanic lithosphere

• Mountain ranges

• Volcanic islands

• Deep ocean trenches

Where can continental-to-continental divergent boundaries be found?

• Rift valleys in northwestern Europe and east Africa

• Mid-ocean ridges

• The San Andreas Fault

• The Andes in South America

What happens to the oceanic lithosphere in a continental-to-oceanic convergent boundary?

• It floats on the surface

• It creates a hotspot

• It is subducted beneath the continental lithosphere

• It forms a rift valley

Which mountain range is formed by continental-to-continental convergent boundaries?

• The Rhine Valley

• The Andes

• The Hawaiian Islands

• The Himalayas

What is the primary movement in transformed fault boundaries?

• Divergent spreading

• Horizontal grinding

• Convergent collision

• Vertical subduction

Which fault is an example of a transformed fault boundary?

• The Andes

• The Great Rift Valley

• The San Andreas Fault

• The Swiss Alps

What causes the formation of hotspots?

• Divergent plate movement

• Subduction of oceanic lithosphere

• Continental collision

• Mantle plumes rising to the surface

Which islands are an example of a hotspot?

• The Hawaiian Islands

• The Canary Islands

• The Galapagos Islands

• The British Isles

What is the result when magma from a hotspot reaches the surface?

• A rift valley is formed

• A volcanic region is created

• A mountain range is uplifted

• A deep ocean trench is formed

How long have most hotspots been active?

• A few years

• A few centuries

• A few decades

• Millions of years
