Hotspots Flashcards
Which force is the strongest
The fastest rate of plate motion is at subduction zones. Might suggest slap pull is the strongest force. Convection alone is a weak force
Where are hotspots mainly found
Along divergent plate boundary
The pacific plate has a cluster of hot spots
Europe does not have any hot spots besides Iceland
African plate also has a cluster of hotspots
How do island clusters form
Hotspots do not move
Forms land
Land will move
Land breaks due to erosion
How do volcanic islands form (detail)
Volcanic hot spots are created as plumes of magma rise through the earths mantle
Heat from the core is passed to the mantle by conduction and heated portions of the lower mantle become less dense and buoyant and rise as diapirs
Why are hot spots created?
The lithosphere thinning or oceanic plate subduction
