plate boundaries

Question 1

what happens at divergent plate boundaries

Answer 1

plates move apart-magma rises through the gap in the earths crust and forms shield volcanoes- 2 oceanic plates

Question 2

what is a destructive/convergent plate boundary

Answer 2

an oceanic and continental plate moving towards each other - when met the oceanic plate subducts under the continental plate- causes composite volcanoes , tsunamis and earthquakes

Question 3

what happens at collision plate boundaries

Answer 3

2 continential plate boundaries move towards eachother - causes fold mountains e.g himilayas and mount everest

Question 4

what happens at a conservative plate boundary

Answer 4

plates moving alongside each other at different speeds or in opposite directions- when the plates are stuck or dislodge this causes an earthquake

Question 5

which is denser oceanic plates or continetal

Answer 5

oceanic

Question 6

what is the hotspot theory

Answer 6

fixed spots in the mantle where magma rises to the surface. As the crust moves over these fixed spots, volcanoes are created, eventually forming a chain of volcanoes.
