What will happen at a divergent (constructive) plate boundry?
Sheild volcano and earthquakes
What will happen at a convergent (destructive) plate boundry?
Cone/composite volcano
Earthquakes
What will happen at a conservative (transform) plate boundry?
Earthquakes
What will happen at a convergent (collision) boundry?
Fold mountain
Earthquakes
Examples of plates at divergent?
North american plate and Eurasian plate are slowly moving away from eachother
Features produced from divergent
Sea flooor spreading at divergent (constructive) plate boundry
Continental crust
Creates new land
Earthquakes and volcanoes
Example area of divergent ?
North america, south america and africa
Conservative examples of plates?
North american plate and pacific plate are moving away from each other
Features produced from conservative?
Pressure release causes violent earthquakes
Collision example of plates
Plates colliding into each other e.g eurasian plate and indian plate
Features produced from collision
Fold mountains, mountains, himilayas
