what is the corriolis effect

the spin of the earth

name 3 mitigation strategies for climate change

what happens at a constructive margin

two oceanic plates move apart from each other, when this happens magma from mantle rises to form a shield volcano. they can cause volcanoes and earthquakes

what happens at a conservative margin

the plates move past eachother or move side by side at different speeds, as they move past eachother the friction causes them to get stuck. they cause earthquakes

what happens at a destructive margin

the oceanic crust is forced to sink back into the mantle whilst the continental crust rises above forming volcanos and earthquakes

what happens at a collision margin

two continental plates collide, neither sink so they go through land and form fold mountains they can cause earthquakes
