What natural hazards can occur on a Destructive plate boundary?

Earthquakes and Volcanic eruptions

Flow diagram for how Destructive plate boundaries cause volcanoes to erupt

Flow diagram:

Plates move towards each other —> (which causes) the Oceanic plate subducting under the Continental plate —> (since it’s) denser. Oceanic plate melts in the mantle —> (which means that) it gets hotter —> (so) the plate melts into mantle. Magma is then stores into magma chambers —> (which makes) pressure build up. The magma then rises to the surface —> (so it causes) violent volcanoes to erupt, which are also known as composite volcanoes.

Flow diagram for how Destructive plate boundaries cause earthquakes

Flow diagram:

The Oceanic plate and Continental plate snag as they try to move past —> (which) builds up tension. When this tension is released, —> (this causes) violent earthquakes

What natural hazards can occur on a Constructive plate boundary?

Flow diagram for how Constructive boundaries cause volcanoes

Oceanic plates move away from each other —> (and this happens because) of convection currents and ridge push. —> (Because they are further apart), a gap has been created —> (which forms) volcanoes at surface —> (which are) called shield volcanoes —> (that are) gentle.

Flow diagram of how Constructive plate boundaries cause earthquakes

Oceanic plates move apart —> (because) of the rocks cracking and fracturing against each other —> (which releases) tension —> (and causes) small earthquakes.
