Please help... This is middle school stuff. It'll be easy for you.

Volcano eruptions-when one plate is submerged below another, it melts and goes back to the surface as magma and creates a volcano

Earthquakes- when 2 plates slide against or hit each other

Seafloor spreading- where divergent plates move away from esch other, magma goes up to the surface and solidifies

Mountain formation- When two convergent continental plates hit each other. Continental plates are light so instead of submerging, they both rise higher to the surface and creates high land(mountains)

HOPE THIS HELPS
