Volcanoes are formed at divergent and converging boundaries.

Answer;

Volcanoes

Volcanoes are formed at divergent and converging boundaries.

Explanation;Volcanoes are formed when tectonic plates are pushed together or pulled apart. The spread of the these tectonic plates causes hot magma, to rise up and fill the space between them.Thus, volcanoes result from the melting of the mantle, to form magma which moves to the surface of the crust, and volcanoes erupt. High temperatures and pressures in the mantle causes melting of rocks forming magma which rises through rock layers towards the surface of the Earth.
