Which events are associated with convergent boundaries? check all that apply. formation of island chains creation of mid-ocean ridges creation of new mountains formation of earthquakes formation of volcanoes

Creation of mid-ocean ridges, creation of new mountains, formation of earthquakes, and formation of volcanoes.

Explanation:

The convergent boundary plate tectonic comprises collisions between the continental and oceanic plates. The less dense and thinner oceanic plate gets overridden by the more denser and thicker continental plate. The ocean plate is forced down the mantle, and the event is called subduction.  

The magma found in the mantle leads to melting of the subduction plates. The magma gets within the plates via pores. This magma plate turns buoyant and moves in an upward direction. The molten magma leads to volcanic eruptions along with earthquakes. The solidification of magma in the subduction zone leads to the formation of ocean ridges. The formation of mountains close to the continents takes place when the magma after the volcanic eruption gets cooled and solidifies.  

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
