Question

1. why do we find volcanoes near active tectonic zones?

Explanation:

Active tectonic zones (like plate boundaries) involve plate interactions. At convergent boundaries, one plate subducts (goes under another), melting the subducted plate and surrounding rock. This molten material (magma) rises, forming volcanoes. At divergent boundaries (like mid - ocean ridges) or transform - boundary - related rifts, the crust thins, allowing magma from the mantle to rise and create volcanoes. The movement and interaction of tectonic plates create the necessary conditions (pressure release, melting of rock) for magma to reach the surface and form volcanoes.

Answer:

Volcanoes are found near active tectonic zones because tectonic plate interactions (subduction at convergent boundaries, crust thinning at divergent boundaries) cause rock melting (forming magma) that rises to the surface, creating volcanoes. At convergent zones, subducted plates melt, and magma ascends. At divergent zones (e.g., mid - ocean ridges) or rifts, mantle magma rises as the crust thins.
