Which mechanism initiates the formation of rift valleys along divergent continental plate boundaries?

💡 Explanation

When continental plates diverge, tensional stress increases causing crustal extension because lithospheric thinning occurs, resulting in normal faulting and subsidence. Therefore rift valley formation results, rather than folding, strike-slip faulting or hydrothermal alteration which require different stress regimes.
