Which weathering cause accelerates the erosion of coastal sea stacks formed from sedimentary rock?

💡 Explanation

Hydraulic action accelerates sea stack erosion because pressurized water forces into bedding planes initiates fracturing, therefore differential erosion is increased, rather than solely chemical weathering; other processes are unrelated factors.

• Which risk increases when groundwater extraction reduces pore pressure near a fault line experiencing tectonic stress?
• Which long-term outcome results when hardened jetties interrupt longshore transport across a barrier island system?
• Which risk increases on gentle slopes underlain by permafrost undergoing active solifluction?
• Which mechanism dominates stream diversion across orogenic belts?
• Which risk increases when a rhyolitic lava dome nears collapse?
• Which coastal ecosystem consequence results from El Niño?
