Which phenomenon affects coastal regions during the cyclical subduction of the Juan de Fuca plate?

💡 Explanation

During subduction, the Juan de Fuca plate's movement is not constant; sometimes it sticks, leading to stress buildup and subsequent episodic tremor and slip events because of fault reactivation. Therefore ETSEs result, rather than thermohaline changes, increased orographic effects or weathering, which depend on ocean currents, altitude and rainfall, respectively.

• Which outcome occurs when tectonic stress exceeds bedrock strength?
• Which factor most directly elevates the likelihood of explosive volcanism along subduction zones?
• Which outcome is most likely downstream when unusually strong Benguela upwelling occurs off Namibia?
• Which consequence results when tephra deposition on glaciers accelerates melting?
• Which effect arises when the Coriolis force deflects atmospheric pressure gradients near the poles?
• Which long-term outcome occurs when fractured basalt bedrock weathers chemically in a cold, humid environment?
