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 topographic consequence results from the subduction of an oceanic plate beneath a continental plate lacking sufficient sediment?
• Which mechanism drives the formation of desert regions under subtropical high-pressure zones?
• Which consequence results when katabatic winds encounter a strong temperature inversion near a valley floor?
• Which consequence occurs when prolonged river sedimentation exceeds levee subsidence in a delta?
• Which effect does the Coriolis force have on warm ocean currents moving poleward from the equator?
• Which consequence results when tephra accumulation exceeds capacity?
