What outcome significantly diminishes agricultural yields after a large eruption?

💡 Explanation

Stratospheric aerosol injection leads to decreased solar radiation because the mechanism is global dimming; therefore, crop yields fall over large distances rather than being confined through other local volcanic hazards.

• Which outcome results from floodplain silt deposition inhibiting drainage?
• Which mechanism causes a meandering stream to erode one bank while depositing sediment on the opposite bank?
• Which process establishes distinct stratification layers within a dimictic lake?
• Which process explains pyroclastic flow formation during Plinian volcanic eruptions?
• Which mechanism causes increased coastal subsidence during an earthquake along a subduction zone lacking sediment?
• Which effect occurs when multiple ocean gyres become more stratified due to freshwater input from melting glaciers?
