Which geological impact results from extensive tephra deposition?

💡 Explanation

Decreased infiltration stems from tephra blocking soil pores due to particle INFTRATION BLOCKAGE; therefore, groundwater reservoirs deplete because surface water isn't replenished, rather than direct contamination or radiation changes, which require different components.
