Which consequence results when significant tephra deposition overtops drainage divides?

💡 Explanation

Temporary stream redirection occurs because tephra deposition disrupts existing drainage patterns via channel blockage creating new, often unstable stream paths via the mechanism of avulsion; therefore, new networks form, rather than changing glacial mass balance because the effect focuses on surface hydrology.
