Question

a river carries sediment downstream and deposits it in a delta. over time, the sediment builds up in layers. which process in the rock cycle is taking place? a metamorphism of rock b deposition of sediment c melting of rock d crystallization of magma

Explanation:

The text describes a river carrying sediment and depositing it in a delta, building up layers over time. This directly corresponds to sediment deposition in the rock - cycle. Metamorphism involves changes in rock due to heat and pressure, melting is the change of rock to magma, and crystallization of magma forms igneous rocks. None of these other processes are described.

Answer:

B. Deposition of sediment
