Which outcome is caused on a volcanic lahar's energy as it transitions from confined channel to unconfined plain?

A)Increased deposition and flow halting
B)Decreased sediment concentration
C)Amplified erosion of plain sediments
D)Elevation of flow pressure

💡 Explanation

Increased lahar deposition occurs because energy dissipation triggers the **flow deceleration and spreading** over a wide unconfined area leading to increased friction and decreased carrying capacity; therefore, deposition occurs rather than erosion or pressure increase which occur in constricted settings.
