Cho et al. ◀ Strength-reducing mechanisms in mantle rock during the Flood ▶ 2018 ICC 718 Figure 7 . Temperature snapshots from the TERRA2D simulation at the times of 5 days, 20 days, and 60 days after the Flood started. The arrows show the velocity fields of mantle flow. Initially, the cold blob rapidly descended with the maximum velocity of 1.1 m/s. As the gravitational potential energy decreases with time, the mantle’s downwelling velocity decreases due to the reduction of the driving force from the gravitational potential energy. At the top surface, the ascending plume pushes the cold dense rock toward the downwelling zone. Note that the increase in the temperature around the descending blob due to the shear (or frictional) heating. The shear heating decreases the viscosity of rock (see Figure 12) leading to the catastrophic runaway process.
