To think, you must stop. You physically must stop talking! So when we are in talk mode, especially fast talk mode, we are in a zone that puts our thinking selves aside. To awaken the thinking brain, we must stop talking. Great thinkers know this, and will use lines like, Let me think about that for a second..
Definition of turbulent flow. : a fluid flow in which the velocity at a given point varies erratically in magnitude and direction â compare laminar flow.
A pyroclastic flow is a fast-moving current of hot gas and volcanic matter that moves away from a volcano reaching speeds of up to 700 km/h. The gases can reach temperatures of about 1,000 Â°C. Pyroclastic flows are a common and devastating result of certain explosive eruptions; they normally touch the ground and hurtle downhill, or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope.
