Convection currents flow in the asthenosphere. 1. The heat source for these currents is heat from Earth's core and from the mantle itself. 2. Hot columns of ...Feb 1, 2011 · Convection is when different parts of a fluid move in a more-or-less circular path, with parts of the fluid at the bottom moving to the top and vice versa. Here fluids refer to both liquids and gases. Convection happens when you have two fluids together that are different densities, but we can come up with a more detailed explanation than that. Convection is the exchange of heat energy by the development of a liquid (fluid or gas) between regions of various temperatures. Warm air is less dense than cold air, thus convection flows are created within the sight of a temperature angle. At the point when flows are created distinctly by temperature-inferred density contrasts in the liquid ... The differences in the temperature at the Earth’s interior and surface cause convection currents to occur within the mantle. Lithospheric plates are the parts of the uppermost layer of the Earth, and they are flowing in an area called the asthenosphere. The asthenosphere is a soft, less rigid upper part of the mantle where the lithospheric ...
What causes the convection currents in the mantle? It is caused by the difference in temperature and density. Heating and cooling of the fluid, changes in the fluid density, and the force of gravity, combine to set convection currents in motion.
