A convection current requires a heat source and a fluid that can circulate to transfer heat. In the atmosphere, the heat source is the sun and the fluid is air. Inside the Earth, the heat source is the core and the fluid is magma. Significance Convection currents can move large masses of...
24)Convection currents are the continuous loop of sinking and rising hot, soft rocks caused by energy transfer in the asthenosphere (mantle) of Earth 25)Heat from the mantle and core creates convection currents. 26)Convections currents in the mantle cause the tectonic plates to move. 27)Where ...
Is steady convection possible in the Earth’s magnetotail?, Geophys - Erickson, Wolf - 1980 () Citation Context ...and downward current at the dawnward edge. These flow channels take the form of underpopulated flux tubes. This idea is important because it may provide a solution to the so...
Windis an example of a convection current. Sunlight or reflected light radiates heat, setting up a temperature difference that causes air to move. Shady or moist areas are cooler, or able to absorb heat, adding to the effect. Convection currents are part of what drives the global circulation ...

The structures inside the stellar disk can also be compared with structures seen on the limb of the star. In Fig.3a, we show the half-power radius as a function of position angle for the three highest angular resolution epochs. There is a good correspondence between the epochs, with specifi...
The large-scale convection electric field plays an important role in the dynamics and structures of the inner magnetosphere, such as the plasmasphere, ring current, the outer radiation belt and plasma sheet [1--7]. It is well known that dawn-dusk quasi-static electric field can be produced ...
Here, we review the current knowledge and future direction of ocean convection arising from sea–surface interactions, with a focus on mixed layer, open-ocean, and polynya convection. Keywords: turbulent convection; surface buoyancy forcing; mixed layer dynamics; convective heat flux; ocean ...
the current trend of fulfilling the above goals are to use nanofluids instead of common fluids because nanoparticles have hundred-time greater thermal conductivity compared to liquid [18]. This trend makes the nanofluids a promising contender for high-performance coolant in various applications including...
We review the current status of efforts to model, in considerable detail, the entropy structure of the solar convection zone, in particular the layers near the surface of the Sun. Given an accurate, tabular equation of state, tables of continuous and binned spectral line opacities, suitable ...
