The drawing shows the dynamo mechanism that creates Earth's magnetic field: convection currents of fluid metal in Earth's outer core, which are driven by heat flow from the inner core, organized into rolls by the Coriolis force, create circulating electric currents, which generate the magnetic f...
This creates a dynamo effect, or convections and currents within the core. This, in turn, creates Earth's magnetic field — it's like a giant electromagnet. When the solar wind reaches Earth, it collides with the magnetic field, or magnetosphere, rather than with the atmosphere. By far, ...
Why does earth bulge at the equator? What will happen to the convection currents in the mantle if the Earth's interior eventually cools down? From a plate tectonic perspective, how does the orogenic activity that occurred in the Cordilleran mobile belt during the Mesozoi...
Yet, as the sunrise and sunset indicate, the earth rotates in that same direction. Does that mean that the atmosphere is rotating around the planet faster than the planet itself is spinning? Shouldn’t it be just the opposite? Charles Barksdale, Baltimore Illustration by Slug Signorino Cecil ...
The Venusian magnetic field does not appear to have an active dynamo in part due to its very slow rotation (∼6.5 km/h). Its origin has been related more to the interaction between the ionosphere and the solar wind, rather than by an internal dynamo like the Earth (e.g., Kivelson ...
Why do weather satellites circle the earth at different altitudes? How do clouds and precipitation in the atmosphere develop? Why does the high specific heat of water have to do with convection currents in the air at the seashore? Why do climates near the coasts ten...
Geologists have hypothesized that the movement of tectonic plates is related toconvection currents in the earth's mantle. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up th...
The outermost layer of Earth, lithosphere, a rocky and brittle layer, is broken into pieces called plate tectonics.The plate tectonicsfloat/move over the asthenosphere. Convection currents in the mantle cause the plate tectonic's movement.
The anomalous cyclone propagated eastward and merged with the local anomalous convection in WP forced by warm SSTA in CP. As a result, there were large-scale westerly anomalies over the WP in the northern winter of 1986/87. In addition, we also examine the strength of SWS in CP and HF ...
Why is the electric field inside a conductor zero? How does the electric field become zero in a conductor? Why does air friction affect a car's gas mileage? Why does the high specific heat of water have to do with convection currents in the air at the seashore?
