What can cause an increase in the density of ocean water? How does an aquifer work? Why has groundwater use increased overall in recent years? What causes the water table to rise and fall? How does water pollut
What three factors control surface currents? Why does sound travel faster in lower density materials and in hotter materials? How does increasing the resistance in a circuit affect the current in the wire? What things influence deep ocean currents?

Because of its high temperature, the outer core exists in a low viscosity fluid-state that undergoes turbulent convection and rotates faster than the rest of the planet. This causes eddy currents to form in the fluid core, which in turn creates a dynamo effect that is believed to influence E...
Ocean Currents The main causes of ocean currents are wind, the Earth's rotation and differences in water density within oceans. Different types include surface currents, deep ocean currents and tidal currents. The majority of the world's oceans' surface currents are caused by the wind. The most...
Auroras tell us many things about Earth's upper atmosphere, including its density, composition, flow speeds, and the strength of electrical currents flowing in the upper atmosphere. These in turn tell us about the Earth's magnetic field, how it extends into space, and how it changes dynamicall...
(c.f. Sections "Power consumption" and "MR compatibility"). The packaging (COB, ball grid array (BGA)), the package size, the die size before packaging and the number of readout channels, etc., also normalized to the package size, i.e., the channel density, might be important ...
An alternative to PWM is pulse-density modulation (PDM), in which the number of pulses in a given time window is proportional to the average value of the input audio signal. Individual pulse widths cannot be arbitrary as in PWM, but are instead “quantized” to multiples of the modulator ...
total current is the sum of a conduction current and a displacement current. Conduction current density is associated with electric conductivity and displacement current density is associated with electric permittivity. Electroquasistatics can be seen as a dynamic version of the steady current equations...
Why Do Convection Currents Form? A temperature difference causes particles to move, creating a current. In gases andplasma, a temperature difference also leads to higher- and lower-density regions whereatomsandmoleculesmove to fill in areas oflow pressure. ...
