WebDensity is the amount of mass in a given volume. For example, if you take two full one liter bottles of liquid, one might weigh more, that is it would have greater mass than the other. Because the bottles are both of equal volume, the liquid in the heavier bottle is denser. WebPolarity is the current movement direction. Think of it like a metal spring. Compress the spring on a table and your movement will be down, remove the pressure and the spring pushes back up. Let's call that the resting state of the spring zero. Zero movement, zero current and voltage.

WebEarth’s rotation is also responsible for the circular motion of ocean currents. There are 5 major gyres—expansive currents that span entire oceans—on Earth. There are gyres in the … WebPlate tectonics refers to the movement of the rigid plates around the surface of Earth. The outer portion of the planet, or lithosphere, is relatively rigid because it is relatively cold. The lithosphere varies in thickness but is typically a hundred or so kilometers thick.

"WebCurrent is produced in a metal when the free electrons in the metals acquire a drift velocity due to an electric field. But when these free electrons travel through the metal, their path is hindered by other atoms and particles and their electomagnetic pull. More the resistance, higher is this hindrance and lesser is the drift velocity. " - How do density currents move
