Convection Current -
(electronics) The time rate at which the electric charges of an electron str
eam are transported through a given surface.
(geophysics) Mass movement of subcrustal or mantle material as the resu
lt of temperature variations.
(meteorology) Any current of air involved in convection; usually, the up
ward-moving portion of a convection circulation, such as a thermal or th
e updraft in cumulus clouds. Also known as convective current.
Spreading Boundaries -
(geophysics) where the tectonic plates are separating.
Collision Boundaries -
(geophysics) when the two plates push almost equally against each othe
r, buckling the material up in the middle.
Transforming Boundaries -
(geophysics)occur when tectonic plates slide and grind against each othe
r along a transform fault. The relative motion of such plates is horizontal
in either sinistral or dextral direction.
