### current:

Convection current
* Most convection current is created by heat.
* act similar to the currents produced in a pot of boiling liquid on a hot stove.
* are created from heat rising to the surface of the water
  - responsible for many weather patterns in the troposphere
* carry magma to the surface
  - moisture upwards, which quickly recondenses to form fog
* distribute heat in the atmosphere.
* diverge where they approach the surface.
* explain how the continents move.
* form because of the difference in density between hot and cold air
  - over the vents and bubbles start to rise
* help drag the plate down into the mantle.
* take up nearly one-third of the outer portion of the sun.

* supports music's ability to strengthen the mind as well as our souls.

Dark current
* is electrons generated by the electronics of the camera
  - linear with time for relatively short exposures
  - spurious charge that builds up in each pixel on the CCD during exposure
* is the electric current caused by background noise
  - physically more complicated form of noise
