The emoticon is made up of the letters X and D, where X is the eyes all scrunched up, and D represents a really big mouth that is laughing. XD has a similar meaning to LOL, or âlaughing out loud,â in Internet slang. To see the face created by the letters XD, one can turn her head anticlockwise. Using a colon next to a capital D or typing X-D during an Internet chat also means the person is laughing crazily.Learn more about Mobile.

(from Wikimedia Commons). Stream load is a geologic term referring to the solid matter carried by a stream (Strahler and Strahler, 2006). Erosion and bed shear stress continually remove mineral material from the bed and banks of the stream channel, adding this material to the regular flow of water. The amount of solid load that a stream can carry, or stream capacity, is measured in metric tons per day, passing a given location.
