One of the primary uses for a 500-mb map is: to monitor the position of the polar jet stream. to predict surface wind speeds. to estimate surface air temperature. to determine the speed and direction of motion for a mid-latitude cyclone.

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
