factors affecting temperature
thinning atmosphere and low atmospheric pressure causes what
- 1) uv radiation
- -a large fraction of total radiation
- -less atmosphere to trap and radiate heat back to ground
- -the energy pf motion (kinetic energy) required to sustain the greater movement of air molecules in the expanding air mass is drawn from the surroundngs, which coll as a result
- 2) expanding air l loses energy causing cooling with altitude
