Chapter 2-a energy: warm/cooling the earth and its atmosphere. 3) radiation and the global energy balance (in part b); Energy: the capacity to do work on some object/fluid/form of matter; can drive the atmosphere. 1) kinetic energy (ke): energy of a moving object: ke = m, v2 m: mass measured in [kg]; v: velocity in meters/second [m/s]; In the warm volume of air, the molecules move faster and farther apart: measured in units of [ c], [ f], or using kelvin scale [k], at absolute zero [0 k = -273. 15 c] (theoretically) atomic motion ceases, temperature scales. Celsius scale: 0 c water/ice melts, 100 c water boils (at sea level pressure); Fahrenheit scale: 32 f water freezes, 212 f water boils; Earth"s surface forms (rocks, soils, and) the diversity of landscapes: biosphere, influencing the types of vegetation and animal life that inhabit an area.
