In summarizing how the atmosphere is warmed, we said that first, solar passes through the atmosphere unimpeded, heating the ground upon impact. The ground then warms the first few inches of the atmosphere through . As the surface air warms, it becomes less dense and rises, carrying heat vertically through which can then move horizontally through .

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
