- The Earth is not in thermal equilibrium with sun, Why?arrow_forwardAt night, the surface of the earth cools, mostly by radiation. The surface radiates energy upward; the much cooler sky above radiates much less. Patches of ground under trees can stay warmer, which is why, if you livesomewhere that has cold, clear nights, you may have noticed some mornings when there is frost on open patches of ground but not under trees. Why does being under a tree keep the ground warmer?arrow_forwardRadiation is emitted(a) only by glowing objects such as the Sun.(b) only by objects whose temperature is greater than thetemperature of the surroundings.(c) only by objects with more caloric than their surroundings.(d) by any object not at 0 K.(e) only by objects that have a large specific heat.arrow_forward
