Aplanet’s temperature depends on its distance from the sun as well as the strength of its greenhouse effect. let’s remove the effect of distance from the sun by just considering how the temperature of a planet changes due to the presence of its atmosphere. from the numbers given in the animation, calculate the difference in temperature for each planet with and without its atmosphere, and then rank the planets in order of increasing greenhouse effect.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
