Does Mars have an atmosphere?
 * WONDER QUESTION:**
 * Mars has an atmosphere and clouds.
 * Also, guess what, Mars does have water, except it is frozen and some of it is under the ground. Talk about wearing layers!
 * While on the subject of water, water dissolves more substances than any other liquid.
 * Talking about dissolving, only things that are polar dissolve.
 * Talking about polar, did you know that the Polar Bear is one of Earth's largest land predators?
 * Talking about things that are cold, did you know that a old style mercury thermometer will freeze at thirty-eight degrees below zero?
