Answer:
1. Most comets are made up of a mixture of water ice, dust, and various volatile substances such as methane, ammonia, and carbon dioxide.
2. The dry ice, or frozen carbon dioxide, in a comet can sublimate, or transition from a solid directly to a gas, when the comet gets close to the sun. This process can create a coma, or a cloud of gas and dust, around the nucleus of the comet.
3. Some people think that the term "dirty snowball" is an accurate way to describe comets because they are made up of a mixture of water ice, dust, and volatile substances, and they can appear to be dark and dirty when viewed from afar. However, others argue that the term does not accurately convey the complexity and diversity of comets, which can vary greatly in size, composition, and behavior.
Answer:
1. Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices.
2. The dry ice will create a cool, cloudy vapor that is safe to touch.
3. The gas contains water vapor, carbon monoxide, carbon dioxide and other trace substances, and is eventually swept into the distinctive comet tail.
Explanation:
1) They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.
2) according to NASA, with the ice composed mainly of frozen water but perhaps other frozen substances as well, such as ammonia, carbon dioxide, carbon monoxide and methane.
3) Scientists sometimes call comets dirty snowballs or snowy dirtballs, depending on whether they contain more ice material or rocky debris according to NASA.
