# [https://en.wikipedia.org/wiki/Chicxulub_crater Chicxulub crater] says the impactor diameter ranges from 11 to 81 km. The cite is to a preprint, not a [https://en.wikipedia.org/wiki/Wikipedia:Reliable_sources WP:RS]. 81 is likely a typo for 18. Anyway we can't use it. Most often given as 10-15 km and here is a cite<ref>

# [[Wikipedia:Dew_point]] - says ''"When the temperature is below the freezing point of water, the dew point is called the frost point"'' <br /> This is a common misconception. Dew point is the temperature for 100% humidity in normal conditions (no ice present). Frost point is the temperature for 100% humidity over an ice surface, a higher temperature. This distinction matters for growth of ice in clouds..<ref>The meteorologist Jeff Haby explains [http://www.theweatherprediction.com/habyhints/347/ here] {{quote|"The dew point is the temperature at which the air is saturated with respect to water vapor over a liquid surface. When the temperature is equal to the dewpoint then the relative humidity is 100%. The common ways for the relative humidity to be 100% is to 1) cool the air to the dewpoint, 2) evaporate moisture into the air until the air is saturated, 3) lift the air until it adiabatically cools to the dew point. <br /> "The frost point is the temperature at which the air is saturated with respect to water vapor over an ice surface. It is more difficult more water molecules to escape a frozen surface as compared to a liquid surface since an ice has a stronger bonding between neighboring water molecules. Because of this, the frost point is greater in temperature than the dew point. This fact is important to precipitation growth in clouds. Since the vapor pressure is less over an ice surface as compared to a supercooled liquid surface at the same temperature, when the relative humidity is 100% with respect to water vapor the relative humidity over the ice surface will be greater than 100%. Thus, precipitation growth is favored on the ice particles."}}</ref>
