The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources. For example, snow cover and asphalt insulate the ground and homes can heat the ground (see also heat island). The line varies by latitude, it is deeper closer to the poles.
In New York City, ten people are killed and power is lost across upper Manhattan and the Bronx. December 11: New York Giants won their 3rd NFL championship, defeated the Green Bay Packers, 23–17. Bronx High School of Science and The Cloisters museum established.
In astronomy or planetary science, the frost line, also known as the snow line or ice line, is the minimum distance from the central protostar of a solar nebula where the temperature is low enough for volatile compounds such as water, ammonia, methane, carbon dioxide and carbon monoxide to condense into solid grains, which will allow their accretion into planetesimals.
In geology, the frost line is the level down to which the soil will normally freeze each winter. By an analogy, the term is introduced in other areas. Frost line (astrophysics), a particular distance in the solar nebula from the central protosun where it is cool enough for hydrogen compounds such as water, ammonia, and methane to condense into solid ice grains.
Manhattan (/ m æ n ˈ h æ t ən, m ə n-/ ⓘ man-HAT-ən, mən-) is the most densely populated and geographically smallest of the five boroughs of New York City.Coextensive with New York County, Manhattan is the smallest county by geographical area in the U.S. state of New York.
The distance from the die is called the height of the frost line. It depends on various factors, including the melt temperature, the speed of cooling, the extrusion speed, and the diameter of the bubble. The notion is important, since the higher the frost line, the more difficult to control the uniformity of the film thickness.
