The tumbleweed dispersal strategies are unusual among plants; most species disperse their seeds by other mechanisms. Many tumbleweeds (though by no means all) are ruderal species, opportunistic agricultural weeds. Tumbleweeds have been recorded in the following plant families:
The most obvious is temperature. If the air temperature is above 32Â°F snow and ice will start to melt, at or below 32Â° and it will remain frozen. Think about a popsicleâ¦ inside the freezer it stays frozen, outside it starts to melt. The amount of sunshine plays a big factor.
  It will start to melt if the temperature rises above 0 degrees Celsius or 32 degrees Fahrenheit                   Officially, the mel â¦ ting temperature of ice is zero degrees Celsius (or 32F). The freezing temperature does vary dependent on the electrolytes added to the water solution.ce melts at a temperature of 32 Fahrenheit and 0 Celsius.Yes, ice begins to melt at any temperature above 0 Celsius    Ice starts melying at 33 deggrees ferrihnhieght. â¦ That start to freeze at 32 degrees ferhinhieght.
