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.
you can't really tell how long ice can melt ut if your at a tropical country it should only take about 3-5 mins. and for other countries like u.s and Canada it take about 5-15 mins.
