In order for snow to melt, the temperature needs to reach at least 32 degrees Fahrenheit (0 degrees Celsius). This is when the snowflakes will start to lose their shape and turn into water droplets.
The amount of snow that can melt in a certain temperature depends on the density of the snow. In general, 1 cm of snow will produce about 1 millimeter of water when melted. So, 60 cm of snow would produce about 60 millimeters (or 6 centimeters) of water when melted.
The time it takes for snow to melt in a certain temperature varies depending on various factors such as the density of the snow, the intensity of the sunlight, and the temperature fluctuations. Generally, it can take several hours to a few days for 60 cm of snow to completely melt in 4 degrees.
Yes, it is possible for snow to melt at temperatures lower than 4 degrees. This is due to a process called sublimation, where the snow turns directly into water vapor without going through the liquid phase. However, sublimation is a slower process and may not completely melt 60 cm of snow in a short amount of time.
The melting of snow can have both positive and negative effects on the environment. On one hand, it can provide water for plants and animals, replenish water sources, and help regulate the Earth's temperature. On the other hand, it can also lead to flooding and erosion, and can disrupt ecosystems by changing the timing of plant growth and animal migrations.
