Rivers typically need temperatures below 32 degrees Fahrenheit (0 degrees Celsius) for them to freeze over completely.
The time it takes for a pond to freeze completely can vary depending on factors such as the size of the pond, the temperature, and weather conditions. In general, it can take several days to a few weeks for a pond to freeze over completely.
Rivers don't freeze during winter months because the constant flow of water prevents it from reaching the freezing point. The movement of the water helps to break up ice formation, keeping the river from completely freezing over.
Yes, rivers can freeze over during the winter months when temperatures drop low enough for the water to freeze.
Cold weather can cause limestone to deteriorate through a process called freeze-thaw weathering. When water seeps into cracks in the limestone and freezes, it expands, putting pressure on the rock and causing it to crack. Over time, this can lead to the breakdown of the limestone structure.
When you rub the spoon over the ice cream, friction causes the kinetic energy of the water molecules to increase, raising the temperature and preventing freezing. However, when the spoon is left at rest, the heat transfer from the water to the surrounding air reduces its energy, allowing it to freeze on the cold surface of the ice cream.

The Ganges is not said to freeze over. This river, the largest in India, is situated in a geographical area that is generally fairly warm throughout the year. The headwaters of the Ganges are difficult to specify, and those streams high in the Himalayans spring from water that is melted from glaciers or snow. Some of these will freeze in winter. The main flow of the Ganges will, however, never be so cold. A link can be found below to learn more.

Ice would begin to form on the surface- small chunks of ice, floating on the river as ice floes. It happens all the time in rivers in really frigid areas.
Yes, fresh water, especially if it is not fast moving, will freeze. The Polar ice caps show that sea water freezes too.

Yes, the St. Lawrence river freezes over each winter.
Never. The Amazon river is placed on a tropical rain forest which is warm all the time.
Rivers don't freeze during winter months because the constant flow of water prevents it from reaching the freezing point. The movement of the water helps to break up ice formation, keeping the river from completely freezing over.
