Because 4 degrees Celsius is higher than 0 degrees Celsius
Yes, flowing water can freeze even if it is moving, as long as the temperature is below freezing point.
Yes you can I have it on good authority that you can freeze anything. You can even freeze your posterior off in really cold weather. So be careful!
A leak from any water hose or the water pump, or even a freeze plug may be dripping down the side of the engine, making it appear it is a leak from under the engine. You need to get under the vrhicle to find exactly where the coolant is leaking from.
Moving water does freeze, but at a lower temperature than still water. This is due to the mechanical action of moving water continuously breaking up the formation of ice crystals, which is why rivers and streams can appear to flow even in cold temperatures. However, when the temperature is low enough, even moving water will eventually freeze.
Farmers have found that flooding the roots before a hard freeze helps keep the tree alive, even if the leaves freeze.
The sun heats the water surface. Warm water has a lighter density than cold water so the warmer water floats on the surface of the colder water.
No, there is no rainfall on Venus, even if there was, the water would evaporate before it even touched the surface as it is about 400 °C.
Water is evaporated from the external layer of water.
In short, certain areas have radioactivity, which can contaminate ground water, even long after surface water has regenerated itself. Even floods, sink holes-all kinds of things, can cause water to become contaminated. Surface water can be contaminated easily, by farmers' chemicals, oil from vehicles, including watercraft. Anything that contaminates can get to surface water.
By definition, ice is frozen water. If it doesn't freeze it isn't ice.There is no liquid water at the south pole. The north pole is generally frozen as well, but bear in mind, the freezing point for sea water is much lower than that of pure water. Salt is a type of anti-freeze. So during the summer, you can have open water even at the north pole.
All reptiles breathe using lungs, they cannot survive under water for a long time. Even if they spend their lives entirely in water, they have to often swim to the surface to take another breath.
It gets real close to freezing up in the airplanes and vehicles used in the Arctic and Antarctic weather. I think its molecules can't compress enough to totally stop all movement. It can freeze if the temperature is low enough.
