The plume is initially symmetric, but then its head detaches as it approaches its maximum height. The detached head is denser than the fluid in the plume below it, and the interaction between the sinking head and the rising plume causes a sideways deflection; as this cycle is repeated, the...
For thousands of years, humans, and plants and animals long before that, have been using frozen "sky water" to keep warm. which sort of doesn't make sense.几千年来，人类，动植物都使用雪来取暖，这毫无道理。Because snow is cool.因为雪是凉的。You might even say it's… ice cold.甚至是...
1.Whales,seals and walruses stay warm in cold water because they have a thick layer of blubber.We humans rely on something like blubber-neoprene rubber wet suits-to spend time in cold water.But the thick versions for really icy water are heavy and clumsy.So rather than taking after big ...
Extreme wildfires have devastating impacts on multiple fronts, and associated carbon greatly heats the earth’s climate. Whether and how to predict wildfires becomes a critical question. In this study, we find that the preceding-winter “warm Arctic-cold
which has been shown to cause mortality in deep water corals118. This may be a particular problem for deep reefs when the continental margin is very steep, such as the Gulf of Aqaba, where deep reefs are found much closer to the shore. Additionally, an area over 7 km2that was highly...
Please explain thoroughly why ice is less denser than liquid water. How does crosslink density affect the polymer glass transition temperature? How does temperature change affect surface tension? Why is the volume of an ice cube is greater compared to when it melts to form liquid water? How ...

Steel is made almost entirely of iron atoms, but it is denser than iron. Suggest a reason for this. If salt lowers the melting point of ice, what does that mean? What will cause the ice to melt? What is the difference between constant ...
The denser the hairs, the more the air can be carried with.C. The researchers have studied how this air-trapping insulation mechanism might work.D. Cold-water divers and surfers can emulate otters or beavers now.65. What can make the little mammals keep warm in cold water?A. A thick ...
The primary motivation for this work is thus to observe and identify the processes by which PSW subducts. It may seem intuitive that this incoming warm but salty (denser) water would slide under the fresh (lighter) surface water in the BG. However, water of different densities may stably si...
