Amazing facts about everything

How does the Arctic  Ocean freeze? Arctic sea ice is one that forms on the Arctic Ocean during the winter months. Pure water, which does not contain any other molecules, substances or impurities, freezes at 0 ° C (32 ° F). On the other hand, about 3.5 percent of the world's seawater contains dissolved minerals and salts. This additional material reduces the freezing point of seawater to about −2 ° C (28.4 ° F) because the freezing point depends on the number of molecules present in a solution, as well as the type of molecule. During the winter months, when air temperatures in the Arctic begin to drop dramatically, a deep layer of seawater begins to develop minuscule ice crystals; This dirty water is called Fragile Ice. Another drop in temperature causes Friesil's ice to become thick. Pockets of salty slash accumulate until they become so heavy that they begin to sink. This leaves the top layer of icy crystals with a significantly lower salt content. The freezing poi...

Why is the coast eroding? Learn about the amazing processes that are building and breaking our shores right now…. Water is not given enough credit for its role in shaping the Earth. Tectonic plates and volcanic eruptions are often cited as the culprits for most land characteristics, but it is the water and wave action that shape the beaches of our world.  When a wave crashes on shore it carries sediment that gets suspended in water, and it also pushes large sediment along the ground. When a wave is heard it also carries the sediment with it, but rarely at a uniform rate.  If a wave accumulates more sediment then it goes away, then it becomes sediment, which expands the coastline. Conversely, when more sediment is being removed than added, the coastline is reoriented or destroyed. Coastal erosion today accounts for the most amazing landforms in Australia from the Twelve Apostles to the White Cliffs of Dover, England. The type of coastline form...
