This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is left behind. As the seawater gets saltier, its density increases, and it starts to sink.
A mineral is a naturally occurring,inorganic, crystalline substance that aggregate to form rocks. Geologists separate minerals into classes based on their chemical composition. The different classes of minerals include halides, oxides, phosphates and sillicates. Rocks are usually classified based on the grouping and composition of minerals in rocks.

Explanation:
Argentina took in many Nazi war criminals and members of the Nazi party after World War II in part because of the strong presence of German immigration in the South American country. Argentina had received many Germans in the decades prior to the war which helped the country stay close to Germany.
