How Minerals Form ?

Minerals can form on the surface through evaporation of solutions containing dissolved minerals. Minerals can form beneath the surface when dissolved elements and compounds leave a hot water solution or when materials melted in magma/ lava then cools & hardens.

How are Islands formed ?

As volcanoes erupt, they build up layers of lava that may eventually break the water’s surface. When the tops of the volcanoes appear above the water, an island is formed. While the volcano is still beneath the ocean surface, it is called a seamount. Oceanic islands can form from different types of volcanoes.



What is the Most Precious Gem in the World ?

 Hope Diamond

  • The Hope Diamond is a large, 45.52-carat, deep-blue diamond, and now housed in the Smithsonian in Washington D.C., United States. The gem has a long and mysterious past, and some people even think it is cursed !
  • The Hope Diamond grew deep within the Earth at high temperatures and pressures, then survived a perilous journey to the surface. No one knows its exact age, but scientists have dated the rocks in which Indian diamonds are found at about 1.1 billion years old.
