Earth’s core is mostly made of iron and nickel. It consists of a solid center surrounded by an outer layer of liquid. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles).

The Earth’s molten iron core creates a magnetic field. The Earth is like a great big magnet, with poles at the top and bottom near to the actual geographic poles. The magnetic field it creates extends thousands of kilometers out from the surface of the Earth – forming a region called the “magnetosphere“. Scientists think that this magnetic field is generated by the molten outer core of the Earth, where heat creates convection motions of conducting materials to generate electric currents.

The first chemically confirmed beer dates back to the 5th millennium BC in Iran, and was recorded in the written history of ancient Egypt and Mesopotamia and spread throughout the world.

Revered as one of the most famous and influential figures in art history, Vincent van Gogh lived a peculiar life. Van Gogh only started painting at the relatively late age of 27 and was mostly self-taught. As he became famous only after his suicide, he came to be seen as a misunderstood genius in the public imagination. His reputation grew in the early 20th century as elements of his style came to be incorporated by the Fauves and German Expressionists. He attained widespread critical and commercial success over the ensuing decades, and is remembered as an important but tragic painter whose troubled personality typifies the romantic ideal of the tortured artist. Today, Van Gogh’s works are among the world’s most expensive paintings to have ever sold, and his legacy is honoured by a museum in his name, the Van Gogh Museum in Amsterdam, which holds the world’s largest collection of his paintings and drawings.
