The euro is the most tangible proof of European integration – the common currency in 19 out of 28 EU countries and used by some 338.6 million people every day. The benefits of the common currency are immediately obvious to anyone travelling abroad or shopping online on websites based in another EU country.
The Economic and Monetary Union involves the coordination of economic and fiscal policies, a common monetary policy and the euro as the common currency. The euro was launched on 1 January 1999 as a virtual currency for cash-less payments and accounting purposes. Banknotes and coins were introduced on 1 January 2002.

Spain is divided in 17 parts called autonomous communities. Autonomous means that each of these autonomous communities has its own Executive Power, its own Legislative Power and its own Judicial Power. These are similar, but NOT the same, to states in the United States of America, for example.
Spain has fifty smaller parts called provinces. In 1978 these parts came together, making the autonomous communities. Before then, some of these provinces were together but were broken. The groups that were together once before are called "historic communities": Catalonia, Basque Country, Galicia and Andalusia.
The Spanish language is the sole official language in every autonomous community but six, where Spanish is co-official with other languages, as follows:
Earth, our home, is the third planet from the sun. It is the only planet known to have an atmosphere containing free oxygen, oceans of liquid water on its surface, and, of course, life.
Earth is the fifth largest of the planets in the solar system — smaller than the four gas giants, Jupiter, Saturn, Uranusand Neptune, but larger than the three other rocky planets, Mercury, Marsand Venus.
Earth spins on an imaginary line called an axis that runs from the North Pole to the South Pole, while also orbiting the sun. It takes Earth 23.439 hours to complete a rotation on its axis, and roughly 365.26 days to complete an orbit around the sun.
Earth's axis of rotation is tilted in relation to the ecliptic plane, an imaginary surface through Earth's orbit around the sun. This means the northern and southern hemispheres will sometimes point toward or away from the sun depending on the time of year, varying the amount of light they receive and causing the seasons.
