Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other. The movement of the plates, and the activity inside the Earth, is called plate tectonics. Plate tectonics cause earthquakes and volcanoes. The point where two plates meet is called a plate boundary. Earthquakes and volcanoes are most likely to occur either on or near plate boundaries. The map shows the world's tectonic plates and the distribution of earthquakes and volcanoes. The Earth's plates move in different directions.
The Romantic Classical music period ran from 1810 to 1900, and Ludwig van Beethoven is regarded as the first Romantic composer, no doubt due to the passion and detail that fueled his works. Beethoven's music was a direct reflection of the point in time in which he lived.
Unlike the Renaissance or Baroque eras, which included many important composers and trends, the choral music of the classical era was dominated by three composers: Franz Joseph Haydn (1732-1809), Wolfgang Amadeus Mozart (1756-1791), and Ludwig van Beethoven (1770-1827).
