The surface of the Earth is divided into pieces called "tectonic plates." When these plates move, they do not move smoothly. They may rub against each other, creating tremendous friction and energy. The force of these movements can shake the surface of the Earth, resulting in what is commonly known as an earthquake. Some parts of the world get more earthquakes than other parts. The parts of the earth that get most earthquakes are near the edges of these plates.
