As a geologist with a focus on plate tectonics, I can provide a detailed answer to your question about the number of plates in the world. The Earth's lithosphere is divided into a complex system of tectonic plates that are in constant motion. These plates are crucial to understanding various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.
Step 1: English Answer
The concept of tectonic plates is fundamental to the field of geology. The Earth's lithosphere is broken into several large and small plates that float on the semi-fluid asthenosphere beneath. These plates are in constant motion, driven by the heat from the Earth's interior, which causes convection currents in the mantle.
The number of plates is not a static figure and has changed over geological time. Currently, the Earth is home to seven major tectonic plates, which are the African Plate, Antarctic Plate, Australian Plate, Eurasian Plate, North American Plate, Pacific Plate, and South American Plate. These large plates are responsible for approximately 94% of the Earth's surface area.
In addition to these major plates, there are several smaller plates, including the Arctic Plate, Cocos Plate, Caribbean Plate, Nazca Plate, Philippine Plate, and Juan de Fuca Plate, among others. The exact number of plates can be debated because the boundaries between tectonic plates are not always clear-cut, and new research may redefine the edges or even the existence of certain plates.
The movement of these plates is responsible for the creation and destruction of crust. At divergent boundaries, where plates move apart, new crust is formed as magma rises from the mantle and solidifies. At convergent boundaries, where plates collide, one plate is often forced beneath the other in a process known as subduction, leading to the destruction of the older, denser plate.
The interaction between these plates is what causes earthquakes and volcanic activity. For instance, the Ring of Fire, a region around the Pacific Ocean, is particularly prone to these events due to the active plate boundaries in the area.
It's important to note that the boundaries between plates are not always distinct and can be areas of significant geological activity. These are often marked by triple junctions, where three plates meet. The movement of plates can also lead to the formation of mountain ranges, such as the Himalayas, which were formed by the collision of the Indian Plate with the Eurasian Plate.
In conclusion, while the seven major plates are widely recognized, the total number of plates, including minor ones, is subject to change as our understanding of Earth's geology evolves. The study of these plates and their interactions is vital for understanding the dynamic nature of our planet.

Plate tectonics on Earth, at present, consists of 12 large semirigid plates of irregular shapes and sizes that move over the surface, separated by boundaries that meet at triple junctions. There are also many broad zones of deformation. The seven major plates account for 94% of the surface area of Earth.
