Plate tectonics: theory, mechanisms, and geological implications

Plate-Tectonic

The earth that we live in, from the scientific study, are formed from massive materials from millions of years ago. Scientists and geologists never stop the study of every inch of the earth's composition, but up to now, questions and debates brought up issues and fascinating stories of how the earth and its components were formed.

The history and evolution of the earth, its continents, and the bodies of water, are still yet to be proved. From the history of the solar system, the earth was formed from a large amount of rocky debris that fall together to form our planet. A massive material however crashed to the earth, melted its composition, solidified later, and formed crusts that created the earth's continents.

These crusts are unfathomable, too deep to enable scientists to conduct a study of what composes them and the various chemical processes that take place underneath the crusts. Only the natural activities, such as eruption of volcanoes, allow scientists to examine the geological features of the earth's surface that continuously changes its formation due to the plate tectonic activities. Plate tectonics, as defined in the article, is the continuous motion of parts of the earth's surface that causes its changes. Compared to Venus, our sister planet, the earth changes its components faster. In fact, Magellan's space probe orbiting radar found that plate tectonics do not occur in Venus. Venus doesn't show signs of equivalent processes the earth's surface experiences.
