What is tectonics?

tectonics, also known as plate tectonics, is a theoretical understanding of how the Earth's surface is constantly changing. To the best of the science understanding, giant tectonic plates always move very slowly because the Earth creates a new bark and gains the regeneration of old bark. The effect was often compared with a giant transport belt. There are certain points under the ocean where the bark is generated, and they look like mountains, while other areas that look like trenches are places where older crust segments are regenerated. Understanding the tectonics of the board is generally used to explain many geological occurrences on Earth, including earthquakes and volcanoes.

There are three main types of boundaries between different plates around Earth. Some move together, some move apart and others move sideways side by side. At the edges of these boundaries, there are things like volcanoes and earthquakes, more common, because the Earth is moving and leaving the holes to climb up and because the movement between the plates generates friction. Many edgesThe anal areas are near the coast of the ocean, which is one of the reasons why these areas are often more susceptible to geological activity. Studies have shown that continents move at an equivalent of 4 inches (about 10 cm) per year.

The whole idea of ​​plate tectonics is a more advanced version of the idea developed at the beginning of the 20th year called Continental Drift. During this time, a scientist named Alfred Wegener decided to explore some of the obvious facts that found it curious about how the country was together. Between the edges of the continents where it looked as if they had disintegrated at some point. Wegener began to examine fossil records in these areas and found that there were surprising similarities to Amshed that they had guaranteed further investigation. For example, he found fossils of ancient plants and animals that were identical in areas separated by the ocean.

Wegener began to believe that the continents were moving the greatEven slowly on the Earth's surface, and even theorized that almost the whole country on Earth was once part of a giant only continent. Wegener's problem was that he couldn't explain how it was happening, and other scientists were very skeptical. In 1929, a scientist named Arthur Holmes came up with the basic idea for the present mechanism, but most scientists did not accept this theory until the 1960s. Since then, a lot of evidence has been collected that supports the theory, and it is widely considered to be a reality.
