Geology

From ancient to modern, there is glimpsed development in the study of the natural science of geology. Everything started with the origin of Earth and some of the foremost geological studies were also targeted on the origin of Earth. The changes in geology were observed and then evidence-based concepts were correlated to the geological domain and earth's physical changes.

Exclusively not only one person was involved to form the vast array of geology, but the contribution of many philosophers, scientists, and many other great people led the geology from Antiquity to Modern.

In the early modern era, geologists used to focus on topics associated with historical geology; Earth's age, and the norms by which Earth formation was established. In the later 20th century geology is now studied in a more comprehensive context, using a wider range of approaches.

It was considered that Earth came into creation approximately six thousand years ago. As far as we go more into the understanding of earth structure it was agreed that bedrock consisted of long and parallel layers that are various angles so as the weathering including sediments deposition by water was led to form a stone. According to Scottish naturalist James Hutton, recognized that sedimentation is a slow process, so it is to be said that the oldest rocks are also made. In this case, the occurrence of the reverse process is when the rock is exposed to the atmosphere so it will erode and decay. This "geological cycle” has been achieved numerous times.

So, how do we know Earth's age? It is not determined by unpretentious observation, it is specified with the study of materials. A significant method for determining the age of the earth from the sample is radiometric dating. As older crystal formations suggest the earth had solid ground as early as 4.2 billion years ago and uranium has a half-life of 4,470 million years almost close to the age of Earth itself.

The changes in earth formation cannot be observed just during one person's lifetime; it is a slow process. Interest towards the geology delivers to study the processes and creation of landforms, not limited but entangled with deep insights of transformation that earth has undergone over the billions of years.
