Geology is the research of the earth (geo means earth, and ology means examine of). In lots of locations, the Grand Canyon in the southwestern United States being a really visible instance, the decrease rock units had been metamorphosed and deformed, after which deformation ended and the upper, undeformed units have been deposited.

Their wider understanding of the Earth and its processes can also be essential, not only for the rocks.

One of the scientific objections to a young earth is the obvious proof that giant plutons of granitic and different igneous intrusive rocks necessarily required tens of millions of years to cool from magmas. 1875 geological map of Europe, compiled by the Belgian geologist André Dumont Colors point out the distribution of different rock types throughout the continent, as they had been recognized then.

In addition to figuring out rocks in the area ( lithology ), petrologists establish rock samples in the laboratory. The science devoted to the examine of the Earth , particularly the stable Earth and the rocks that compose it. Geologists study Earth processes: Many processes akin to landslides , earthquakes , floods, and volcanic eruptions could be hazardous to individuals.
