Geology can also include the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon. Modern geology significantly overlaps all other earth sciences , including hydrology and the atmospheric sciences , and so is treated as one major aspect of integrated earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure.

It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. Geology provides the primary evidence for plate tectonics , the evolutionary history of life , and the Earth’s past climates. Geologists use a wide variety of methods to understand the Earth’s structure and evolution, including field work , rock description , geophysical techniques , chemical analysis , physical experiments , and numerical modelling.

In practical terms, geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources , understanding of natural hazards , the remediation of environmental problems, and providing insights into past climate change. Geology is a major academic discipline , and it plays an important role in geotechnical engineering. The majority of geological data comes from research on solid Earth materials.

Nicolaus Steno introduced basic principles of stratigraphy, the study of layered rocks, in [ 1 ]. William Smith , working with the strata of English coal mines, noticed that strata and their sequence were consistent throughout the region. The figure of this geologic time scale shows the names of the units and subunits. Using this time scale, geologists can place all events of Earth history in order without ever knowing their numerical ages.

Add a note 1. Time and Geology The immensity of geologic time is hard for humans to perceive. It is unusual for someone to live a hundred years, but a person would have to live 10, times that long to observe a geologic process that takes a million years. In this chapter, we try to help you develop a sense of the vast amounts of time over which geologic processes have been at work. Geologists working in the field or with maps or illustrations in a laboratory are concerned with relative time – unraveling the sequence in which geologic events occurred.

Overview of Relative and Absolute Dating

Basic concepts of chemistry are essential to understanding the physical and chemical properties of earth materials minerals, rocks, organic matter, etc. The chemical characteristics of earth materials are reflect the environments how and where they are formed, they also determine their potential fate when exposed to chemical changes.

For instance, rocks and minerals formed deep underground may not be stable in the surface environment where they are exposed to water, air, temperature changes, and other physical and chemical conditions. All matter is made up of atoms , and atoms are made up of atomic particles electrons , protons , and neutrons – see Figure

The figure of this geologic time scale shows the names of the units and subunits. Using this time scale, geologists can place all events of Earth history in order without ever knowing their numerical ages. The specific events within Earth history are discussed in Chapter 8.

By Beth Geiger. June 13, at am. Imagine the nearly unimaginable: 4. To grasp just how old Earth is, imagine fitting its entire history into one calendar year. Fish first swam onto the scene in late November. Dinosaurs stomped around from December 16 until December The first modern humans — Homo sapiens — were real late-comers. Almost as mind-boggling is how geologists figured this all out.

Put together, the rock records the long saga of life on Earth. It shows how and when species evolved. It also marks when they thrived — and when, over millions of years, most of them went extinct. Limestone or shale, for example, may be the remains of long-gone oceans.
