Geology
Geology is divided into several fields that can be grouped under the main headings of physical and historical geology.
Applied Geology
Applied Geology is geologic knowledge to solving geologic problem. In other words, application of various fields of geology to economic, engineering, water-supply, or environmental problems; geology related to the human activity.
METHODS OF GEOLOGY
Geologists use primary data associated with petrology (the study of rocks), stratigraphy (the observe of sedimentary layers), and structural geology (the have a look at of positions of rock devices and their deformation). In many cases, geologists additionally take a look at contemporary soils, rivers, landscapes, and glaciers; inspect past and contemporary life and biogeochemical pathways, and use geophysical techniques to investigate the subsurface.

Mineral Deposits
Mineral deposits are accumulations of valuable minerals that are of economic interest to humans. These deposits can be found in a variety of geological...

Volcanology is the scientific discipline that focuses on the study of volcanoes, volcanic processes, and the related phenomena that occur within the Earth's crust....
Evaporation and Transpiration
The process through which water is transferred from the surface of the Earth (land surface, free water surfaces, soil water, etc.) to the atmosphere is called evaporation.During evaporation process the latent heat of evaporation is taken from the surface of evaporation.Therefore evaporation is considered as a cooling process. Evaporation from land surface, free water surfaces, soil water, etc. are of great importance in hydrological and meterological studies,

PrecipitationPrecipitation is the release of water from the atmosphere to reach the surface
of the earth.The term ‘precipitation’ covers all forms of water

Hydrogeology
Hydrogeology is a branch of geology that deals with the study of the distribution, movement, and quality of water in the subsurface. Hydrogeology is...
Types of Maps

Physical Properties of Minerals
(How Geologists Identify and Classify Minerals in the Field)Understanding the physical properties of minerals is one of the most fundamental skills in geology. Every...
Unconformities
An unconformity is contact between two rock units.Unconformities are typically buried erosional surfaces that can represent a break in the geologic record of hundreds of millions of years or more. It it called an unconformity because the ages of the layers of rock that are abutting each other are discontinuous at the unconformity. An expected age of layer or layers of rock is/are missing due to the erosion; and, some period in geologic time is not represented.
Engineering Geology
Engineering geology is a branch of geology that focuses on the study of the geological processes, materials, and natural hazards that may affect the...
