William Smith noticed a correlation between rock strata and fossils in 1815, leading to the creation of the geological time scale. The scale is divided into eras, periods, and epochs, with names based on where fossils were found. Radioactive dating allows for precise identification of fossil age. The geological time scale has its origins in […]
Geological oceanography studies the ocean floor, focusing on its structure, topography, and natural processes. It uses oceanographic principles and techniques to discover past and future geological events. Scientists study the effects of lithospheric plate movement, particularly on the continental shelf, to predict water movement and wave height. Sub-disciplines include paleoclimatology and plate tectonics, and scientists […]
Geological formations are groups of rocks with similar characteristics. They can be used to date landscapes, identify mineral deposits, and track geological activity. Formations can be identified by their composition and can be grouped into larger formations or smaller segments. Stratigraphy is the study of rock layers and can be used to create maps of […]
Geological processes, such as plate tectonics, erosion, chemical weathering, and sedimentation, shape the Earth’s surface and are studied by geologists to understand the planet’s history, locate resources, and predict disasters. Plate tectonics drives the movement of continents and explains the formation of mountain ranges and volcanic activity. Erosion, caused by water, ice, and wind, transforms […]
To become a geological mapper, a bachelor’s degree in geology is required, but a master’s degree is preferred. A Ph.D. can lead to higher-paying jobs, but it takes longer to complete. GIS is a valuable tool for geological mappers, and they can work for mining or oil and gas extraction companies, teach at universities, or […]
Geological services are important for industries such as mining and construction. Geologists locate natural resources, predict seismic events, and help avoid hazards. They also work with construction to mitigate environmental impact. Academic geologists study the Earth’s surface and its impact on civilization. Geologists are hired by government agencies to provide mapping and erosion control services. […]
Geological technicians perform tests and analyses on rock, soil, and oil samples to establish possibilities for further production and examination. They work closely with geologists and scientists, use computer applications, and perform meticulous record-keeping and database management. They also supervise exploration and drilling expeditions, perform routine administrative responsibilities, and anticipate consumer demand. The main task […]
Geologists study the Earth and its formations, using tools such as strip plates, hand magnifiers, dropper bottles, pennies, and hardness scales to identify minerals. Other tools like pry bars, rock hammers, and compasses are used in the field. The tools needed depend on the geologist’s questions and experience. A geologist is a scientist who studies […]
