A geologist is: a person versed in the science of geology.

Geoscience is the study of the composition, structure, and other physical aspects of the Earth. Geoscientists (people versed in geoscience) study the Earth’s geologic past and present by using sophisticated instruments to analyze the composition of earth, rock, and water.

Geologists study the composition, processes, and history of the Earth. They try to find out how rocks were formed and what has happened to them since their formation. They also study the evolution of life by analyzing plant and animal fossils.

Geophysicists use the principles of physics, mathematics, and chemistry to study not only the Earth’s surface, but also its internal composition, ground and surface waters, atmosphere, oceans, and magnetic, electrical, and gravitational forces.

Geoscientists usually study and work in one of several closely related fields of geoscience which are listed below.

Fields of study in the geosciences are: Biology, Paleontology, Geology, Mineralogy, Climatology, Paleoclimatology, Biogeography, Geomicrobiology, Oceanography, Marine Biology, Atmospheric Chemistry, Vulcanology, Geophysics, and Environmental Science.

Biology is the study of plants and animals.

Paleontology studies fossil life forms.

Geology is the science and study of the solid and liquid matter that constitutes the Earth. The field of geology encompasses the study of the composition, structure, physical properties, dynamics, and history of Earth materials, and the processes by which they are formed, moved, and changed.

Mineralogy is the study of the earth's minerals.

Climatology is the study of weather patterns over periods of time and how humans may impact climate.

Paleoclimatology poses theories and studies prehistoric weather systems.

Biogeography evaluates the location of species on Earth, and studies how geographic changes in the earth impact plant and animal populations.
 
Geomicrobiology evaluates tiny organisms or parts of organisms and their interaction with things that are not organic, like rocks and minerals.

Oceanography and Marine Biology evaluate living systems in the oceans, fossil records of previous ocean life, rocks and minerals and how they form in ocean settings. Subsets of these two fields also map the ocean floor, which isn't complete as of yet.

Atmospheric chemistry examines the chemical values that compose the earth's atmosphere.

Vulcanology is the study of volcanoes.

Geophysics is a more instrument-oriented discipline that investigates the Earth's internal structure and processes by studying seismic waves and variations in our planet's magnetic and gravitational fields as well as its rotation.

Environmental Science focuses on the near-surface realm of the Earth and the way humans interact with that environment. Environmental scientists study natural hazards, water availability and quality, waste management and the use of Earth's limited resources.
