Earth sciences are the fields of study concerned with the solid Earth, its waters, and the air that envelops it. They include the geologic, hydrologic, and atmospheric sciences with the broad aim of understanding Earth's present features and past evolution and using this knowledge to benefit humankind. Earth science or geoscience includes all fields of natural science related to planet Earth. This is a branch of science dealing with the physical and chemical constitution of Earth and its atmosphere. Earth science can be considered to be a branch of planetary science, but with a much older history.
Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres, namely biosphere, hydrosphere, atmosphere, and geosphere.

The four basic areas of Earth Science study are: geology, meteorology, oceanography and astronomy.
The study of Earth science includes many different fields, including geology, meteorology, oceanography, and astronomy. Each type of Earth scientist investigates the processes and materials of the Earth. Like other scientists, Earth scientists ask questions.
Earth Science covers a multitude of subdisciplines, including, but not limited to: geophysics, geobiology, geochemistry, hydrogeology, limnology, mineral physics, mineralogy, palaeontology, petrology, rock and mineral magnetism, seismology, and structural geology and tectonics.
Career prospects in Geology, Earth Science and Environmental Science are very good, both in related fields (reaching far beyond the typical 'oil and gas' remit) and in alternative roles as graduates are considered highly skilled and have a wide range of transferable skills.
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
