Earth science is a well-established area of knowledge that studies the Earth from various scientific perspectives. Earth scientists often employ investigative approaches that more properly belong to the disciplines of biology, chemistry, physical geography, physics, and mathematics. Earth science can also study the nature phenomena of our planet from either reductionist or holistic vantage points. Some sub-disciplines of earth science include: environmental science, geology, geophysics, glaciology, hydrology, meteorology, climatology, oceanography, physical geography, and soil science.
