A exacting example of a scientific discipline that draws upon multiple natural sciences is environmental science. This field studies the interactions of physical, chemical and biological components of the environment, with a exacting regard to the effect of human activities and the impact on biodiversity and sustainability. This science also draws upon knowledge from other fields such as economics, law and social sciences.
A comparable discipline is oceanography, as it draws upon a alike breadth of scientific disciplines. Oceanography is sub-categorized into additional specialized cross-displines, such as physical oceanography and marine biology. As the marine ecosystem is very big and diverse, marine biology is further divided into many subfields, including specializations in particular species.

Alongside this established usage, the phrase natural sciences is also sometimes used more narrowly to refer to its everyday usage, that is, related to natural history. In this sense "natural sciences" may refer to the biology and perhaps also the earth sciences, as illustrious from the physical sciences, including astronomy, physics, and chemistry.
Within the natural sciences, the word hard science is sometimes used to describe those sub-fields that rely on experimental, quantifiable data or the scientific method and focus on accuracy and objectivity. These generally include physics, chemistry and many of the sub-fields of biology. By contrast, soft science is often used to explain the scientific fields that are more reliant on qualitative research, including the social sciences.
There is some explore, collectivelly known as graphism thesis, that indicates that natural science relies on graphs more than soft sciences and mathematics do.
