The expression "biosphere" was authored by geologist Eduard Suess in 1875, which he characterized as the spot on Earth's surface where life dwells. While the idea has a land beginning, it means that the impact of both Charles Darwin and Matthew F. Maury on the Earth sciences. The biosphere's environmental setting originates from the 1920s (see Vladimir I. Vernadsky), going before the 1935 presentation of the expression "environment" by Sir Arthur Tansley (see biology history). Vernadsky characterized environment as the study of the biosphere. It is an interdisciplinary idea for incorporating stargazing, geophysics, meteorology, biogeography, development, topography, geochemistry, hydrology and, as a rule, all life and Earth sciences.
