Fitting puzzle pieces together is analogous to how we study the Earth. By considering Earth as an integrated system, with many interlocking parts, we are able to understand the larger picture of global change.
The biosphere is all life on our planet. Interdisciplinary research combining biochemistry, geochemistry, biology, hydrology, and atmospheric science helps us to better understand the biosphere’s role in the Earth system and, in particular, how biogeochemical cycles affect the Earth system.
The geosphere includes the rocks and minerals on Earth – from the molten rock and heavy metals in the deep interior of the planet to the sand on beaches and peaks of mountains. Beyond these parts, the geosphere is about the processes responsible for the constant recycling of rocks on Earth.
