Aa Aa Aa Biogeochemical cycles describe pathways by which chemical elements move through both biotic (the biosphere) and abiotic compartments (the atmosphere, hydrosphere, and lithosphere ...

Some use their knowledge about Earth processes such as volcanoes, earthquakes, and hurricanes to plan communities that will not expose people to these dangerous events. Earth sciences can include the ...

"I think it's still considered one of the great unsolved problems in geophysics today." Earth's lithosphere — its crust and rigid upper mantle — is split into roughly 15 constantly-moving plates.

The atmosphere interacts closely with the rest of the Earth system – including the biosphere, hydrosphere, cryosphere, and lithosphere – as well as ... emission control policies, land-use change, as ...

The processes that form continental crust from the denser basaltic rocks of the upper mantle may make the lower lithosphere denser ... that occurs throughout Earth's crust, they argue.

The long-term goal of my work is to develop a molecular-level understanding of the geochemical processes that couple the lithosphere, hydrosophere and biosphere. To this end, I use synchrotron-based ...
