Earth’s surface process and subsurface tectonic activity combine in the formation and distribution of sediments and landforms.
Integrated across time, the resulting sedimentary rocks hold the story of past conditions different than today’s. From young sediments, we learn about environmental activities prior to significant human impact or about the impacts of extreme weather events. From sedimentary rocks and landforms, we learn about previous climate states, earlier geographic arrangements of river drainage systems, and past tectonic activity.
Sedimentary rocks hold resources needed for today and the future. Some of those resources are the solid rock itself. Yet many types of resources are fluids within the pore spaces, including fresh water, heat-transporting geothermal fluids, and lithium-rich brines. An understanding of the large scale organization of the pores contributes to discovering, extracting, and carefully managing these vital resources.
