View Resource Focus on Sedimentary Environments: The study of depositional processes and environments at scales from the landscape to the microscope

This page serves as an entrance to the short virtual field trips developed for the FILTER project, which "seeks to educate the tertiary education community in the use of digital images and related metadata for learning and teaching purposes". The field trips may be used individually or in combination as parts of learning resources for particular courses. Each virtual field trip is a 'one-stop...

View Resource Coastal Geological Materials

Ocean basins are filled with loose sediments, which are the products of erosion. This sediment originates inland and is fed into oceans by rivers. Debris from cliffs and other coastal landforms provides additional sediment volume, as do skeletons, shells, teeth of marine organisms, ash from volcanoes, and even asteroids. This interactive feature shows how these different parent materials...

View Resource Sands

In this activity from Hagerstown Community College, students examine sand samples from various locations around the world. Using a hand lens and dissecting microscope, students will compare the size, shape, and color of the grains that make up the different sand samples, as well as looking for fossils, gems, and other minerals that sand often contains. This lesson includes activity directions as...

View Resource Evidence of Climate Change over the Last 10,000 Years from the Sediments of Lakes in the Upper Mississippi Basin

This United States Geological Society (USGS) fact sheet discusses paleoecological records derived from sediments in the upper Midwestern US (e.g. Minnesota). The paleoecological record was derived from varved (seasonally-laminated) sediment cores, geochemical data, and pollen.

View Resource Ocean Cores

This University of Arizona course website features an outline to interpreting ocean cores as they relate to past environmental conditions (e.g. sedimentation rates, climate, etc.). The outline includes figures and information about sedimentation, the history of interpreting ocean cores, how proxies in ocean cores reveal past climate, and use of oxygen isotopes to infer past climate. Key terms...
