View Resource Mass-Wasting and Mass-Wasting Processes

Mass-Wasting is defined as the down slope movement of rock and regolith near the Earth's surface mainly due to the force of gravity. Mass-wasting is an important part of the erosional process, as it moves material from higher elevations to lower elevations where transporting agents like streams and glaciers can then pick up the material and move it to even lower elevations. Mass-wasting...

View Resource Practical Analysis of Nutritional Data

This online textbook, created by faculty members at Tulane University, provides information on the statistical analysis of nutritional data. Techniques covered include data cleaning, descriptive statistics, histograms, graphics, scatterplots, outlier identification, regression and correlation, confounding, and interactions. Each chapter includes exercises with real data and self-tests to be...

View Resource Slope Stability, Triggering Events, Mass Wasting Events

This article, authored by Professor Stephen A. Nelson of Tulane University, focuses on many aspects of slope stability. Some of these factors include: the role of water, troublesome earth materials, triggering events, and assessing and mitigating mass-wasting hazards. The article is filled with detailed diagrams along with accompanying textual descriptions that make a cohesive piece easily...

View Resource Deformation of Rock

Professor Stephen Nelson of Tulane University created this resource on rock deformation. A synopsis and overview of principles associated with physical rock deformation is provided. Nelson also briefly touches on stress/strain, folds, deformation (Ducile/Brittle), faulting, and the earth's crust.

View Resource Tulane University: Radiometric Dating

The fourth website, developed by Professor Stephen A. Nelson at Tulane University, provides a detailed mathematical explanation of the principles of radiometric dating. The site is divided into sections which include: Principles of Radiometric Dating; The Rb/Sr System; The U, Th, Pb System; and The Age of the Earth. Other dating methods are covered briefly as well, such as potassium argon...
