About this guide

Soil erosion happens naturally and through human actions. In this activity, students will explore how an oil spill changed Louisiana’s coastline, and they will look for examples of landscape features that were created by erosion and examples of human-caused erosion in their area.

This Guide Includes:

Why soils in marshes matter

Students will answer questions about the online Science News article “The Deepwater Horizon oil spill ruined long-term shore stability,” which explains how damage to plants and soils is causing coastal marshes to retreat in parts of Louisiana. A version of the article, “Shores still reeling from 2010 oil spill,” appears in the March 25, 2023 issue of Science News.

Cascading effects of erosion

Students will discuss a disastrous event that led to erosion and use the event to contextualize the impact of erosion on humans and the ways humans increase and decrease erosion. Learning Outcomes: Determining examples of erosion and its positive and negative impacts on humans and analyzing an example of a human-induced ecosystem disruption and understanding how it caused erosion in the ecosystem over time.

How Erosion Alters the Landscape

When wind and water move, they don’t move alone — they take parts of the land with them. In this activity, students will investigate how water carries sediments from one location to another via erosion and will explore how this natural process can alter the landscape.
