Please consider using this graphic organizer to help students analyze the processes and components of Earth System phenomena.

NASA Worldview is a free online visualization tool that is a great launchpad for learners who are new (or

The purpose of this activity is to have students use an Earth Systems perspective to identify the various causes associated with changes to Earth's forests as they review Landsat imagery of site locations from around the world.

The Sahara Desert is a near-uninterrupted brown band of sand and scrub across the northern third of Africa. The Amazon rain forest is a dense green mass of humid jungle that covers northeast South America.

Learn how Landsat data are used to detect changes in land use. This video describes how the data are interpreted and gives examples of changes in forests from different insects and differences due to land management.

This investigation introduces students to the significant environmental changes occurring around the world. The investigation uses NASA satellite images of Brazil to illustrate deforestation as one type of environmental change.

The Earth is constantly changing. Some of this change occurs slowly over many millennia, and some occurs relatively rapidly over the decades.
