Change Matters Viewer and Aral Sea

Joseph Kky introduces the Change Matters Viewer by Esri, a tool that uses USGS data to analyze geographical changes such as coastal shifts and urban development. The video focuses on the Aral Sea, showing its shrinkage from 1975 to 2000 and the subsequent environmental and social impacts. The tool allows users to explore these changes and their consequences, providing a rich resource for geography and environmental studies classes.

What is the primary purpose of the Change Matters Viewer?

• To predict future climate changes

• To analyze geographical changes using satellite imagery

• To simulate urban development

• To create 3D models of landscapes

Which data source is used by the Change Matters Viewer?

• USGS

• NASA

• NOAA

• ESA

What significant change occurred to the Aral Sea between 1975 and 2000?

• It expanded significantly
