Teachers, are you looking for resources to help you engage students in data analysis related to Volcanic Eruptions? Check out this image. These data show the number of known volcanic eruptions during the Holocene epoch (about 10,000 years ago to present) at each grid point on a 1-degree-by-1-degree grid. 

Review this page to learn about the background of volcanoes and their eruptions.

In addition to the changes brought about by natural forces, it has recently become apparent that a relative newcomer to planet Earth — the human being — has become a powerful agent of environmental change.

Air quality is a measure of the pollution level in the air. Polluted air can be caused by many things. There are manmade and natural sources of emissions. 

The Earth's system is characterized by the interaction of processes that take place on molecular (very small) and planetary (very large) spatial scales, as well as on short and long time scales. Before scientists may begin their work with these data, it is important that they understand what the data are.
