Dr. Dalia B. Kirschbaum is a Research Physical Scientist in the Hydrological Sciences Lab at NASA Goddard Space Flight Center, Greenbelt, MD. Learn how she uses mathematics to investigate the interaction between the Hydrosphere & Geosphere.

The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. 

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

Students categorize causes, effects, and responses to volcanic hazards through an Earth system perspective. They use remotely sensed images to examine the visible effects of the eruption of Mount St. Helens in 1980 and identify a buffer zone for safer locations for development.

Students use scale to determine the area of volcanic deposits following the March 3, 2015 eruption of Chile's Mount Villarrica stratovolcano, one of the country's most active volcanoes.

Soil Conservation Technicians collect and manage survey data for conservation, develop a plan to implement conservation actions, and supervise fieldwork.  Their work starts with developing physical resource plans and documents on the history of the land. Technicians survey, layout, and section off the site.  They assist the landowner in selecting, installing, and maintaining a variety of measures that conserve and improve the soil, plant, water, marsh, wildlife and recreational resources of the land.

Botanists research plant characteristics like their physiological processes, their evolutionary history, resistance to disease, relationships to other parts of the Biosphere and within the Earth System. 

Many botanists work in different locations; some may work indoors in laboratories and offices conducting experiments while others may work in agriculture and spend much of their time outdoors.  Some botanists may also discover new plant species and share their learning with the public through tours and events.

 Air, Water, Land, & Life: A Global Perspective

Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.
