We often take the Biosphere for granted and as the climate changes, plant species and ecosystems respond by adapting, migrating or reducing their population. Why is this important? The plants of the Biosphere feed us, clothe us, absorb carbon dioxide, provide us with oxygen,
This digital badge will introduce you to Veggie, a project taking place at the Space Station Processing Facility, at Kennedy Space Center. The badge provides educators with the background information they need to incorporate this project into the classroom.
The colors on these maps show a measure of the "greenness" of Earth's landscapes. The values on these maps—ranging from -0.1 to 0.9—have no unit.
Drought conditions have affected much of the U.S. Southwest and Central Plains in recent years. But scientists now believe future droughts in the last half of this century could be the worst in the past millennium.
Identifying cause and effect relationships can help us make predictions about the function of natural systems and their impact on the world. These relationships, whether simple or complex, are vital for forecasting weather and predicting Earth events in new contexts.
The Earth's system exemplifies stability and change. Change and rates of change can be observed and quantified over very short or long periods of time and at various spatial scales (e.g., from landscape level to global processes).
Scientists are interested in learning how the vegetation (collection of plants) of an area can be used to study Earth's climate.
Students analyze historic plant growth data (i.e., peak bloom dates) of Washington, D.C.’s famous cherry blossom trees, as well as atmospheric near surface temperatures as evidence for explaining the phenomena of earlier peak blooms in our nation’s capital.
The Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) instrument aboard the Seastar satellite collected ocean data for more than a decade.
Turbulent storms churn the ocean in winter, adding nutrients to sunlit waters near the surface. Each spring this gives rise to massive blooms of phytoplankton. These microscopic plants harvest vital energy from sunlight through photosynthesis.
