Soil moisture is the water that is held in the spaces between soil particles, generally in the upper 10 cm of soil; this small amount of water plays a critical role in controlling the transfer of water and heat energy between Hydrosphere, Biosphere, and Geosphere.

In some parts of the world sea levels are increasing, while decreasing in others, and remain relatively flat in a few places; for more than 20 years, NASA has been tracking the global surface topography of the ocean to understand the important role it plays in our daily lives.

No matter if you are an elementary, middle, or high school science teacher, we bet that you observe and investigate air temperatures or (their effects) with your students.  Changing air temperatures are cyclical and predictable, but also are rising beyond the normal range due to a variety of fact

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,

Snow cover and ice extent are monitored by satellite instruments measuring the reflectance of Earth's surface in various wavelengths every day. Snow and ice have a recognizable pattern of reflectance, so the satellite data can be processed to show where snow and ice are present.
