Exploring Geoheritage From Space

 Great images of geoheritage sites can be found everywhere.  But no one holding a camera on Earth can “back away” far enough to get the extraordinary perspective captured by NASA satellites. In celebration of Earth Science Week 2016, NASA's Earth Observatory has created a special collection of images and articles showcasing geoheritage sites in America’s National Parks.

Temperature and Precipitation Connections

No matter where we are on Earth, we can observe changes in vegetation. Some changes are drastic, such as going from dormant to full growth during a temperate winter.

Vegetative growth is dependent on both surface temperature (which influences soil temperature) and precipitation (which influences soil moisture). Together these environmental variables help determine the beginning, duration, and end of the growing season; the latter marked by leaf senescence, when leaves of deciduous trees die and turn colors.
