 EPOD - a service of USRA

The Earth Science Picture of the Day (EPOD) highlights the diverse processes
and phenomena which shape our planet and our lives. EPOD will collect and
archive photos, imagery, graphics, and artwork with short explanatory
captions and links exemplifying features within the Earth system. The
community is invited to contribute digital imagery, short captions and

   Happy Red Rose Day! Each weekend we present a notable item from our
   archives. This EPOD was originally published May 12, 2013.

   Summary Authors:  Alejandro Jaramillo;  Jim Foster
   The photo above showing a red  rose draped in  dewdrops was taken
   in  Medellin, Colombia. When air at a constant  atmospheric
   pressure is cooled below its  dew point, typically in the early
   morning hours, moisture  condenses not only on blades of grass and
   windshields but on all nearly all exposed surfaces. In fact, many
   plants, and even some animals, rely on dew and  fog as a valuable
   source of water.
   The  dipole charge on every  water molecule attracts them to each
   other -- positive to negative and negative to positive. Water drops are
   more or less spherical because of this  electrostatic attraction and
    cohesion. Photo taken on May 3, 2012.
   Photo details: SONY NEX-5N camera; 54 mm focal length; f/5 aperture;
   1/100 sec. exposure; ISO 200.
