ES Picture of the Day 12 2021
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

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.
