Snow Gauge
2009-07-06 18:17:29

A snow gauge is an instrument used in meteorology to gather and measure the amount of solid precipitation (as opposed to liquid precipitation that is measured by a rain gauge) over a period of time. A snow gauge has two parts: the copper catchment container and the funnel shaped gauge itself. The actual gauge is mounted on a pipe that is about 4 ft. 11 in. high. The gauge itself is about 20.25...

Drainage Divide
2009-07-06 18:07:31

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political...

Water Cycle
2009-07-06 17:58:20

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun...

Meltwater
2009-07-06 17:15:30

Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as...

Rain
2009-07-04 16:31:47

Rain is a type of liquid precipitation. It is defined as condensation of atmospheric water vapor that forms into drops that become heavy enough to fall, and often making it to the surface. Rain is the primary source of most of the fresh water in the world. Rain provides suitable conditions for diverse ecosystems, water for power sources and for crop irrigation. Not all rain reaches the surface....

Clear Ice
2009-07-04 15:43:10

Clear Ice refers to a solid precipitation that forms when air temperature is between 32 degrees and 27 degrees Fahrenheit and there is a presence of super-cooled, large drops of water (from freezing fog). A rapid build up and slow dispersing of latent heat of fusion favors conditions for the formation of the transparent ice. A similar phenomenon occurs when freezing rain or drizzle hit's a...

Swallow-tailed Gull Creagrus furcatus
2009-06-04 22:59:50

The Swallow-tailed Gull (Creagrus furcatus) is a species of seabird of the gull family. It is found in the equatorial seas where it spends most of its time hunting on the open ocean. Its main breeding grounds is on the cliffs of the larger Galápagos Islands, and on some of the smaller islands. It is typically found along the eastern islands where the water is warmer. It is also found in...

Phyllorhiza punctata
2009-06-03 12:34:11

The Phyllorhiza punctata is a specific species of jellyfish that is an inhabitant of the southwestern Pacific. It has been found on Sunset Beach in North Carolina and Bogue Sound which is further north along the North Carolina Coast. It has also been found in the Caribbean and the Gulf of Mexico and spotted in Hawaii but not confirmed. The Phyllorhiza punctata has numerous names such as the...

Danube Crayfish

The Danube Crayfish or Galician Crayfish (Astacus leptodactylus), is a species of crayfish native to eastern Europe. It can be distinguished most easily from the commoner European or broad-fingered crayfish (Astacus astacus) by the relatively thinner "fingers" of the claws. Photo Copyright and Credit

Signal Crayfish
2008-05-04 22:26:21

The Signal Crayfish (Pacifastacus leniusculus), is an American crayfish indigenous to the western United States. Signal Crayfish were introduced in Swedish rivers and lakes to replace the native crayfish species there that were nearly exterminated from the crayfish plague that devastated the European crayfish stocks. This species has also been introduced to Japan and a number of other countries...

Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
