The Atlantic Ocean's Sargasso Sea was named after the Sargassum seaweed, which floats en masse on the surface there. Although it was formerly thought to cover the entirety of the Sargasso Sea, making navigation impossible, it has since been found to occur only in drifts. The historic incidents of sailing ships being trapped there are now considered due to the often calm winds of the horse latitudes.Created by: Lynn Desmondgeographic names riddles »average 60% Black SeaBlack Sea1259Red SeaRed Sea1081Yellow SeaYellow Sea737Sargasso SeaSargasso Sea4756 Which Scandinavian capital is not a seaport?All Scandinavian capitals are seaports.

Launched June 10, 2011, Aquarius is NASA’s first satellite instrument specifically designed to study the salt content of ocean surface waters. The complete first year dataset of NASA's Aquarius instrument reveals seasonal changes in the Amazon River's plume. Depending on the prevailing currents, the river's freshwater outflow heads east toward Africa or bends up north to the Caribbean.Created by: globalquiz.orgoceans riddles »very hard 38% water temperaturewater temperature3145sea currents speedsea currents speed1197water salinitywater salinity3585sea depthsea depth1293 What sea is that?Black Sea.

When a piece of iceberg ice melts, it makes a fizzing sound called "Bergie Seltzer". This sound is made when the water-ice interface reaches compressed air bubbles trapped in the ice. As this happens, each bubble bursts, making a 'popping' sound. The bubbles contain air trapped in snow layers very early in the history of the ice, that eventually got buried to a given depth (up to several kilometers) and pressurized as it transformed into firn then to glacial ice.Created by: globalquiz.orgice riddles »very hard 35% a cracking noisea cracking noise2246a fizza fizz1693a roara roar377a whispera whisper501 This photo has been taken at seaglass beach in Hawai'i.

A number of rivers from both countries flow into the gulf. As a result, a salinity gradient exists from north to south. In the south the water is the normal brackish water of the Baltic Sea, but in the north, the salinity is so low, that one can no longer taste the salt in the water and many freshwater fish thrive in it.Created by: globalquiz.orgBaltic Sea riddles »very hard 35% between Finland and Russiabetween Finland and Russia2732between Sweden and Finlandbetween Sweden and Finland3028between Sweden and Denmarkbetween Sweden and Denmark1434between Finland and Estoniabetween Finland and Estonia1432 Which landlocked country has the largest navy?Bolivia.
