Explanation / Answer
1.- 157 no. of Earth-observing satellites currenly
2.- The satellite Polar-Orbiting Suomi was lunched on 28 october,2011 for the duration of 5 years byBall aerospace.
3.- The primary function of NASA’s Aqua satellite is to study precipiation ,evaporation,cycle of water, soil moisture, sea ice, land ice and snow cover on land and ice.
4.-
5.-A- the Atacama Desert is located in South America and it is plateau.
B- It get 15mm/year rain, but in Arica and Lquique it is 1 to 3 mm/yr.
6.- Antartica's cold temperature is an average of -63 C whereas north polar's temperature is about -1 to -2 C.
7.- A-Atlantic , Pacific and Indian oceans aree surrounding Antartic Ocean.
B- the massive current that circles the continent is called Antartic Circumpolar Current(ACC) or called West Wind Drift.
8.- the Jason satellite was jointly operated by NASA of United States of America and by CNES of France.
9.- Jason can see through ocean and atmosphere especially helpfull in study of EL Nino and La Nino.
10.-
11.-
12.-
13.- Phytoplanktons are similar to terrestrial plants and they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton float in the upper part of the ocean, where sunlight penetrates the water. Phytoplanktons require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.
14.- the LANDSAT satellite records the images of earth which are applicable in agriculture, cartography, geology, forestry, regional planning, surveillance and education.
15.-
16.- NASA's Aqua satellite and Terra satellite are called the twin of Aqua. it gives the entire view of our earth.
