SATELLITE CAUSE THE LIGHT POLLUTION

   Light pollution causes due to the excessive light during night time. This light reflection will reduce the darkness of the night sky .Today 90% of stars which can be seen with naked eye are invisible. Doctors have proved that this light pollution will affect the health of human. The production of melanin occurs in darkness of night will affected by brightness of light . Also affect the eyesight of human by LED light. 


   Most of the nocturnal animal will distracted from moonlight or confused by manmade light. Some of the birds use dark as their orient to migrate which were fail due the high intensity of light in urban areas. Due to the light the day time get into the night and night time will reduced. Thus it leads to habitat changes in the ecosystem and leads to extinction of nocturnal animals.


   In lake, when the natural night light is reduced then zooplankton will not eat the algae. This leads to increase in the growth of bacteria which reduce the oxygen level in lake. Thus affect the water ecosystem. The glow in the sky the image of dim object will be foggy and unclear. This affect the astronomer study at fluorescent object such as their chemical composition ,temperature and speed at which they move. Astronomer often attempt to takes spectra of object and fail to do so.
   Number of objects are orbit the earth will increase the brightness of the night sky by more than 10%. We can see the satellite in sky for few minutes while they revolve the earth that looks like star in the sky. If the object move with blinking light it is plane while the satellite will not produce light of its own . Light formation on satellite due to sunlight reflection as solar rays will power the satellites. Highly reflective solar panel making it brightest. To overcome this light pollution the mega consolation satellites are developed.

WHY ATLANTIC AND PACIFIC OCEAN ARE NOT MIXED?

Nearly 72% of the earth is filled with water and it is present with different names- oceans, seas, rivers. Why are they named differently? There are five oceans namely Artic ocean, Atlantic Ocean, Pacific Ocean, Indian ocean and Antarctic ocean . All the oceans are different in their physical and biological character called ocean clines. When we look at the Atlantic and Pacific Ocean junction, they do not mix. Is there any invisible Wall in between them? Many scientists have conducted research to solve this mystery. The Atlantic and Pacific Ocean have different chemical composition. The salinity of the water in the Atlantic Ocean is five times more than the Pacific Ocean. The density of water is also different, so even marine animals in Atlantic Ocean will not go to the Pacific Ocean. They cannot survive in other oceans. Atlantic and Pacific Ocean meet at Cape Horn. The narrow straight line formed by the water bodies is called Drake Strait. The Pacific Ocean is ...

6 Unknown Amazing Spots In The World

  Rotura is known as the world’s most remarkable geothermal wonderland, with shooting geysers and bubbling mud pools. While you indulge in relaxation, don’t forget to learn about the fascinating culture of Maori within your side trips.   Marvel at the Pangong Tso Lake in Ladakh, Himalayas is the most famous lake in India, this lake isn’t exactly a secret place, but it’s still relatively unvisited. Stretching out for about 160 km, this saltwater lake contains the highest amount of saltwater in the world.   The Salar de Uyuni (Salar de Tunupa) in Bolivia is a salt flat that extends to 10,582 square kilometres is considered to be the world’s largest salt flat in the world. Tucked away in Potosi, southwest of Bolivia, this is one of the most beautiful unknown places in the world. Formed as a result of the prehistoric lakes within its surroundings.   Dive into the blue lake at Jiuzhaigou National Park (China) is get a glimpse of this 1375-metre-lon...

The Chemical Lake

 Spotted Lake or Lake khiluk in Canada is richly concentrated with various minerals. It contains dense deposits of magnesium sulfate, calcium, and sodium sulfates. It also contains high concentrations of eight other minerals and lower amounts of silver and titanium. Most of the water in the lake evaporates over the summer, revealing colorful mineral deposits. Large ‘spots’ on the lake appear and are colored according to the mineral composition and seasonal amount of precipitation. Magnesium sulfate, which crystallizes in the summer, is a major contributor to spot color.  Originally known to the First Nations of the Okanagan Valley (Native American Tribe) as Khiluk, Spotted Lake was for centuries and remains revered as a sacred site thought to provide therapeutic waters. It is the most mineralized lake in the world. Each spot holds a different cure due to the unique chemical content found within each puddle. Lake Khiluk is considered a saline endorheic alkali lake. The Okanag...
