Scientists claim discovery of Zealandia a submerged continent in Pacific Ocean

Geologists have claimed discovery of new geological continent named Zealandia submerged beneath the south-west Pacific Ocean. Zealandia is around 4.5-million square km land mass and is 94% under water. Only its highest points — New Zealand and New Caledonia are visible.  Key Facts Zealandia is two-thirds the size of Australia and spreads out over 4.9-million-square Read More…

Scientists confirm existence of lost continent lies under Indian Ocean

Scientists have confirmed the existence of a “lost continent” under the Indian Ocean island of Mauritius. It is left over by the break-up of the super-continent Gondwana, which started about 200 million years ago. The discovery was based on study of Zircon, a mineral found in rocks spewed up by lava during volcanic eruptions which Read More…

Silicon identified as ‘missing element’ in Earth’s core

Scientists from Tohoku University in Japan have claimed that Silicon (Si) is the ‘missing element’ in the Earth’s core. This discovery could help us to better understand how our world formed. According to them silicon likely makes up a significant proportion of Earth’s core after its major constituents iron and nickel. It was missing element Read More…

New fault in Indian Ocean may trigger earthquakes in future: study

According to scientists, a new plate boundary may be forming on the floor of the Indian Ocean in Wharton Basin as a result of the 2012 earthquake that shook the Andaman-Sumatra region. The discovery was based on the study of seismic data recorded before, during and after the 2012 quakes and sea floor depth analysis Read More…

Scientists witness the birth of an ice cloud for the first time

US based researchers for the first time have observed the creation of ice crystals on individual atmospheric particles in the laboratory. This observation gives an unprecedented glimpse at most critical but least understood parts of the process of cold clouds formation. Key Facts Researchers had replicated heterogeneous ice nucleation process in which particle attracts water Read More…
