new discoveries in geography

Explanation:
Life In The Bottom Of The Lightless Sea
In 1977, Oceanographer Robert Ballard was commissioned by the National Geographic Society to use the Alvin, a submersible vehicle that can take scientists 4,500 meters down into the ocean, to research hydrothermal vents located deep in the Pacific Ocean bed, and discovered life forms that did not need photosynthesis to live. This was proof that there are still life-forms on earth that we have not yet discovered.
Dinosaurs Used To Live In Antarctica
Scientists found numerous sets of fossilized dinosaur bones in the mid-1980s until the early 1990s on frozen lands of Antarctica. According to a New York Times article, the reason that was possible was that at the time of the dinosaurs, the earth was 50 degrees hotter and the Antarctica plate was then located in the southwest Pacific Ocean.
A Meteorite Containing Possible Life From Mars
Because of its largely undisturbed vast landscape, it is relatively easy to find meteorites in Antarctica. A group of scientists from Stanford University and NASA found a fist-sized meteorite in 1996, which came from Mars, and landed on earth around 13,000 years ago. This meteorite had what looked to be fossilized microbial life-forms from the Red Planet.
The Discovery Of A New World
On August 3, 1492, Christopher Columbus set sail in search of a new route to the Asian continent. He knew the earth was round but had no idea of how big it actually was. By October, he and his crew landed on a small island which he named San Salvador. In the next few years, more explorations to the new world were made, discovering the Americas and Caribbean Islands.
