Scientists gauge power of mighty asteroid that shaped Earth A monster asteroid, far more massive than the one that drove the dinosaurs to extinction, punched a huge hole in the Earth's crust billions of years ago and triggered global earthquakes that sent waves of towering tsunamis across all the world's oceans. Stanford scientists studying ancient rocks in a region of East Africa known as the Barberton Greenstone have for the first time modeled the asteroid's impact and concluded that it must have been one of the most powerful events to ever shape the face of Earth. The jumbled rocks there hold clear evidence of the stuff thrown up by the asteroid's impact roughly 3.26 billion years ago, but no one has found just where the crater-forming asteroid actually hit, said Stanford geologist Donald Lowe, who has explored the jumbled rocks of the Barberton area for more than a decade.

Personal, Business, Education Here, at myHistro, we are big believers in creating and sharing meaningful content. We do not believe that casual tweets and status updates are those that define you as a person. We do believe that every person has much more than just a one side to express and recall. We have always wanted myHistro to be a place where people can complete their “actual self” by showing different sides of one's personality: from hobbies & travels to general interests and real friends. From ancestors and family trees, to experiences and education. florida/1860slavepop Powered by WorldMap florida/1860slavepop Sign in | Create Map | View Map | Help Search for geospatial data
