Why are human brains the biggest? We would like to inform you that human brains are not the biggest compared to other animals.
The meteorite that hit the Earth around 50,000 years ago in the place near Winslow, State of Arizona, has formed a largest on the Earth cavity called Barringer Meteor Crater. The diameter of the crater measures 0.75 miles (1.2 kilometers) with the depth in 590 feet (180 meters). Crater walls are at the average slop of 40-50 degree, though in some places vertical or nearly vertical walls are observed. The Barringer Meteor Crater is one of the unique places on the Earth where geologic details are preserved. While craters normally form a round shape, the Barringer Crater looks more like a quadrangle. The Barringer Crater is considered as a treasured scientific site, not only for students and post-graduate researchers, but also for scientists researching the surfaces of Moon and Mars.
Crater has also become a training ground for astronauts and robot hardware testing. It acts as a learning laboratory for planetary geologists who are investigating impact cratered terrains on other planets. Moreover, Crater helps to interpret the observations of Mars by providing researchers with the information on how water produces gullies and otherwise erodes the crater. Lastly, the Crater is providing an on-the-spot opportunity for evaluating the design of traverses and geologic station activities on the moon, Mars and other exploration destinations. Besides the research site that the Crater acts as, there are also many questions about the Crater itself. According to David Kring, a senior staff scientist and geologist at the Lunar and Planetary Institute in Houston, an important remaining problem is that the trajectory of the impacting iron asteroid and the damage it caused to Earth’s crust beneath the crater floor remain a mystery. And finally, the Barringer Meteor Crater acts as a place of attraction for tourists – during last year it had more than 225,000 visitors. Scientists are looking forward to preserve the Crater in its best condition and to continue researches in the Crater’s area for getting more answers to the questions from the space, universe past and future.
