Lake Baikal water storage How many? Three Gorges reservoir can fill 600 available in Beijing by 5900

Water storage capacity on Earth is huge, with about 1.386 billion cubic kilometers of water, and this volume accounts for only 0.128 percent of the total volume of the Earth, according to scientists study showed that the total volume of about storage on Earth 1.386 billion cubic kilometers, the total volume of the Earth is approximately 4 / 33.14 = 1.08623E + 12 cubic kilometers, that is to say the volume of water on Earth is about 0.128% by volume of the earth.

The survival of our planet has 4.5 billion years old, and life on Earth there are 3.8 billion years, and during this period, there have been countless creatures, the most representative dinosaurs and mammoths ancient times, saber-toothed tiger and so on, there are more advanced creatures later appeared, including humans.

Aerospace history strangest satellite, not an electronic device, the extraordinary role of scientist

However, the satellite also some electrical equipment and no one, is a mere dead, but then critical research scientists. May 4, 1976, a disco ball looks like a satellite was launched from Vandenberg Air Force Base, and its satellite early fifties and sixties, there is no external solar panels, but it does not bring internal any power source;

Earth is now the birth of more than 40 billion years, and in this period more than 40 billion years, the Earth above the transport countless lives, humans are now the dominant above the Earth, mankind is not content to explore the earth, but to look at the outside space, but in all, the human understanding of outer space for far more than the Earth's interior to understand much more, after all, can go to outer space observation through a telescope, but inside the Earth humans have no way to reach the depths of the earth directly through the drilling machine currently known to man is the former Soviet Union's deepest cave dug a big hole, this hole is only 12 kilometers deep, if they wish to dig deep in the earth, still need to dig 500 such a distance, so overall it inside the Earth in the end there What kind of things, we can only speculate based on.

Magnetic field over the South Pacific cracks appear, does that mean, Earth's magnetic field has begun to reverse?

There are research data show that between 7600 million years, the Earth's magnetic field reversed about 100 times the average reversal once every 50 million years or so, showing cyclical, once Earth's magnetic field has reversed over a distance of 76 years, that is to say the Earth a magnetic field reversal has entered the next cycle!

Chondrite, contains important information about the early solar system

What is chondrite? The stone has a unique structure becomes chondrules Chondrite; except H, He, and other volatile components, the chemical composition component closest to the sun. Chondrite often contain large amounts millimeter pellet. The term CHONDRITES be applied to any component of the sun close to the meteorite, type I carbonaceous chondrite although no pellets are also classified into chondrite.
