For those of us who live on the earth, maybe you think we have very understood about the earth facts, but not necessarily, there are some facts you might not know. Perhaps a glimpse not occurred to you, here are some earth facts that you probably do not know.
1. Whether in one day it will always be 24 hours?
At 1000 years ago, one day on Earth only 18 hours a day, from day to day more and slow the rotation of the earth and in one day now is 24 hours, according to calculations of scientists that someday in the future, in one day on earth will to 960 hours!
2. How much surface area of the earth?
Earth’s surface area is 510.1 million square kilometers.
3. How vast desert on earth?
Approximately one third of the earth is a desert area, if man does not restrict the behavior of individuals, then the desert-sand will be more widespread. Sahara Desert in North Africa is the largest desert in the world, is 23 times the cubic feet of fresh water stored in the earth, nearly half are within half a mile near the earth’s surface. On the surface of Mars there are also lots of water, but, until now the water is detected in the form of solids, no one knows for sure how much actual water content found there.
4. Where on earth region vulnerable earthquake and volcanic eruptions?
Most of the earthquakes and volcanoes occur at 12 border points of the earth plates, and a little more they move on the surface of the earth. However, one of the most active plate is the Pacific plate, the border area surrounding the plate these frequent earthquakes and volcanic eruptions, because it is also called seismic and volcanic regions of the Pacific Ocean, from Japan to Alaska to South America, coverage area This is very broad.
5. Is the earth’s core is solid?
According to the news that the earth’s core is a solid part, however, because the temperature is too high so around the center of the earth has melted, we never got to the center of the earth, so scientists are also unable to learn with certainty and accuracy. Recently there are scientists who put forward a concept that was bold and quite attractive, which makes a hole with a drill and then inserting a detector to investigate more about the inside of the earth.
6. What is the fastest wind speed on the surface of the earth?
Wind speed “normal” the most rapid in the earth’s surface reaches 372 km / h, this is a record that was recorded on April 12, 1934 in Washington Mountain state of New Hampshire, USA. However, in a tornado that occurred in Oklahoma in May 1995 ago, the fastest wind speed is detected researchers reached 513 km / hour, and as a comparison, the wind on the planet Neptune’s fastest to reach 1448 km/ hour.
7. How colorful fireworks which were formed?
Fireworks are played at the feast of varied patterns and colors, it is the color that is created from minerals in the earth. Strontium can produce garnet, copper produces blue, sodium produces the color yellow, iron filings and charcoal produces golden yellow sparks, flashes of bright light and loud sounds coming from aluminum powder.
8. What is the total gold produced in the world?
In total gold produced in the world more of 193 thousand tons (metric tons), if all this gold dumped into one, can accumulate a four-square arrangement of buildings as high as 7 floors. Africa and the United States are the two gold-producing countries, South Africa produces 5300 tons of gold / year, and the United States produces more than 3200 tons / year.
9. Where is the coldest place on earth and the heat?
You are mistaken if you think that the valley of death in California, USA, is the hottest place in the world, in one year during a relatively long time there is very hot, however, recorded the warmest place was in an area in Libya, on 13 September 1922, temperatures there reached 57.8 degrees Celsius, this is the highest value in the temperature record in history. On July 10, 1913, the highest temperature in Death Valley California, U.S., reaches 54 degrees Celsius. Areas with the lowest temperature in the world are in central east Antarctica, on July 21, 1983 the temperature reached 89 degrees below zero Celsius.
10. How does thunder happen?
If you think caused by lightning, it is also true, however, the proper assumption is that the air temperature around the lightning rose dramatically, approximately 5 times that the temperature of the sun. The sudden heating causes the air velocity to expand more rapidly than the velocity of sound, this will compress the air in the vicinity and form a shock wave, so we could hear the thunder.
10 things above are a few things of facts about Earth that you may not know in advance. This article reveals only a fraction of the facts about Earth. There are millions of interesting facts about the earth that has not been revealed until now.
