12 interesting facts about the planet Earth
Such different colors of the sky
Polar lights appear when charged particles that emanate from the Sun reach the magnetic field of our planet and are destroyed in the upper layers of the atmosphere near the poles. Particles become more active in the period of maximum activity of the Sun, which occurs cyclically every 11 years. Near the southern pole of the aurora, people are less likely to observe because they rarely appear near the coast of Antarctica.There are other planets like ours
Scientists suggest that in the universe there are many planets similar to ours. Evidence was found that planets like Earth rotate around distant stars. For example, a planet called Kepler 22-b rotates around the star at the same distance from it as our planet from the Sun, and this indicates that on this planet there can be favorable conditions for life. Although there is life on these planets - while still a matter of controversy in the scientific world.Who was getting to the South Pole?
The first man who successfully crossed the Antarctic Desert to reach the South Pole was the Norwegian Rual Amundsen. He and 4 others with the help of sleigh, which pulled the dogs, reached the Pole in December 1911. Amundsen said that he was lucky thanks to careful planning.The dryest place
The dryest place on the planet, where a person sometimes appears - the Atacama Desert in Chile and Peru. In the middle of this desert there are places where rain has never been recorded. Although in the Dry Valleys of Antarctica rain has not been observed for millions of years.Open spaces
People who sometimes like to be alone, are advised to go to Greenland. This island has the lowest population density on Earth. So in 2010 on the area of 2166086 square kilometers there were only 56534 people. Most of the inhabitants of Greenland can be found off the coast.The most populous city
Do not like densely populated cities? Then we advise you not to go to Manila. This city - the capital of the Philippines - is the most populous city on the planet, where a relatively small piece of land is forced to hide most of the country's population. According to the population census in 2007, there were 1660714 people at 38.55 square kilometers!The smallest mammal
On Earth, lives a large number of tiny creatures, the body of some of them consists of only one cell. But the smallest animal-mammal can be called the squirrel bat. This vulnerable species of bats lives in southeast Asia. The mouse reaches a length of about 3-3.3 centimeters and weighs about 2 grams. This bat can compete with a dwarf multiboot, which is about the same size.The largest organisms
The largest organisms on the planet can be called, oddly enough, mushrooms. Most of the fungal organism is hidden underground. In 1992, scientists reported in the journal Nature that the spill in Oregon occupied an area of 0.89 hectares.Breathable giants
When we try to remember the largest living creatures on the planet, the minds come from whales and elephants. The giant sequoia "General Sherman" is by far the largest tree on the planet that grows in the Sequoia National Park, California. The tree trunk contains 1486.6 cubic meters of material.The largest swimming pool
The largest ocean basin on the planet is the Pacific Ocean basin, which covers an area of 155 million square kilometers and contains more than half of all water on Earth. It is so large that all the continents could fit in the same area.Inhabited coastlines
Coastlines occupy only 20 percent of the US territory, not including Alaska, and are home to over 50 percent of Americans, that is, most prefer to live by the sea.
The Third Planet
12.Our native planet Earth is the third planet from the Sun and the only planet of the solar system where conditions exist, an atmosphere with free oxygen is maintained, there are oceans of liquid water on the surface and, most importantly, there is life on it.
