Precious Metals Were Brought Earth by Asteroids

According to scientists the precious metals that we see on Earth today may be largely heavenly in nature, coming from the sky billions of years ago. Back when the Earth was just forming, the materials that make up the planet were combining and differentiating into layers by weight, lighter materials floated to the surface and now make up Earth’s crust, while heavier materials such as iron sank to the planet’s interior.

Heat Coming From the Bowels of the Earth

About half of all heat coming from the bowels of the Earth, left over from the formation of planets in the solar system.Earth that has developed as the other planets in our solar system from a single dust cloud about 4.5 billion years ago, all the time from this moment is hot. Planet receives heat from two main sources: the first the decay of radioactive elements in the bowels of the Earth (such as uranium and thorium), and second it’s the heat left over from the time of formation of the planet. The researchers analyzed data collected by the KamLAND neutrino detector on the island of Honshu in Japan.

The Influence of Solar Wind to Earth

According to Group of South Korean scientists the speed of the solar wind, a stream of charged particles, emanating from the Sun, may have a direct impact on the weather, increasing the atmospheric pressure even at mid-latitudes.The speed of the solar wind can vary widely from 250 to 800 kilometers per second at the boundary of Earth’s atmosphere. Periods of rapid growth of the solar wind’s speed is usually observed during high solar activity.
