Mercury is a very rocky planet, its surface is like the Earths moon. It lacks an atmosphere, but experiences extreme temperature anywhere between 90 to 700 Kelvin. It is geologically dead, however it does have a magnetic field which is generated inside the planets core, it magnetic field is only around one 500th of Earths. Mercury is dominated by its core, it has a radius of around 1800 Kilometres and has a less dense mantle which has a depth of 500-600 kilometres. 60 percent of Mercury's mass in

1. Schumann discovered Schumann resonance. He discovered how the Earth produces a fixed frequency of 7.83 Hz. Dr. Ankermueller stumbled upon the book which Schumann resonance was recorded in. Together Ankermueller, one of his students and Schumann made the connection of how human resonance(alpha waves) is almost exactly the same as the Earth's resonance(Schumann resonance). Meaning that we and most if not all life on Earth is in tune with the frequency of the planet. 2. They found that the students

occurred that forever changed everything; the “Day of Awakening” as it is called now in the present… It was a strange day for sure, as both the USSR and the USA were set on launching what would be their landing missions to the Moon, despite trying to get there before the other they ended up switching the same day and time; as the rockets left the Earth’s atmosphere everything went silent with the ships and before long they crashed back into the Earth with somehow no one being injured in them.

The video in its varied forms tells us how the earth’s resources are depleting day in and day out and the reasons for the same are we humans. Destroyers of all!! As known by all, in the beginning the earth was a mass of nothingness. But gradually, over a period of years life began to form from the bacteria that fed off the earth’s heat. Life altered the atmosphere. It got its energy from the

created the Clean Energy Act. The CEA serve to reduce our dependence on fossil fuel. Other governments have imposed a tax on carbon emission to encourage using clean energy. Global warming is no longer fiction, scientific studies have proved that earth is undergoing a period of rapid change. The Intergovernmental Panel on Climate Change (IPCC) claims that the average global temperature has increase .74C. Our high dependence on fossil fuels as source of energy has raised the atmospheric content of
