Nuclear power stations work in fossil fuel-burning stations‚ except that a "chain reaction" inside a nuclear reactor makes the heat instead.The reactor uses Uranium rods as fuel‚ and the heat is generated by nuclear fission: neutrons smash into the nucleus of the uranium atoms‚ which split roughly in half and release energy in the form of heat.Carbon dioxide gas or water is pumped through the reactor to take the heat away‚ this then heats water to make steam.The steam drives which drivegenerators

The Moon - Introduction Its hard to imagine the history of Earth without our Moon. For as long as man walked this Earth‚ the Moon served as "lesser light for the night" and faithful time-piece. The phases of the Moon were used to help guide the Harvest‚ or help determine the time of the river floods. How our Moon came to existence is still under speculation. There are several possible scenarios: Fission Theory - the Earth spinning so fast during early formation that a piece broke off forming

Cosmos – an alternative name for the universe Meridian – a half circle extending from your horizon (altitude 0) due south through your zenith to your horizon due north. Zenith – the point directly overhead‚ which has an altitude of 90 degrees. Latitude –The angular north-south distance between Earth’s equator and a location on Earth’s surface. Longitude – The angular east-west distance between the prime meridian (which passes through Greenwich) and a location on Earth’s surface. Speed – The

as smooth as the naked eye saw it to be. The surface of the moon was actually uneven‚ rough‚ and full of cavities. He looked at Jupiter through his telescope and saw 3 stars aligned with the planet. The next night when he looked at them again‚ their positions had changed. He had discovered the moons of Jupiter. The scientist studied the heliocentric model and the planets movements for months. He saw that Venus had phases like the moon‚ so he thought it must go around the sun. The Church thought

The paper will derscribe how the earth and its atmosphere evolved with the help of other bodies. Which includes a discription of the formation of the bodies that plays a role in the evolution of earth. Also‚ a discription of the earth‚ sun‚ moon‚ planets‚ and other bodies motions according to Copernicus‚ Kepler‚ and Gallileo discoveries. Evolution: Earth and Its Atmosphere
