The inner core is approximately 16% of the planet's volume. It is made up of iron and nickel compounds. Nobody knows for sure but the outer core is thought to consist of sulfur, iron, phosphorus, carbon and nitrogen, and silicon. The mantel is said ... upward direction. Radiation is the transfer of energy out of a substance through the excitement of gas molecules surrounding a substance. Radiation is dependent upon two things the object emitting the heat and the surrounding's ability to absorb heat. Convective geothermal systems are characterized by the natural circulation of a working fluid or water. The heated water tends to rise and the cool to sink continually circulating water throughout the ... be placed very deep in the well where only the liquid phase is present. By keeping the liquid under pressure it is possible to keep the liquid at a much higher temperature than the liquid’s normal boiling point. If the liquid is not kept under pressure, it will flash. Flashing is the process of vaporization. It requires 540 calories per gram of heat to vaporize water. The super heated ...
- 18124: Hobbes’ Leviathan: Analysis of its Impact on the Framing of our Democracy
- ... insight into these issues. Hobbes’ Leviathan: Analysis of its Impact on the Framing of our Democracy Thomas Hobbes’ Leviathan, written against the backdrop of the horrors of the English Civil War, in the mid 1600’s, is a discussion about the principles of man’s basic need for peace, unity, and security, in both nature and civilization. Essentially arguing in favor of a sovereign monarchy, Hobbes writes in such a manner as to present these basic principles so they could ... whole body. But it is more than just this that Hobbes says makes up man. Man has, or at least should have sense, imagination, speech, and reason. Sense is an instrument for conception in man’s mind. Without the senses, man cannot see the “Representation or Appearance of quality” (85). Imagination is the remembering of things once perceived by the senses, and the ability to compound different memories into one, ...

The planet's specis are dying off-more exactly, we're killing them -at the staggering rate of 100,000 per year, a figure that works out to almost 2000 species per weak, 300 per day, 10 per ... every 6 minutes. We're trashing the planet, washing away the topsoil, paving over our farmlands, systematically deforesting our wildernesses, decimating the biota, and ultimately killing ourselves. The world is getting progressively poorer, and it's all because of populating, or more precisely, over-population. There's a finite store of resources on our pale blue dot, spaceship Earth, our small and fragile tiny planet, and we're fast apporaching it's ultimate carrying capacity. The limits to growth are finally ...

- 18127: Atomic Bomb 9
- ... self-sustained chain reaction takes place and causes the atomic explosion. This type of atomic bomb was used on Nagasaki, and given the nickname Fat Man after Winston Churchill. The blast from an atomic bomb s explosion will last for only one-half to one second, but in this amount of time a great deal of damage is done. A fireball is created by the blast, which consists mainly of dust ... The dynamic pressure creates winds, which have the power to blow down trees. The blast pressure and fireball together only last for approximately eleven seconds, but because it contains fifty percent of the atomic bomb s latent energy a great deal of destruction occurs. In Hiroshima, the blast from the atomic bomb was measured to be about four and a half to six and seven tenths tons of pressure per square ... when people and glass fragments were projected through the air. By combining the results of the static overpressure and the dynamic pressure one can begin to see what damage was caused by the atomic bomb s blast. The thermal radiation produced by an atomic bomb explosion will account for thirty-five percent of the atomic bomb s damage. Thermal radiation can come in one of three forms: ultraviolet radiation, visible ...

- 18130: Continental Drift
- Continental Drift Continental drift is the theory that the positions of the earth's continents have changed a lot through geologic time. The German meteorologist Alfred Wegener proposed the first comprehensive theory of continental drift in 1912, on the basis of the way the continents fit together on the ... there was one great big continent, or supercontinent, called Pangaea. Pangaea split into two big landmasses, Laurasia and Gondwanaland. The present continents separated in the next geologic era, the Mesozoic. In this process, the Earth's rotation caused horizontal alterations in the granite continents floating on the sea of the basaltic ocean floors. The frictional drag along the leading edges of the drifting continents created mountains. Wegener's theory met controversy until 1954, when British geophysicists seeking to explain the phenomenon of polar wandering revived it. Since then, the modern theory of Plate Tectonics has evolved from and replaced Wegener's original ...
