- 10451: The Noble Gases
- ... by Morris W. Travers. Traces of it are found in natural gas, hot springs and volcanoes but most of it is in the atmosphere. It is used for incandescent lights and it is used in high speed photography. Xenon is the first noble to form compounds with another element. It is very heavy and extremely rare. Sir Walter Ramsey and Morris W. Travers discovered it. It is found in mineral springs ...
- 10452: Titanium
- ... metal combines with oxygen at red heat, and with chorine at 550 degrees Celsius. Titanium when a metal, is considered to be physiologically inert. Pure titanium dioxide is kind of clear and has an extremely high index of refraction with an optical dispersion higher then diamond. The location of titanium on the Periodic Chart is in the series of sub groups called transition elements. Other then the fact that transition elements ...
- 10453: Observed Distribution of South American Relief Features
- ... Europe 5-10 million years later. Convection cells that propel the plates produce Earths surface dynamics such as the features seen on the relief map of South America. Earths crust juts out as high as the sky along with the deep valleys that are being produced from the crashing and spreading of these plates. The amazing landscape features are a result of centuries of change within earth. BIBLIOGRAPHY Bird ...
- 10454: Human Cloning
- ... humans and no publicly recognized funding agency is ready to finance experiments that involve the cloning of humans (Kestenbaum, p 315). The potential exists but without a dedicated effort and full support from those in high places, the issue of human cloning will remain a popular debate for the foreseeable future. The ethics surrounding the issue of cloning are many, and it will be many years before a final decision on ...
- 10455: Drumlin Formation By Catastrophic Flooding
- ... of lakes such as the lower Great Lakes, and the Finger Lakes of New York, and the many other large lakes along the border of the Canadian Shield in Canada. Whereas the drumlins occur on high plateau in western New York, and other drumlinized areas, these are incised by deep wide valleys, some of which contain lakes. Lake basins such as Lake Ontario were evidently excavated subsequent to the drumlin formation ...
- 10456: How Toxic Waste Affects Canadas Natural Environment
- ... oceans. People figured that the oceans were so huge that garbage would just "disappear", and sink to the bottom. Well, they were wrong. Chemicals have turned up in dead whale bodies and dead fish in high enough concentrations to kill people. Medical wastes such as used needles and vials of blood (some carrying the AIDS virus) have washed up along the Atlantic coast and in one of the Great Lakes. Mutated ...
- 10457: Cellular Diffusion
- ... concentration of a substance. This brings into play the processes of diffusion, osmosis, and active transport, all of which involve only small simple molecules. Diffusion is the movement of a substance from a region of high concentration, to a region of low concentration of that substance. In other words, a movement down the concentration gradient. Osmosis is very similar to diffusion, however it involves the concentration of water. Osmosis, like diffusion ...
- 10458: Possibility of Terraforming One of Earth's Neighboring Planets
- ... s energy, have governed the rate of species progression and facilitation of life. The following diagram illustrates the balance of the atmospheric gases required for aerobic respiration: CO2 + H2O-(CH2O) + O2 (CH2O) + O2 Photosynthesis Respiration High Energy Quantum CO2 + H2O Low Energy Quantum Light Heat This formula for life took nearly 4 billion years to occur on Earth. The stoicheometrically correct concentrations of these photosynthetic elements slowly came into existence due ...
- 10459: UFOs and Alien Life
- ... electricity, heat, and sickness during sightings so they see something usual which they consider a UFO. Captain Thomas was flying a plane when he reported a UFO to the Highway Patrol. He was flying too high so he crashed. He then had a lack of oxygen and so he died. Later it was concluded that he was chasing a secret weather balloon. In 1947, "something hit the ground in Corona, NM ...
- 10460: The Landsats Satellites
- ... NOAA). The EROS Data Center (EDC) has managed the Landsat data archive for more then two decades. It provides an impressive collection of information about the Earths land surface. The SPOT satellites carry two High-Resolution Visible (HRV) sensors capturing visible and near-infrared radiance data with multispectral and panchromatic scanning capabilities. The multispectral mode captures data in three bands in the following spectral ranges: .50-.59, .61-.68 and ...
