Meteorites are heavy. Most meteorites are much denser than ordinary Earth rocks. The unusual weight is due to high iron content. Even stone meteorites will feel heavier in the hand than most Earth rocks. Meteorites likely traveled in space for millions of years before visiting us here on Earth.
New Mexico was at one point the leading producer of turquoise in the United States until Arizona and Nevada took the lead. Now most turquoise mining has stopped do to the quantity and question of economics. Nevada has been the major producer of Turquoise since 1930. There are about 75 to 100 different mines that have produced high amounts of turquoise ranging in the thousands to millions of dollars. Associated with some of the turquoise deposits are two other gem materials that can resemble certain colors and shades of turquoise.
Igneous rocks can form in two environments that are very different. All igneous rocks came from magma. Changing from magma to rock the magma either freezes or crystallizes. When it cools fastly the crystals are small, but when it takes a long time to cool the crystals are large. Magma can complaetely crystallize into a crystal or even a diamond.
This is one of the oldest methods of knowing when ground deformation was caused because of rising lava. We also use electronic tilt meters, this is very similar to what a carpenter uses, it has a small container filled with a liquid and a bubble (to measure the change of the slope) There are different and varied sensitivity of tilt meters, for example; you can use tilt meters with ranges from 10 to 10,000 microradians depending on the volcano and range of tilt. “A bulge on the north flank, this was caused due to a blockage at the opening at the top of the volcano. The magma formed in a chamber on the side of the volcano and it was being pushed outward because the more magma was getting forced to the side. It increased by 7 ft a day.” Earthquakes You can predict when a volcano will erupt because you get earthquakes.
Dr. Doug Stewart stated that it was because of this experiment that Lavoisier was able to conclude that, “…diamond and charcoal were made of the same element-carbon.” In nature, diamonds are formed under high pressure and deep within the earth over long phases of time. According to author R. S. Balmer et. al., “The genesis of natural diamond is believed to occur at depths of around 200 km, corresponding to pressures and temperatures of 70-80 kbar and 1400-1600°C” (3). These conditions occur naturally in a few places on earth; the first, and more abundant and likely, if formed in the lithosphere below the continental plates, and the second occurs site of a meteorite strike (Carlson, 248). Diamond-bearing rock can be transported from the lithosphere to the Earth's surface through volcanic eruptions, which form very deep within the earth.
Pebble Mine The Pebble deposit is a massive deposit of gold, copper and molybdenum, located in the headwaters of the Kvichak and Nushagak Rivers. The Pebble Mine is an idea to set up a mine at those sites and take those resources out of the ground. If built, it would be one of the largest mines ever, measuring 2 miles wide and up to 2,000 feet deep. Like all other projects like this, the Pebble Mine has many pros as well as cons. One pro of this idea is that they construction of this mine and the mine itself will create thousands of new jobs.
The two most popular methods are growing diamonds through chemical vapor distillation and also by use of heavy machinery to compress and heat carbon materials into their crystallized form. Chemical vapor distillation or CVD, is a process that uses a heated and pressurized chamber to grow a diamond in. The chamber is filled with a current of gasses (typically one carbon based and hydrogen as some) that are energized and provide conditions where diamond growth is possible by the settling of the carbon atoms inside. The other method which is known as HPHT, involves the use of heavy machinery to pound heat and pressurize raw carbon materials into diamonds. Both methods have been advanced in ways that makes it hard to distinguish between an earth made diamond and a lab created one.
limb_flare_sm.jpg (5710 bytes)Solar flares are tremendous explosions on the surface of the Sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons of TNT. They occur near sunspots, usually along the dividing line (neutral line) between areas of oppositely directed magnetic fields. The biological effect. There is a growing body of evidence that changes in the geomagnetic field affect biological systems.
It created a lot of homes for the animals that are living in the park and became big attractions for visitors all around the world. The volcano in Yosemite Park erupted and the lava cause to make igneous rocks because of the cooling and solidification of the lava. Also the lava formed other rocks like granite and tonality are all form of plutonic rock, but also referred to as granitic rocks (Yosemite National Park). Plutonic rocks are compress with five minerals (Yosemite National Park). The plutonic rocks were formed by magma and are form deep within the Earth.
Scientists predicted the yield to be four to six megatons and were shocked when Bravo produced a 15 megaton yield making it two times the expected yield. Castle Bravo was 1000 times more powerful than the bombs used on Hiroshima and Nagasaki in 1945. Despite the remarkable power, it is only the fifth largest test in history. Russia’s “tsar bomba” holds the record for the largest nuclear test which yielded 50 megatons. Castle bravo resulted in nuclear fallout which rained down on the islands and service members who were working on the operation.
