Rocks - body, water, process, Earth, type, chemical, form, carbon, air
Rocks can move through the rock cycle along other paths, but uplift or burial, weathering, and changes in temperature and pressure are the primary causes of changes in rocks from one type to another. this web site really helped me!! 34 Zoe WJun 8, 2009 @ 3:15 pmIt is really helpful and can be eaasily understood but some diagrams would also be really helpful 35 sudharsanJul 9, 2009 @ 1:13 pmthis informs with pictures gives a detailed account on rocks
is number one in kinds of dinosaurs found, though the single best place in numbers of species found is Dinosaur Provincial Park in Alberta, Canada, where some 37 kinds of dinosaurs have been found. By measuring how much of these minerals have broken down we can date such a volcanic rock to within 100,000 years of when it was made, even if it was many millions of years ago
Dinosaur - Conservapedia
Creation scientists point out that evolutionists are frequently coming out with new theories to explain the supposed extinction of the dinosaurs, and that those theories are laden with false assumptions. Descriptions of dragons are widespread and match descriptions of dinosaurs, showing that dragons were real creatures and were actually very likely dinosaurs
In these situations, the only possibility of fossilization is if a fish or other swimming animal dies in oxygen-rich waters above, sinks down into the stagnant muddy bottom, and is buried by sediments. The body is usually exposed to air and water with a lot of oxygen, so it decomposes rapidly.The animal is likely to be fossilized only if it is buried soon after it dies (or when it is buried alive!)
MICROFOSSILS
Pollen and spores are very common microfossils but they require difficult extraction techniques using dangerous acids and high powered microscopes to see them. For examples, fish scales, teeth, and bones are common in marine fine grained rocks, and small teeth and bones of terrestrial vertebrates can be found in nonmarine rocks
Interesting Facts About Diamonds: You are a diamond expert if you know all of these! Large teeth and rear-placed fins make Phareodus encaustus well suited for catching and eating other fish. Volcanoes in what is now Yellowstone to the north and the San Juan volcanic field to the south produced occasional ash clouds that dropped thin layers of volcanic ash into the calm lake waters
Using the overlapping age ranges of multiple fossils, it is possible to determine the relative age of the fossil species (i.e., the relative interval of time during which that fossil species occurred). Just as the magnetic needle in a compass will point toward magnetic north, small magnetic minerals that occur naturally in rocks point toward magnetic north, approximately parallel to the Earth's magnetic field
FireRed and LeafGreen Fossils are obtained the same way as in Generation I, while Ruby, Sapphire, and Emerald Fossils may be revived by a scientist in the Devon Corporation building in Rustboro City. After defeating GhetsisBW or IrisB2W2, Fossils of previous generations will be given out by a Worker in Twist Mountain, with one being given out per day
Dating Fossils in the Rocks - National Geographic Education
What is one technique that scientists use to date the fossils they find? Show Answer Potassium-argon dating is a form of isotopic dating commonly used in archaeology. The volcanic material in tuff is well-suited for radiometric dating, which uses known decay rates for specific unstable isotopes to determine the age of the rock that contains that isotope
The fossil has the same shape as the original object, but is chemically more like a rock! Some of the original hydroxy-apatite (a major bone consitiuent) remains, although it is saturated with silica (rock). During the fossilization process, the original atoms are replaced by new minerals, so a fossil doesn't have the same color (or chemical composition) as the original object
Identifying Unknown Fossils (by their shape). Kentucky Geological Survey
Fern leaf fossils generally have a central ridge or elongate furrow, with tin lines or veins arching away from the ridge, similar to modern fern leaves. Circle shapes Small circular fossils (less than a few centimeters in diameter) Crinoid columnals are generally small circular fossils, a centimeter or less in width
Fossil and Fossilization - examples, body, used, water, process, Earth, plants, type, form
The term also is used to describe the fossil fuels (oil, coal, petroleum, and natural gas) that have been formed from the remains of ancient plants and animals. it help me keep up in my science class 8 jakeFeb 6, 2010 @ 10:10 amGreat information and declarification on fossils! Very helpful! 9 BeccaMay 4, 2010 @ 9:21 pmWhat is needed for an organism to be fossilized? I'm not so sure if you have already answered this, and if you have, could please make it a little clearer
This interactive activity adapted from the University of California Museum of Paleontology explores the kinds of things we can learn from several types of fossils that scientists study. They look along hillsides and in other areas where uplift and erosion have occurred, potentially exposing previously buried fossils.Large concentrations of fossils in a geographic area are called fossil troves or lagerstatten, a German word meaning "lode places" or "mother lode." Lagerstatten offer scientists a more complete record of the diversity and ecology of ancient communities than any single fossil can on its own
Many scientists have contributed and continue to contribute to the refinement of the geologic time scale as they study the fossils and the rocks, and the chemical and physical properties of the materials of which Earth is made. Notice how the shape of the posterior (rear) end of these clams becomes more rounded in the younger species, and the area where the two shells are held together (ligamental cavity) gets larger
In what type of rock are fossils most likely to be found : Igneous, Metamorphic or Sedimentary ? - Homework Help - eNotes.com
Therefore sedimentary rocks, either because of their location and the fact that they do not come from any volcanic activity, are more likely to remain the same and therefore whatever fossil that will be imprinted in it will undoubtedly do it easier in such a type of unchanging rock. Metamorphic rocks are like igneous rocks in that they have mixed with other rocks, have been crushed and mixed and also have been affected by extreme temperatures
Found in a wide range of environments, including beaches, oceans, sand bars, dunes, rivers, deltas, deserts and flood plains, sandstone contains fossils of creatures such as trilobytes, brachiopods, crustaceans, bryozoans and plants. They form faster than shale, limestone and sandstone and are under more pressure from fast-moving waves, so they are not as likely to incorporate fossils
This may be because the meat-eaters walked in muddy areas (where footprints are more likely to leave a good impression and fossilize) more frequently than the plant-eaters). rex's bumpy skin imprint, confirming that it had a "lightly pebbled skin." Muscles, Tendons, Organs, and Blood Vessels - These are extremely rare because these soft tissues usually decay before fossilization takes place
Shale often breaks into flakes when you hold it in you hand and is usually gray, although red, brown and black variations exist depending on the other minerals in the mixture. For obvious reasons, this process of slow accumulation is much more conducive to the preservation of animal and plant remains than the hot and violent processes that shape harder types of rock like metamorphic and igneous rock
