What do paleontologist use to determine the age of rocks?
Geologists determine the age of rocks through a process called radiocarbon dating, a process which "peers inside [the] atoms" of the rocks.
For more detailed information about how radiocarbon dating works, check out the related link which is a website with lab instructions for groups in a class.
How does one select an entrepeneurial activity to be preserved?
To select an entrepreneurial activity to be preserved, consider its impact on society, cultural significance, historical relevance, and potential for innovation. Look for activities that have made a positive contribution to the community or economy and have the potential to inspire future entrepreneurs. Additionally, prioritize activities that align with sustainable practices and can be leveraged for long-term benefit.
What condition in the past produced a mold fossil?
A mold fossil is formed when an organism decays and leaves an impression in the surrounding sediment or rock. Over time, the impression fills with minerals, creating a cast of the organism's shape.
What kingdom do fossils belong in?
Fossils can belong to any kingdom. It all depends on what the fossil is.
Why are fossil fules important to humans?
Humans rely on them because they are the most effective and economically viable fuel source currently available.
They have discovered other energy sources and how to utilize them (such as hydrogen, natural gas, bio-fuel[ethanol], and solar) but these sources have not been found to be impractical because as of this moment humans have not been able to produce produce these forms of energy at an output that would be at a high enough level above what they put in (ie lets say 1 liter of hydrogen can generate 270 BTU but lets say it costs 200 BTU to generate, this example may not be true, it is just a hypothetical situation. Fossil fuels usually only require half of the energy they put out to gain, so 100 BTU per gallon of gas costs 50 BTU to extract)
The reliance of humans on fossil fuels is very great at this point in there history, but evidence suggests that this will change in the next few decades should they survive the collapse.
Where are dinosaur fossils found in Arizona?
Dinosaur fossils have been found in various parts of Arizona, including sites near Tucson, the Petrified Forest National Park, and the Grand Canyon. Some notable dinosaur fossils found in Arizona include those of Dilophosaurus and Sonorasaurus.
Where was spinosaurus fossil found?
Spinosaurus fossils have been found in North Africa, specifically in countries like Morocco, Egypt, and Algeria. The first significant discovery was made in Egypt in the early 20th century. Subsequent findings in Morocco have provided more insights into the dinosaur's size and lifestyle.
How fossils can be used to determine the absolute and relative age of a sedimentary rock layer?
Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.
What is an important characteristic of an index fossil-?
a. pex: it might have lived in a very wide geographic region
Where did the phrase She sold sea shells by the sea shore originate?
There was a 11 year old boy who stuttered a lot and he met a hot girl at a beach one day and when he described her, he used that phrase and didn't mess up but when the person repeated it he FAILED!!!
How fossil tell the age of earth?
Fossils can only provide an estimation of the age of the formation surrounding it. One scientific method of dating a fossil involves analysing the isotopes surrounding it. Another method involves looking at the layers of rock in which it is embedded.
How old would a fossil be if it had only one eight of its original carbon-14 content remaining?
The half-life of carbon-14 is about 5,730 years. If a fossil has only one-eighth of its original carbon-14 content remaining, it would be roughly 3 half-lives old. So, the fossil would be around 17,190 years old.
What are the fallacies of fossil dating?
One of the biggest fallacies of fossil dating is that they use the rock layer to help determine the age of the fossils, but the fossils are also used to help determine the age of the rock layer.
Where was the croosbow first found?
The crossbow was first found in ancient China. It was developed during the 5th century BC and played a significant role in military warfare in various cultures around the world.
What rocks would most likely be found on the ocean floor shale granite basalt or marble?
Basalt would most likely be found on the ocean floor, as it is a common igneous rock formed from the solidification of lava. Shale, granite, and marble are all less likely to be found on the ocean floor, as they are sedimentary and metamorphic rocks that are not typically formed in marine environments.
Who is credited with finding the famous fossil of sue?
The famous fossil of Sue, the Tyrannosaurus rex, was found by paleontologist Sue Hendrickson in 1990 in South Dakota. This fossil is one of the most complete and well-preserved T. rex skeletons ever discovered.
Why was the fossil Woolly Rhino so well preserved?
The woolly rhinoceros (Coelodonta antiquitatis) is an extinct species of rhinoceros that was common throughout Europe and Asia during the Pleistocene epoch and survived the last glacial period. The genus name Coelodonta means "cavity tooth". The woolly rhinoceros was a member of the Pleistocene megafauna.
What fossils are in the mirage tower in Pokémon Emerald?
In Pokémon Emerald, the Mirage Tower contains two fossils: Root Fossil and Claw Fossil. Players can choose one fossil to revive into either Lileep (from the Root Fossil) or Anorith (from the Claw Fossil) at the Devon Corporation in Rustboro City.
How do you mark off the area to be searched?
You can mark off the area to be searched using caution tape, cones, or temporary barriers. Make sure the boundaries are clearly visible to those conducting the search.
How do fossils help explain the theories of evolution?
Fossils give us a lot of information about species which used to exist on Earth but which are now extinct. With this information we can see in greater detail how species have evolved over time.
Trilobites are ancient fossils commonly found in dome-shaped rocks composed of thin layers of sediment. These creatures have a hard exoskeleton that can be well-preserved in sedimentary rocks.
Is the formation of fossils a common event?
No. For fossil formation to take place a series of fortunate events must occur. If any part of the series is missing we will never see the fossil! In fact, fossilization is a fairly rare occurrence. Nature tends toward recycling. That includes just about everything from plants and animals to rocks and minerals.
Are dinosaur fossils found in Europe and Asia?
Yes, dinosaur fossils have been found in Europe and Asia. In Europe, notable dinosaur discoveries have been made in countries like the UK, France, Spain, and Romania. In Asia, countries such as China, Mongolia, and India have also yielded significant dinosaur fossil finds.
What is the definition for fossil?
Fossils are the preserved remains or impressions of living organisms that lived in the past. They can be found in rocks or sediments and provide important information about the history of life on Earth.
What life form that lived during the Paleozoic period is an important index fossil?
The life forms that lived during the Paleozoic are Permian, the Carboniferous, (both the Mississippian and the Pennsylvanian), the Devonian,the Silurian, the Ordovician, the Cambrian, and the Precambrian. The Paleozoic Era lasted from 570 to 225 Million Years Ago. Complex forms of life appear. During this 345 million year period, plants and animals underwent rapid evolution.
The Paleozoic era lasted about 345 million years. It includes the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods. Index fossils of the first half of the Paleozoic era are those of invertebrates, such as trilobites, graptolites, and crinoids. Remains of plants and such vertebrates as fish and reptiles make up the index fossils of the second half of this era.
