Fossils
This category is for questions about the bones, fragments, imprints, and other remainders from a different time. The questions and answer you will find here are history set in stone -- our past, immortalized in solid rock. You will also be able to find questions pertaining to the locations of these fossils, how you might identify them, and how they were formed.

It depends what you mean by resource. They are a resource of collectable material used by paleontologists and some hobbyists, but in the normal run of things they are no more a resource than any other rock.
What does fossil evidence show about Earth's climate?
The fossil evidence shows that the Earth's climate before had high levels of carbon dioxide. The plants that evolved consumed this carbon dioxide out of the air and formed oxygen, coal, limestone, and other fuels.
The herb form of gelsemium has historically been used for migraines resulting from excessive cerebral blood flow, severe wheezing attacks of asthma, insomnia , and nerve pain, particularly trigeminal neuralgia.
What are some examples of alternative to fossil fuels?
There are no alternatives to fossil fuels. Fossil fuels were formed by life trapping sunlight falling on Earth over time periods of hundreds of millions of years. There is no realistic alternative for this source (amount) of energy. Once these fuels are used up all we will have is a little nuclear energy and access to the day to day energy currently falling on the planet. This will not be enough to sustain our civilization. The only hope is progress with nuclear fusion energy research.
How can you tell if he really loves meand if after all the things that happened between us?
Well if a guy really loves u he will stay with you na matter what and wont beileve anyone else and hell hold ur hand when walking and tell all ur friends bout u and no matter what happens if he truly loves u he still will Well if a guy really loves u he will stay with you na matter what and wont beileve anyone else and hell hold ur hand when walking and tell all ur friends bout u and no matter what happens if he truly loves u he still will
How can scientists understand what the relevant age of a fossil is?
There are layers of earth that are deposited over time and based on where a fossil is in the layers a scientist can understand what the age of the fossil is relevant to another fossil in a different layer of earth. The law of superposition says that new sediment is deposited on top of old sediment so, the sediment in the bottom layer is the oldest and the sediment at the top is the youngest.
Because of this the fossils in the bottom layer are the oldest and the fossils near the top are the youngest. Say you have 10 layers of rock, and the top layer is number 1 (the youngest) and the bottom layer is number 10 (the oldest). Even if a scientist can't tell exactly how old a fossil is if they know it is in a layer deeper than another fossil they know it is older than that fossil so, a fossil from layer 9 is older than a fossil from layer 5 which is also older than a fossil from layer 3. This is relative age.
If we take it a step further... If a scientist knows that the fossil in layer 4 is 65 million years old than we not only know the fossils in layer 5-10 are older than the one in layer 4, but that they are all older than 65 million years old. So, the fossils in layer 1-3 would be less than 65 million years old. Scientists can know how old a specific fossil is sometimes based on whether or not it is an index fossil (a fossil that only occurred during a very small, specific interval of time), or if it is possible to carbon date it or something in the same layer.
What dinosaur fossils will you find in the smithsonian institute?
The very first dinosaur fossil was theDystrophaeus viaemalae it was collected and donated in 1859 by J. S. Newberry. Dinosaur footprints from the Lower Jurassic in the Connecticut Valley, was donated in 1861. Allosaurus, Stegosaurus, Camptosaurus, Ceratosaurus, Triceratops, and Edmontosaurus. Diplodocus, Camarasaurus, and Brachyceratops, Stegosaurus, and Thescelosaurus. The first complete and fully mounted dinosaurs were the Edmontosaurus (1903) and then the Triceratops (1905). These were later joined by the Ceratosaurus (1910), Camptosaurus (1911), two individuals of Stegosaurus(1913 and 1918), Thescelosaurus (1914), Brachyceratops (1920), and Diplodocus (1931). The Diplodocus was huge it was infact 70 feet long and was the only exhibit where visitors were allowed to walk underneath it. Another specimen was much later added the Gorgosaurus and this was completed in 1960. In 1963 walking under the Diplodocus was stopped but now there was a Sauropod Femur that they were allowed to touch. In 1981 the hall was reopened with a new exhibit a full mount of an Allosaurus.
How would it feel to become a petrified fossil?
You would not know anything about it, as you would have been dead a long time before.
Which of these is defined as impressions left in rocks by living things that died a long time ag?
An impression of something left in rocks by living things that died long ago is referred to as a fossil. Archeologists have uncovered fossils of single celled organisms that lived millions of years ago.
Depends if you are talking about animals or plants.
Plants: male gametophytes (pollen grains) are found in the anther(microsprangium), female ovules are found in the ovary (megasporangium).
Animals: Generally male found in the testes and female gametophyes in the ovaries
What happened in Dartmouth College v New Hampshire?
( Dartmouth College was given a charter by king George III but New Hampshire wanted to take it away.) This was a Supreme Court case that stated the land grants given to people or organizations act as a legal contract and give that owner rights and privileges to that land. Marshall ruled in favor of college
Scientists first need to determine the age of the fossils through radiometric dating or other methods. They also need to identify the species to understand its evolutionary relationships. Additionally, studying the geological context in which the fossils were found can provide valuable information for placing them in the ancestral timeline of dogs.
Why does the very existence of a fossil imply catastrophic burial?
In order for a fossil to form, it must be buried quickly before it decays and its bones are scattered or decomposed. As a rule, conditions for a quick burial occur only during catastrophic events, such as volcanic eruptions, landslides, mudflows, or floods.
What is the second most important source after fossil fules contributing to india's energy need is?
hydropower
Why is it difficult for an organisms living in the rain forest to become a fossil?
Things tend to decompose in a warm and moist environment. Mummification/fossilization typically happens in either very cold climates, very dry climates, or both. Since the rain forest is both warm and damp, decomposition typically happens very quickly.
Which environment is best for a petunia?
Petunias are very tough in most temperate climates and are especially tolerant of sunny and drier conditions. They should not be grown in overly rich soil as they will become sappy and weak. Neither do they particularly like very windy conditions. A sunny position in average garden soil will suit them well.
Which theory explains why kangaroo fossils have been found in Africa?
The theory of continental drift explains how kangaroo fossils could have been found in Africa, as it suggests that continents were once connected as a single landmass called Pangaea. Over time, the continents drifted apart to their current positions, carrying fossils with them. This helps to explain how species like kangaroos, which are native to Australia, could have ended up in Africa in the past.
