Asked in Geology, Rocks and Minerals Why doesn't radiometric dating produce exact results? No because it impossible to show the exact result.

Radiometric dating does not usually work with sedimentary rocks because they.? You can't date all minerals using the radiometric dating method because not all minerals have radioactive. Because sedimentary rocks contain fragments of many rocks that could be different ages, radiometric dating is less useful for dating sedimentary . Feb 01,   You can use radiometric dating on sedimentary rocks but it will not give you a precise age. You would need many samples and it would give you a round-about depositional age range. For example if you dated a sediment that had samples at million years old, Ma, and Ga, you know that the original rock the sediment came from is that old.

Asked in Nuclear Physics How is the half-life used in radiometric dating? Radiometric dating often called radioactive dating is a technique used to date materials, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

apologise, but, opinion

Carbon 14 dating is the best known example of radiometric dating, but there are many others. Another example of radiometric dating is the dating of the age of geological formations on earth.

The oldest known rocks on the earth that have been analyzed, have been dated back some 4. Asked in Geology, Rocks and Minerals Why are sedimentary rocks important to relative dating?

Asked in Geology Scientists use radiometric dating to determine the absolute age of a rock Why is radiometric dating useful for this task?

How Carbon Dating Works

Radioactive isotopes decay at a constant rate. Carbon 14 dating is one tpye of radiometric dating. It is used for destermiing the age of samples of one-living entities.

Asked in Geology, Earth Sciences, Sedimentary Rock Suppose a lava flow was found between two sedimentary rock layers How could you use the lava flow to learn about the ages of the sedimentary rock layers? Because of geologic events such as plate tectonics and volcanism, suitable material for radiometric dating, such as volcanic tuff, solidified lava, and igneous intrusions have been found as layers on, in, and cut through layers of sedimentary rock.

You will not

Intrusions are always younger than the rock body they penetrate, meaning that the sedimentary rock in which intrusions are found will be older than a radiometrically dated sample of the intrusion. Lava flows and volcanic ash which form layers in rock will be younger than the rock below and older than the rock above.

topic, very

The solidified intrusions and lava flows can be dated with radiometric techniques. The radiometric dating of suitable rocks i.

Radiometric dating doesn't usually work with sedimentary rocks because they . - Mar 23,   Because the elements used for dating need to be re-set by volcanism. Radioactive elements decay at a certain constant rate and this is the basis of radiometric dating. But, the decay elements need to be set, much like you would re-set a stop watch for a runner, to ensure an accurate measurement. When minerals get subducted into the Earth and come back as .

Asked in Scientists How do you tell how old a fossil is by the rock layer? How does the image relate to the text? The protest against the salt tax continued. The Salt March and protests that followed it brought worldwide attention to the Indian Independence movement and British cruelty.

Sedimentary rocks cannot be dated directly using radiometric dating, which is based on the idea that when rocks are in liquid form, their radiometric clock resets. This technique is generally used to date igneous and metamorphic rock, which are rocks that were once melted due to extreme heat and pressure. to date a sedimentary rock layer between two igneous rock units, geologists use radiometric dating and assume that the sedimentary layer's age is between the absolute ages of the two igneous units. a half-life of a radioactive substance is the amount of time needed for one half of to decay into a stable isotope. please help me!!! Radiometric dating does not usually work with sedimentary rocks because they . are too old to be accurately dated form too quickly to be accurately dated never contain particles of radioactive isotopes form from many older rock particles.

Why was it called a Salt March? What were 60, Indians arrested for? In response, all of the elected Indian officials resigned from the government.

In a speech entitled, "Do or Die," given on August 8,Gandhi urged the masses to act as an independent nation and not to follow the orders of the British.

How Do Scientists Determine the Age of Dinosaur Bones?

His call found support among a large number of Indians, including revolutionaries who did not support Gandhi's philosophy of non-violence. Almost the entire Congress leadership, both at the national and local levels, was put into confinement less than twenty-four hours after Gandhi's speech, and the greater number of the Congress leaders spent the rest of the war in jail.

Despite lack of direct leadership, large-scale protests and demonstrations were held all over the country.

The British responded with mass detentions, making overarrests. The Quit India Movement died down in a few months, but other groups of Indians started to rebel against the British. A group of Indian soldiers that once fought for the British, switched sides during WWII to fight with the Japanese in an attempt to invade India from the Southeast, defeat the British, and declare India independent.

They were unsuccessful, but the attempt showed how deeply Indians disliked British rule. In addition, in sailors in the Royal Indian Navy revolted against the British, refusing to work, carrying on violent protests, and in some instances taking over ships.

The pressure from the Quit India Movement, recognition that the armed forces were opposed to British rule, and the drain on resources from WWII and the recovery from that war, led the British to give up their control of India. What was the goal of the Quit India Movement?

Radiometric dating doesnt usually work with sedimentary rocks because

Last month, on her way out of the hospital after working the evening shift, Amanda was abducted by a man with a gun and taken to a remote area and sexually assaulted. This is what archaeologists use to determine the age of human-made artifacts.

But carbon dating won't work on dinosaur bones.

right! like this

The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old. Dinosaur bones, on the other hand, are millions of years old - some fossils are billions of years old.

To determine the ages of these specimens, scientists need an isotope with a very long half-life. Some of the isotopes used for this purpose are uranium, uranium and potassiumeach of which has a half-life of more than a million years.

apologise, but, opinion

Unfortunately, these elements don't exist in dinosaur fossils themselves. Each of them typically exists in igneous rock, or rock made from cooled magma. Fossils, however, form in sedimentary rock - sediment quickly covers a dinosaur's body, and the sediment and the bones gradually turn into rock. But this sediment doesn't typically include the necessary isotopes in measurable amounts. Fossils can't form in the igneous rock that usually does contain the isotopes.

not necessary try

The extreme temperatures of the magma would just destroy the bones.
