What to methods are used to determine the age of a rock or fossil?
There are two methods used to determine the age of a rock or fossil. The first is carbon dating and the second is radiometric dating.
Can cockroach live in high concentration of carbon dioxide?
Cockroaches cannot withstand high concentrations of carbon dioxide. One of the most widely used methods used for extinguishing cockroaches are coarbon dioxide bombs.
The carbon-14 method of dating differs from the potassium-argon and the uranium-lead methods of dating by using what?
The carbon-14 dating method differs by using the decay of carbon-14 isotopes to determine the age of organic materials up to around 50,000 years old, while potassium-argon and uranium-lead methods are used for dating older rocks and minerals. Carbon-14 dating is primarily used for relatively recent materials, while potassium-argon and uranium-lead methods are used for dating geological samples millions to billions of years old.
What are the methods used to find out about the past?
Methods used to find out about the past include historical research using primary sources such as documents and artifacts, archaeology to study physical remains, carbon dating for dating organic materials, and oral history by interviewing people who have knowledge of past events.
How is carbon dating used to determine the age of fossils?
Assuming the word is 'date'; their stratigraphy - their position in the sedimentary sequence, will indicate which are older. [Assuming the fossil bed has not been overturned by earth movements.] Otherwise, various radiometric methods might be used to measure the age, but these are relatively more expensive.
What is a scientist who uses carbon-14 dating actually measuring?
A scientist who uses carbon-14 dating is measuring the amount of carbon-14 present in a sample. Carbon-14 is a radioactive isotope of carbon that decays over time, allowing scientists to determine the age of organic materials.

Which isotope is used to date ancient artifacts such as fossils?
The main isotope used for determining the age of artifacts in archaeology is carbon 14, however there are many others.Other radiometric methods (methods based on the decay rates of radioactive isotopes) include:Potassium-Argon dating - Based on the decay of potassium 40Uranium Series dating - Based on the decay of several isotopes, including Uranium 238 (also used in fission track dating), Uranium 235, Thorium 230 and Protactinium 231.Lead 210 dating - Based (unsuprisingly) on the decay of Lead 210.A climate based method, based on the "Oxygen Isotope timescale" can be used to broadly date things and uses ratios of Oxygen 18 to Oxygen 16.
What methods are used to study distant past?
Methods used to study the distant past include carbon dating, which measures the decay of radioactive carbon isotopes in organic materials, dendrochronology, which analyzes tree ring patterns to date archaeological sites, and stratigraphy, which examines the layers of sediment or rock to determine the relative age of artifacts. Additionally, analysis of artifacts, such as pottery, tools, and artwork, can provide insights into ancient cultures and societies.
