Amount of certain radioactive isotope in an object is compared with a reference amount. this ratio can then be used amount.
Radiometric dating is based on the principle that certain isotopes decay at a constant rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how much time has passed since the rock formed. This method provides an accurate estimate of the absolute age of the rock or fossil.
Radiocarbon dating seeks to age fossils based on half lives of radioactive elements, while thermoluminescence is a form of luminescence that occurs when previously absorbed energy from is remitted as light upon heating of the material.
Yes, the Philippines is an archipelago because it is composed of about 7,641 islands. An archipelago is a group of islands clustered together, which is why the Philippines fits this definition.
Someone who studies history is called a historian. Historians research, analyze, and interpret historical events, people, and societies to understand and explain the past.
A person who studies events and the past is called a historian. Historians analyze and interpret historical evidence to understand and explain past events, societies, and cultures.
Radiometric dating is based on the principle that certain isotopes decay at a constant rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how much time has passed since the rock formed. This method provides an accurate estimate of the absolute age of the rock or fossil.
To fully explain radioactive decay you need quantum mechanics.
To be accurate, a theory must continue to explain what
To be accurate, a theory must continue to explain what
Scientists determine the age of Earth using radiometric dating methods on rocks and minerals. By measuring the decay of radioactive elements in these materials, they can estimate the age of the planet to be about 4.5 billion years old.

In contrast, for an ellipse it is the ''sum'' of these distances that is a constant
relative and absolute. relative is determining the relative order of past events, without necessarily determining their absolute age. Absolute is the process of determining an approximate computed age in archaeology and geology.
Radioactivity is used to date rocks through a process called radiometric dating, which relies on the decay of radioactive isotopes in the rock to determine its age. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how long it has been decaying and thus determine its age. This method is commonly used in geology to determine the age of rocks and minerals.
You need to explain what transformation you refer to. The transformation of the empire in the west relation to what? You also need to explain why it would need to be accurate/inaccurate.
