Radiocarbon dating can only be used to determine the age of objects that were once alive, such as fossilized bones or plants. It is of no use in dating geological formations that do not contain some remains of formerly living substances.
Carbon atoms are contained in most cells of all living things on Earth. Most carbon atoms (98.89 percent) are called carbon-12 because they have 6 neutrons and 6 protons in their nuclei. Most of the remaining atoms (1.11 percent) have 7 neutrons along with their 6 protons and are called carbon-13 atoms, but a very small quantity (called a trace amount) of carbon atoms have 8 neutrons and 6 protons. These and are called carbon-14 atoms.
Carbon-14 atoms are radioactive and are referred to as radiocarbon. They are unstable, and decay slowly by releasing electrons before evolving into nitrogen-14 atoms. A living organisms constantly absorbs carbon in its body systems by respiration and processing nutrients, and the amount of carbon-14 it contains remains fairly constant for as long as it lives. The carbon-14 decays without being replaced after the organism dies and half of the carbon-14 nuclei will disintegrate in about 5,730 years. The amount of carbon-14 that has disintegrated in a fossilized organism can be calculated and used for determining its age.
Radiocarbon dating is limited to dating materials up to around 50,000 years old because of the short half-life of the carbon-14 isotope. This makes it less useful for geological timescales, which often span millions or billions of years. For older materials, other dating methods like uranium-lead dating are more appropriate due to their longer half-lives.

Why is Precambrian history more difficult to study than more recent geological history?
Precambrian history is more difficult to study because the rocks from this era have undergone significant alteration and destruction over billions of years, making them harder to interpret. Also, the lack of well-preserved fossils in Precambrian rocks makes it challenging to reconstruct ancient environments and ecosystems accurately. Additionally, the vast timescale of the Precambrian era poses difficulties in accurately dating events and establishing a precise chronology of geological events.
Can bedrock be broken?
Bedrock is the hardest part of Earth's crust and is generally considered unbreakable by human tools and equipment. In practice, it is rarely broken through, except by natural geological processes over long periods of time.
What is a dry barren place where rain rarely falls?
A desert is a dry, barren place where rain rarely falls and vegetation is limited. These areas typically have extreme temperatures and low humidity levels.
Do tornadoes cause weathering erosion and deposition?
Tornadoes do not directly cause weathering, erosion, or deposition. However, tornadoes can indirectly contribute to these processes by moving and depositing sediment and debris. The strong winds and flying debris associated with tornadoes can impact geological features and accelerate the process of erosion in affected areas.
Is basalt older than sandstone?
Basalt is typically an igneous rock formed from the solidification of magma, making it generally older than sandstone, which is a sedimentary rock formed from the accumulation of sediments. However, the relative ages of rocks can vary depending on the specific geological context.
What is the age of fossils that can be measured by what dating?
Fossils themselves can very rarely be dated by any means...their age is usually judged by the geological assessment of the area and layer in which they are found
What is another way of saying are not always used?

Why is carbon dating not useful for dating metal artifact?
Metal artifacts rarely contain residues of organic products. Carbon-14 dating is adequate only for artifacts containing organic materials.
What is it when your dating and you rarely see each other and you meet a different guy and you hook up with them?
Slutty
Name something people try their luck with but rarely win?
lottery ticket, casino games, dating
What is rarely found on earth because earths surface is constantly changing?
Stable geological formations, such as mountains, are rarely found on Earth because the surface is constantly shifting due to processes like tectonic plate movement, erosion, and volcanic activity. This dynamic nature of the Earth's surface means that stable geological formations are uncommon and constantly evolving.
How do you spell houda?
The word sought may be houdah, also howdah, a seat atop an elephant (more rarely applied to camels).
What radioactive element is not commonly used in dating archaeological artefacts?
The most often used radioactive elements used in radiometric dating are carbon, potassium-argon and uranium-lead.Other elements are not, or very rarely used.
What is the definition of monastery?
A house of religious retirement, or of secusion from ordinary temporal concerns, especially for monks; -- more rarely applied to such a house for females.
Is it illegal to date a 16 year old girl?
Dating itself is very rarely illegal in most countries and states. What might be illegal is sex.
What is the words for hermaphrodites?
Slang terms- Morph, morphadite, he-she A.C./D.C. ( a possible nod to Electra!) Half and half. oddly 50/50, which is applied to racial mixes and also ships that are mixed sail and power, it is rarely applied to Hermaphrodites.
Is humpback one word?
The term "humpback" applied to whales or other animals is one word. The corresponding human term (rarely used today) is "hunchback."
