Archaeology

No, radiocarbon dating is used to determine the age of organic materials up to around 50,000 years old. To determine the age of Earth, scientists use other methods like uranium-lead dating of rocks or meteorites, which provide an estimate of about 4.5 billion years.

In most cases radiocarbon dating is the most commonly used method for dating an artifact made from a material which was once part of a living organism. However, there are other methods available. Although radiometric dating is a useful tool dendrochronology (also known as tree ring dating) remains the most effective and accurate method of dating certain species of wood (where a suitable sample can be found).

There are probably thousands. Most archaeologists specialize in one geographic area or one time period, often both! An archaeologist may also specialize in a particular aspect such as flora or fauna, architecture, ceramics or lithics. There is no end to the possibilities. Some of them are listed below including some theoretical approaches.

Start by phoning the Archaeology Department of your nearest University, or speak to one of the curators at the nearest museum. An official list of all labs which offer radiocarbon dating can be found in the related links below (current 2009).

Silicon is the second most abundant element in the Earth's crust, making up about 28% of its mass. It is commonly found in the form of silicon dioxide (silica) in rocks, sand, and soil. It is also found in many minerals, such as quartz and feldspar.

As archaeology is such a broad subject which borrows a lot of its theory and methodology from other subjects a lot of subjects would be relevant. Most common combinations would probably include history, social or physical anthropology, geosciences, physics or biology. However, choose based on what interests you.

Doppler effect. This effect causes the wavelengths of light from a star to appear shorter (blueshifted) as it moves towards the Earth and longer (redshifted) as it moves away, providing valuable information about the star's motion in space.

Sylvia Earle is a renowned marine biologist who has made significant contributions to marine science and conservation. She is known for her research on marine ecosystems, deep-sea exploration, and efforts to protect the ocean environment. Earle has also been involved in the discovery of new species and the promotion of marine conservation initiatives around the world.

Archaeological excavations at Jenne-jeno revealed evidence of a sophisticated urban center in ancient West Africa. Findings included evidence of iron smelting, pottery production, agriculture, and a complex social structure with evidence of trade networks. This suggests that Jenne-jeno was a thriving hub of economic, cultural, and technological activity in the region.

Archaeological refers to the study and investigation of past human societies through the analysis of artifacts, structures, and other material remains. It involves interpreting material culture to understand ancient societies and their practices.

A sundog around the moon, also known as a lunar halo, is formed when light is refracted and reflected in ice crystals in the atmosphere. The ice crystals act like tiny prisms, bending the light and creating a ring of light around the moon. Sundogs are most commonly seen when the sky is filled with high, thin clouds made of ice crystals.

Because the metal magnesium was first produced in 1808 in England by Sir Humphry Davy.

A peat bog is a type of wetland characterized by the accumulation of peat, which is made up of decayed organic matter like dead plants. Peat bogs are important for storing carbon, regulating water flow, and providing habitat for unique plant and animal species. They are found in cool, damp climates around the world.

By examining teeth, growth plates in bones, and the development of bones, archaeologists can estimate a person's age at the time of death. Additionally, analysis of burial practices, grave goods, and other artifacts can provide clues to the age of the individual.

The Mississippians were a mound-building Native American culture that declined around 1450 due to a combination of environmental factors, social disruptions, and possibly conflict with other groups. This decline led to the dispersal of Mississippians into other cultures and the abandonment of their large ceremonial centers.

The process of mummification in ancient Egypt typically took around 70 days to complete. This involved removing internal organs, dehydrating the body with salts, and wrapping it in linen bandages. The length of the process could vary depending on the deceased's social status and resources available.

they were lucky. I read an article in one of my journals. What I am going to do for this answer is; superstock.com/stockphotography/cave/printings. I will be back to this one because I was interested that the Saharan climate used to be much different.

Cave painting artists used a form of perspective by depicting things closer to them larger in size, while things farther away were smaller. This technique gave the illusion of depth and distance in their paintings.

Excavation season refers to the period in the year when archaeologists undertake fieldwork (normally excavation) and is most often in the summer months. There is no seasonal division in commercial archaeology, where excavation takes place year round.

Archaeologists are responsible for conducting research, excavations, and surveys following ethical standards and laws. They also have a responsibility to document and preserve cultural heritage for future generations and to engage with local communities and stakeholders in their work.

A diagnostic artifact is an incidental finding on a diagnostic test, like an MRI or X-ray, that is not related to the primary reason for the test. It is important for radiologists and healthcare providers to differentiate between clinically significant findings and these artifacts to avoid misinterpretation. Diagnostic artifacts can be caused by various factors, including patient movement, equipment malfunction, or image processing errors.

The moa, flightless birds native to New Zealand, lived on Earth until about 600 years ago. They were hunted to extinction by the Maori people and possibly also by introduced predators like humans and dogs.
