Herbchronology Dating methods in archaeology[ edit ] Same as geologists or paleontologists , archaeologists are also brought to determine the age of ancient materials, but in their case, the areas of their studies are restricted to the history of both ancient and recent humans. Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity. It is commonly assumed that if the remains or elements to be dated are older than the human species, the disciplines which study them are sciences such geology or paleontology, among some others. Nevertheless, the range of time within archaeological dating can be enormous compared to the average lifespan of a singular human being. As an example Pinnacle Point ‘s caves, in the southern coast of South Africa , provided evidence that marine resources shellfish have been regularly exploited by humans as of , years ago. It was the case of an 18th-century sloop whose excavation was led in South Carolina United States in Dating material drawn from the archaeological record can be made by a direct study of an artifact , or may be deduced by association with materials found in the context the item is drawn from or inferred by its point of discovery in the sequence relative to datable contexts.

Abiogenesis and Evolutionary history of life Phylogenetic tree of life on Earth based on rRNA analysis Chemical reactions led to the first self-replicating molecules about four billion years ago. A half billion years later, the last common ancestor of all life arose. The resultant molecular oxygen O2 accumulated in the atmosphere and due to interaction with ultraviolet solar radiation, formed a protective ozone layer O3 in the upper atmosphere.
Aided by the absorption of harmful ultraviolet radiation by the ozone layer, life colonized Earth’s surface.

I am an Earthling and an Avenger. But today I stand as one with the settlers of Torfa, who claim this planet and its resources as they were freely given in the aftermath of the Behemoth disaster They are a peaceful people, but I am a woman of war. If you move against them, you move against me. I am willing to die here today, for this cause. I have made my choice

She overheard them say that they were looking for “Kal-El” and kept under wraps to avoid being hurt. After Lex found her close to the site, he took her back to the Luthor Mansion to recover. Lana went to the Smallville Medical Center, where the kryptonians were laying siege and about to kill Lois Lane, and told them she knew where Kal-El was.
She led them to the Luthor Mansion where they were exposed to the meteor rock in the secret vault, but they were able to escape. Before the aliens could kill Lana, Clark arrived and send them into the Phantom Zone. Lex helped Lana cover up Genevieve Teague’s death, falsifying evidence that she died as a result of the meteor shower and Lana was relieved to learn this.
After Clark saved Lana, he decided that he and Lana could have a real and honest relationship and finally start dating. During this time, Lana finally felt that Clark was totally open with her and the two had sex together for the first time. However, their happiness did not last long due to the constant threats that Clark had to face and things between the two began to change again.
As Lana became obsessed with what happened during the last meteor shower, she started studying astronomy and meteors to try to discover the truth and came to the conclusion that there was possibly aliens living among them, much to the dismay of Clark.

Radioactive decay[ change change source ] All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus. Elements exist in different isotopes , with each isotope of an element differing in the number of neutrons in the nucleus. A particular isotope of a particular element is called a nuclide.
Some nuclides are naturally unstable. That is, at some point in time, an atom of such a nuclide will spontaneously change into a different nuclide by radioactive decay. The decay may happen by emission of particles usually electrons beta decay , positrons or alpha particles or by spontaneous nuclear fission , and electron capture.
The age is calculated from the slope of the isochron line and the original composition from the intercept of the isochron with the y-axis. The mathematical expression that relates radioactive decay to geologic time is: This is well known for most isotopic systems. It shows the age of the sample, and the original composition. Preconditions[ change change source ] The method works best if neither the parent nuclide nor the daughter product enters or leaves the material after its formation.

The ratio of carbon to carbon at the moment of death is the same as every other living thing, but the carbon decays and is not replaced. The carbon decays with its half-life of 5, years, while the amount of carbon remains constant in the sample. By looking at the ratio of carbon to carbon in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing fairly precisely.
A formula to calculate how old a sample is by carbon dating is:
Carbon Dating is a BrainPOP episode launched on August 7, Appearances Tim, Moby, Ewan.

Under the effects of a “yellow” sun, Superboy possesses the same potential powers as an average Kryptonian. Under optimal conditions, this is the main source of Superboy’s super powers as they are contingent upon exposure to solar radiation from a yellow sun star system. His biological make up includes a number of organs which lack analogues in humans and whose functions are unknown. It is believed that between one or more of these and his bio-cellular matrix, “yellow” solar energy is stored for later use.
This allows for the use of these powers to fade when yellow solar radiation is not available instead of immediate failure. Superboy can, as a conscious act, fire beams of intense heat at a target by looking at it. He can vary the heat and area affected.
