Anderson's theory of faulting, devised by Ernest Masson Anderson in 1905, is a way of classifying geological faults by use of principal stress. [1] [2] A fault is a fracture in the surface of the Earth that occurs when rocks break under extreme stress. [3] Movement of rock along the fracture occurs in faults.
A detachment fault is a gently dipping normal fault associated with large-scale extensional tectonics. [1] Detachment faults often have very large displacements (tens of km) and juxtapose unmetamorphosed hanging walls against medium to high-grade metamorphic footwalls that are called metamorphic core complexes .
Since teeth eruption follows a pattern, with the eruption of deciduous teeth occurring after birth to the end of infancy at the age of two, and permanent teeth erupting between the ages of five and fourteen, [7] observing which teeth are erupted and developing in a mandible, or whether a tooth is deciduous or permanent in isolated remains, can ...

The vast majority of toothpastes commercially available have RDA values of 250 or less and are unlikely to have a significant impact on abrasion of tooth structure over a lifetime of use. [12] [26] On average, data suggests less than 400 μm of tooth wear occurs over a lifetime using toothpastes of RDA 250 or less. [23]
The uppercase letters A through T are used for primary teeth and the numbers 1 – 32 are used for permanent teeth. The tooth designated "1" is the maxillary right third molar ("wisdom tooth") and the count continues along the upper teeth to the left side. Then the count begins at the mandibular left third molar, designated number 17, and ...
There’s one type of fan reaction that The Bachelor’s Kelsey Anderson has let get under her skin. “I don’t get offended when people are telling me that my teeth are yellow.
