To use an adultâs social security number to open a line of credit, a thief would have to provide personally identifiable information, which would have to match entries that the adult has already established.
Water density is governed by temperature and salinity; consequently, the thermocline coincides generally with the pycnocline, or layer in which density increases rapidly with depth. The middle layer of water in a lake or reservoir during the summer is also called a thermocline.
Most people will never see the deep waters of the ocean...they are just too deep! The pycnocline (meaning rapid change of density) separates the surface layer of the ocean from the deep ocean. Deep ocean water has a temperature of about 3 degrees Celsius and a salinity measuring about 34-35 psu.
