How old it is compared to another specimen in relation.
The temperature and salinity affect deep water current since
The water density depends on temperature and salinity . The deep currents from where the density of ocean water increases. The decrease of the temperature of water led to increase in water salinity while the density of water also increases.
Replication is when you copy something, and repetition is when you keep doing it over and over again. i hope this helps :-D
