Habituation occurs in the ; sensory adaptation occurs in the

According to experts, habituation occurs in the body. It is when there is a reduced physical response to a stimulus after one has been exposed to it repeatedly.

Sensory deprivation, on the other hand, occurs in the brain. This is when ones senses no longer have the same response to stimuli that is continuous or unchanging. 

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
