Radiometric dates calculated from minerals in sedimentary rocks produce ages that .
a. are just as accurate as when the technique is applied to igneous rocks
b. are too young (postdate sedimentary deposition)
c. are too old (predate sedimentary deposition)
d. represent the time the sediments became lithified

c. are too old (predate sedimentary deposition)

Explanation:

Radiometric dates calculated from minerals in sedimentary rocks produce ages that are too old and often predates the sedimentary deposition.

Radiometric dating involves the uses of radioactive elements in rocks to measure the absolute age of rock.

It involves comparing the daughter to parent ratio because the decay started when the minerals formed in a rock in a period of crystallization or metamorphic event.

(bro she is ancient)

j < 14

j is jakes age

since jake is younger it makes his age less than his sisters

(if you meant she is 14)

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
