Answer:
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.
- Sedimentary rocks are often made up of re-worked minerals.
- They are derived from pre-existing igneous and metamorphic rocks.
- When radioactive minerals from these sources finds their way into sediments, they give the age of their parent rock and not that of the sedimentary rock because their activity is not being reset.
Answer:
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. ... This changing of rock types is called the "Rock Cycle".

Uneven; poor by u.s standards
When a product is elastic, a change in price quickly results in a change in the quantity demanded. When a good is inelastic, there is little change in the quantity of demand even with the change of the good's price. ... If the market price goes up, firms are likely to increase the number of goods they are willing to sell.
