Question

according to the passage, age of rocks crq: . how does the age of oceanic crust change with distance from mid - ocean ridges? (3pts); . what technique was described to determine the age of crustal rocks? (3pts); . where is new oceanic crust formed? (3pts) . be sure to answer in complete sentences using proper grammar and use punctuation. (1pt)

Explanation:

1. The age of oceanic crust increases with increasing distance from mid - ocean ridges as new crust is formed at the ridges and moves outward over time.
2. Radiometric dating is a common technique used to determine the age of crustal rocks. It measures the decay of radioactive isotopes in the rocks.
3. New oceanic crust is formed at mid - ocean ridges where tectonic plates are diverging and magma rises to the surface to create new crust.

Answer:

1. The age of the oceanic crust increases as the distance from mid - ocean ridges increases.
2. Radiometric dating is the technique used to determine the age of crustal rocks.
3. New oceanic crust is formed at mid - ocean ridges.
