List the ways the age of seafloor rocks can be determined.

Due to thermal subsidence, the depth will give a rough age for seafloor younger than 70-100

Magnetic anomalies identification of the anomaly allows getting the sea floor age from the magnetic time scale.

i believe the answer would be b. hope it : )

air enters through the nose, moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi andbronchioles till the alveoli.
