It is the pinna. This is the ear’s part that acts as a funnel to concentrate sounds and guide them into the ear. It is this part’s responsibility to collect sound by acting as a funnel of the ear. It is through the pinna that amplifies the sound and directs the sound to the ear canal. The ear of a human is divided into three parts. The pinna is located and part of the outer ear. Hearing does not take place here but rather this is the part where sound is collected and directed into the the internal passage called auditory canal. From this canal, sound travels or passes to the inner part and that is where the sound is processed.
Answer:
The movement of carbon from the atmosphere to the lithosphere (rocks) begins with rain. Atmospheric carbon combines with water to form a weak acid—carbonic acid—that falls to the surface in rain. The acid dissolves rocks—a process called chemical weathering—and releases calcium, magnesium, potassium, or sodium ions.
