Answer:
The apparent change in the frequency of sound due to the relative motion between the source and the observer is called the Doppler effect.
E.g: The apparent frequency of the whistle of a train increases as it. approaches an observer on the platform and decreases when the train passes the observer.Read more on Sarthaks.com what-is-the-doppler-effect-give-an-example
Description
Definition: Doppler Effect refers to the change in wave frequency during the relative motion between a wave source and its observer. It was discovered by Christian Johann Doppler who described it as the process of increase or decrease of starlight that depends on the relative movement of the star.
Description: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down. The drop in pitch of ambulance sirens as they pass by and the shift in red light are common examples of the Doppler Effect.
Edwin Hubble made the discovery that the universe expands as a consequence of the Doppler Effect. It has important applications in the fields of astronomy and space technology.
The answer is; warming of ocean water in the east of the Pacific Ocean close to the western coasts of South America.
The warming of the oceanic waters causes a current that pushes the warm waters eastwards of the Pacific Ocean at the equator. This counters and overpowers the prevailing trade winds that blow westwards. The currents bring in storms on the West coast of South America as the currents exchange heat with the atmosphere .
The Respiratory zone includes the alveoli, while the conducting zone includes the trachea.

What is the function of the trachea?</h3>
Your windpipe, or trachea, is a component of your airway system. Your lungs get oxygen-rich air through channels called airways. Additionally, they transport carbon dioxide, a waste gas, from your lungs. Air enters your body through your nose, passes through your larynx, and then descends through your windpipe. Or, to put it another way, the trachea is a little tube that joins the larynx to the lungs' bronchi. It's also referred to as a "windpipe." The windpipe is packed with mucus to trap microorganisms since it is vulnerable to many illnesses when air is inhaled through this pipe.
