Answer:
Changes in the pressure create the flow of the air to move up and down in the ear and thus create popping sound.
Explanation:
- The ear-popping is caused by the phenomenon of the opening of the Eustachian tube when one swallows and it might be automatically when you blow our nose or are setting in an airplane and this sound is created when the air enters the middle ear through the tube.
Tropical. In this hot and humid zone, the average temperatures are greater than 64°F (18°C) year-round and there is more than 59 inches of precipitation each year.
Dry. These climate zones are so dry because moisture is rapidly evaporated from the air and there is very little precipitation.
Temperate. In this zone, there are typically warm and humid summers with thunderstorms and mild winters.
Continental. These regions have warm to cool summers and very cold winters. In the winter, this zone can experience snowstorms, strong winds, and very cold temperatures—sometimes falling below -22°F (-30°C)!
Polar. In the polar climate zones, it’s extremely cold. Even in summer, the temperatures here never go higher than 50°F (10°C)!
