At which altitude is the troposphere primarily found?

0 - 30,000 ft
15,000 - 50,000 ft
35,000 - 264,000 ft
Above 30,000 ft

The correct answer is: 0 - 30,000 ft

The troposphere is the lowest layer of Earth's atmosphere and is where most weather phenomena occur. It extends from the Earth's surface up to an average altitude of about 30,000 feet (9,000 meters) at the poles and can reach as high as 50,000 feet (15,000 meters) at the equator, but for the sake of this question, the general accepted range is indeed from 0 to approximately 30,000 feet. This layer contains the majority of the atmosphere's mass, and it's characterized by a decrease in temperature with altitude. Understanding the boundaries and characteristics of the troposphere is crucial for aviation and meteorology as it significantly influences flight operations and weather forecasting.
