Observe the given passage and answer the questions given below:
Two groups of students recorded weather conditions at different places on the same day.
Location A was a coastal city near sea level. The weather was warm and humid, with clouds forming in the afternoon.
Location B was a mountain station located at a much higher altitude. The students observed that the air was cooler and the sky remained clear for most of the day.
During a discussion, a meteorologist explained that the atmosphere is divided into different layers. Most weather phenomena occur in the troposphere, which is heated from the Earth's surface. As altitude increases, temperature generally decreases in this layer. The meteorologist also explained that the atmosphere is held around the Earth by gravity and that atmospheric layers help regulate weather and climate.
