The layer of the atmosphere being described in the passage is the troposphere.

To determine which layer of the atmosphere is being described in the passage, we can look for clues within the text. The passage states that "Many airplanes fly in the layer of the atmosphere where weather occurs." This implies that the mentioned layer of the atmosphere is where weather happens most frequently. The passage also mentions that the air in this layer can feel bumpy and cause turbulence. By considering this information, we can conclude that the layer being described is the troposphere (option d).

To better understand the layers of the atmosphere and their characteristics, you can refer to resources such as textbooks, online articles, or educational websites. These sources will provide detailed explanations with diagrams and further information to expand your knowledge on the topic.
