C
Stratosphere
D
Thermosphere
Verified step by step guidance1
Understand the structure of Earth's atmosphere, which is divided into several layers: Troposphere, Stratosphere, Mesosphere, and Thermosphere, each with distinct characteristics.
Recall that the Troposphere is the lowest layer of the atmosphere, extending from Earth's surface up to about 8-15 kilometers, where most weather phenomena occur.
Recognize that hot-air balloons rely on buoyancy and are affected by weather conditions, so they operate within the layer where weather happens, which is the Troposphere.
Note that the Stratosphere, Mesosphere, and Thermosphere are higher layers with different temperature profiles and are not suitable for typical hot-air balloon travel.
Conclude that a typical hot-air balloon travels in the Troposphere, the atmospheric layer closest to Earth's surface.
