tropopause
-
stratosphere
-
troposphere

-
the majority of the weather is contained in the troposphere and its upper boundary is the tropopause
-
the majority of the weather is contained in the tropopause and its upper boundary is the troposphere
-
the majority of the weather is contained in the troposphere and its upper boundary is the stratosphere
Pregunta 9
Pregunta
