In the vertical structure of the atmosphere, which one is the lowest layer?
Stratosphere
Troposphere
Mesosphere
Ionosphere
Most weather activity occurs in which atmospheric layer:
Stratosphere
Troposphere
Mesosphere
Ionosphere

None of the above
The ozone layer lies in the :
Stratosphere
Troposphere
Mesosphere
Ionosphere
