the exosphere, which is the outermost layer the troposphere, which is the lowest layer the thermosphere, which has the highest temperature the stratosphere, which contains a sub-layer of ozone
I gave my students this multiple choice question: In which layer of the atmosphere does most of Earth's weather occur?

Only one answer is correct among these 4 choices:
- the exosphere, which is the outermost layer
- the troposphere, which is the lowest layer
- the thermosphere, which has the highest temperature
- the stratosphere, which contains a sub-layer of ozone

Could you tell me which one is correct?

the troposphere, which is the lowest layer
