Compare and contrast the troposphere and the stratosphere. How are they different? How are they similar?

Imagine you are a water molecule. Describe your journey through the troposphere. What might happen to you there?

Why is the ozone layer so important? What would happen if it disappeared? Which layer of the atmosphere is it located in?

If a meteoroid enters Earth's atmosphere, it often burns up in the mesosphere. Why does this happen? What does this tell you about the mesosphere?

How does understanding the different layers of the atmosphere help us better understand weather patterns on Earth? Give specific examples.
