How does the composition of the atmosphere change with altitude?
It decreases, the proportion of gases changes with altitude.
How does climate change affest the atmosphere?
Climate change can lead to more extreme weather patterns and shifts in climate zones
What actions can individuals take to protect the atmosphere?
reduce, reuse, recycle, use less energy, support policies that protect the environment
