What happens to air pressure as altitude increases?

• increases
• decreases
• stays the same

In the atmosphere, temperature usually ​ (a)   as altitude (height) ​ (b)  

• decreases
• increases

True or false: the troposphere is the most dense and most humid layer of the atmosphere, AND it has the highest air pressure?

• True
• False

Where would the air be the least dense on a climber's hike up a mountain? Hint: it will be more difficult to breathe.

• at the bottom of the mountain
• at the top of the mountain
• halfway through the hike
• three quarters of the way through the hike

Where would the air pressure be the greatest on a climber's hike up a mountain?

• at the bottom of the mountain
• at the top of the mountain
• halfway through the hike
• three quarters of the way through the hike
