• Clouds
• Wind
• Air

What are the two most abundant gases in the atmosphere and what are their percentages? 

• Nitrogen 78%, Oxygen 21%
• Water vapor, air mass
• wind, clouds
• fronts, air mass

Why does air have pressure?

• Because air has no mass
• Because air has vapor
• because of clouds

What happens to air pressure as altitude decreases?

• air pressure decreases
• air pressure stays the same
• air pressure increases
• Air pressure does not change.

What happens to the oxygen in the air as altitude increases? 

• the oxygen per cubic meter decreases
• the oxygen per cubic meter increases
• the oxygen per cubic meter stays the same
• the oxygen per cubic meter does not change
