Quiz on Changes in the Atmosphere with Altitude

What happens to air pressure as altitude increases?

• Air pressure fluctuates

• Air pressure increases

• Air pressure remains constant

• Air pressure decreases

How does air density change with altitude?

• It fluctuates randomly

• It remains the same

• It decreases with altitude

• It increases with altitude

What is the effect of altitude on the space between air molecules?

• Less space at higher altitudes

• More space at higher altitudes

• No change in space

• Space is irrelevant to altitude

How does oxygen availability change at high altitudes compared to sea level?

• Oxygen levels are the same

• Less oxygen at high altitudes

• More oxygen at high altitudes

• Oxygen is not affected by altitude

What happens to temperature as you move from the Earth's surface to the top of the atmosphere?

• Temperature varies in complex ways

• Temperature remains constant

• Temperature always decreases

• Temperature always increases
