Comparing and Contrasting Air

Sea Level vs.

The Top of a Mountain

Sea-Level Top of a Mountain

AltitudeDensity (WHY?)

Percentage of Nitrogen and Oxygen

Ability to Breathe (WHY?)

Temperature (WHY?)

Air Pressure (WHY?)

Sea-Level Top of a Mountain

Altitude LowerDensity (WHY?)

Percentage of Nitrogen and Oxygen

Ability to Breathe (WHY?)

Temperature (WHY?)

Air Pressure (WHY?)

Sea-Level Top of a Mountain

Altitude Lower HigherDensity (WHY?)

Percentage of Nitrogen and Oxygen

Ability to Breathe (WHY?)

Temperature (WHY?)

Air Pressure (WHY?)

Sea-Level Top of a Mountain

Altitude Lower HigherDensity (WHY?) More dense (more molecules per

given space) because gravity is pulling the molecules to the lowest point

Percentage of Nitrogen and Oxygen

Ability to Breathe (WHY?)

Temperature (WHY?)

Air Pressure (WHY?)

Sea-Level Top of a Mountain

Altitude Lower HigherDensity (WHY?) More dense (more molecules per

given space) because gravity is pulling the molecules to the lowest point

Less dense (fewer molecules per given space) because gravity is pulling the molecules to the lower point

Percentage of Nitrogen and Oxygen

Ability to Breathe (WHY?)

Temperature (WHY?)

Air Pressure (WHY?)

Sea-Level Top of a Mountain

Altitude Lower HigherDensity (WHY?) More dense (more molecules per

given space) because gravity is pulling the molecules to the lowest point

Less dense (fewer molecules per given space) because gravity is pulling the molecules to the lower point

Percentage of Nitrogen and Oxygen

Nitrogen- 78%Oxygen- 21%

Ability to Breathe (WHY?)

Temperature (WHY?)

Air Pressure (WHY?)

Sea-Level Top of a Mountain

Altitude Lower HigherDensity (WHY?) More dense (more molecules per

given space) because gravity is pulling the molecules to the lowest point

Less dense (fewer molecules per given space) because gravity is pulling the molecules to the lower point

Percentage of Nitrogen and Oxygen

Nitrogen- 78%Oxygen- 21%

Nitrogen- 78%Oxygen- 21%

Sea-Level Top of a Mountain

Altitude Lower HigherDensity (WHY?) More dense (more molecules per

Percentage of Nitrogen and Oxygen

Nitrogen- 78%Oxygen- 21%

Nitrogen- 78%Oxygen- 21%

Ability to Breathe (WHY?)

Easier- There are more molecules at sea-level, so you breathe in more oxygen per breath

Temperature (WHY?)

Air Pressure (WHY?)

Sea-Level Top of a Mountain

Altitude Lower HigherDensity (WHY?) More dense (more molecules per

given space) because gravity is pulling the molecules to the lowest point

Less dense (fewer molecules per given space) because gravity is pulling the molecules to the lower point

Percentage of Nitrogen and Oxygen

Nitrogen- 78%Oxygen- 21%

Nitrogen- 78%Oxygen- 21%

Ability to Breathe (WHY?)

Easier- There are more molecules at sea-level, so you breathe in more oxygen per breath

More difficult- There are fewer molecules on the mountain-top, so you have to breathe in more to get enough oxygen

Temperature (WHY?)

Air Pressure (WHY?)

Sea-Level Top of a Mountain

Altitude Lower HigherDensity (WHY?) More dense (more molecules per

given space) because gravity is pulling the molecules to the lowest point

Less dense (fewer molecules per given space) because gravity is pulling the molecules to the lower point

Percentage of Nitrogen and Oxygen

Nitrogen- 78%Oxygen- 21%

Nitrogen- 78%Oxygen- 21%

Ability to Breathe (WHY?)

Easier- There are more molecules at sea-level, so you breathe in more oxygen per breath

More difficult- There are fewer molecules on the mountain-top, so you have to breathe in more to get enough oxygen

Temperature (WHY?) Warmer- Since the air is more dense, there are more molecules to hold the heat

Air Pressure (WHY?)

Sea-Level Top of a Mountain

Altitude Lower HigherDensity (WHY?) More dense (more molecules per

given space) because gravity is pulling the molecules to the lowest point

Less dense (fewer molecules per given space) because gravity is pulling the molecules to the lower point

More difficult- There are fewer molecules on the mountain-top, so you have to breathe in more to get enough oxygen

Temperature (WHY?) Warmer- Since the air is more dense, there are more molecules to hold the heat

Cooler- Since the air is less dense, there are fewer molecules to hold the heat

Temperature (WHY?) Warmer- Since the air is more dense, there are more molecules to hold the heat

Cooler- Since the air is less dense, there are fewer molecules to hold the heat

Air Pressure (WHY?) Higher- There is a “larger column of air” pushing down, which means there are more molecules pushing down creating more force
