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

Ability to Breathe (WHY?)
Temperature (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

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%

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?)

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

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

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
