atmospheric

• What is the Earth's atmosphere primarily made of?

  Nitrogen
• Why is oxygen important in the Earth's atmosphere?

  It allows us to breathe
• What role do greenhouse gases play in the atmosphere?

  They keep the planet warm
• What is the function of the ozone layer?

  It blocks harmful radiation
• Where is the density of gas particles highest in the atmosphere?

  Near the Earth's surface
• How does atmospheric pressure change with elevation?

  It decreases as elevation increases
• What happens to air particles as you go higher in the atmosphere?

  There are fewer air particles
• What is the relationship between air particle collisions and pressure?

  More collisions result in higher pressure
• If an object is at sea level, how does it compare to one at 1,000 meters in terms of air particles?

  It has more air particles around it
• What does a higher force indicate in terms of pressure?

  It creates a higher pressure
• What contributes to the pressure experienced by an object at sea level?

  The weight of gas particles above it
• Why do mountain climbers need oxygen cylinders?

  The air is too thin to breathe
• What are the main factors affecting atmospheric pressure?

  • Density of gas particles
  • Weight of gas particles above
• How does atmospheric pressure change with altitude?

  • Decreases with increasing elevation
  • Fewer air particles at higher altitudes
• What is the significance of gas particle collisions in atmospheric pressure?

  • More collisions lead to higher pressure
  • Pressure is influenced by the density of particles
