What combination of conditions is most likely to lead to hail formation?

• Warm air at high altitudes and cold air near the ground
• Cold air at high altitudes and warm air near the ground
• Uniform temperature throughout the atmosphere
• Low humidity and strong downdrafts

How does relative humidity change as temperature increases, assuming the amount of water vapor in the air remains constant?

• It increases
• It decreases
• It stays the same
• It fluctuates randomly

What is the primary difference between wind and gusts?

• Wind is always stronger than gusts
• Gusts are sudden, short bursts of wind
• Wind only occurs during storms
• Gusts only occur at night

Which statement best describes the relationship between density and air temperature?

• Warm air is more dense than cold air
• Cold air is less dense than warm air
• Warm air is less dense than cold air
• Temperature has no effect on air density

What does temperature measure in the context of weather?

• The color of the sky
• The average kinetic energy of air particles
• The amount of rainfall
• The speed of wind

Which of the following is NOT a requirement for cloud formation?

• Water vapor
• Cooling of air
• Condensation nuclei
• Strong winds

What is the primary method by which the Sun heats the Earth's surface?

• Conduction
• Convection
• Radiation
• Precipitation

Where does conduction primarily occur in the atmosphere?

• Between clouds
• Between the ground and the air directly touching it
• In the upper atmosphere
• Within raindrops

How do particles in a gas behave compared to those in a solid?

• Gas particles are closer together and move slower
• Gas particles are far apart and move quickly
• Gas and solid particles behave the same way
• Gas particles are tightly packed and vibrate in place

What happens to air particles as temperature increases?

• They move slower and come closer together
• They move faster and spread apart
• They stop moving entirely
• Their behavior is unaffected by temperature
