Particle Physics & Energy
This is the scientific definition of temperature.
Answer: What is the average speed (kinetic energy) of molecules?
This is the measure of the amount of water vapor in the air.
What is humidity?
True or False: Hailstorms usually happen when the ground temperature is below freezing.
What is False?
This is a large parcel of air (hundreds of miles wide) with similar temperature and humidity.
What is an air mass?
This term describes the long-term average (30+ years) of weather conditions.
What is climate?
This method of heat transfer occurs when the ground directly touches air molecules.
What is conduction?
This process occurs when water molecules slow down and clump together to change from gas to liquid.
What is condensation?
This specific characteristic explains why hailstones are hard and often have layers.
What is solid ice?
This is the boundary where two different air masses meet.
What is a front?
This is the primary energy source that drives Earth's weather and water cycle.
What is Sunlight (Solar Radiation)? (I will accept Sun as well)
This type of surface absorbs more sunlight energy, leading to higher temperatures.
What are dark-colored surfaces (like asphalt)?
These tiny solid particles (like dust or smoke) are necessary for water vapor to stick to.
What are Cloud Condensation Nuclei (CCN)?
To grow a larger hailstone, a storm needs a faster one of these.
What is an updraft?
This letter on a weather map represents an area of rising air and potential storms.
What is "L" (Low Pressure)?
These are Mr. Leggio's sons names.
Luca and Max (you will meet Luca if you are in school next Thursday)
When a parcel of air is heated, it becomes less dense and does this.
What is rise?
This is the primary reason we can actually see clouds in the sky.
What is the reflection and scattering of light by liquid droplets or ice crystals?
This is the state of "Relative Humidity" when the air is holding the maximum amount of water vapor possible.
What is 100%?
Across the United States, air masses and storms usually move in this direction.
What is West to East?
This circular motion of fluid is caused by differences in temperature and density.
What is convection?
In the lower atmosphere, this happens to temperature as altitude increases.
What is it decreases?
When an object is suspended at a constant height in a cloud, these two forces are perfectly balanced.
What are gravity and the upward lift force (updraft)?
To produce a "Big Storm," you need high humidity and a large difference in this between the ground and the sky.
What is temperature?
This happens to warm air when a dense cold front moves toward it.
What is it gets pushed upward rapidly?
Ocean currents affect coastal climates by redistributing these two things.
What are heat and humidity? (200 if you only get one)
