Cloud Formation
How does cloud formation begin?
The sun heats the earth’s surface (ground, plants, bodies of water, etc.) through a form of heat transfer called radiation
As the temperature increases, the movement of the particles...
Increases
What is radiation?
The transfer of heat through electromagnetic waves.
Where can you find the weekly agenda?
Wits & Google Classroom?
In which season are hailstorms not as prevalent?
Winter.
What happens to liquid water on the Earth's surface (within the ground, bodies of water, etc.), as the sun heats it up?
The liquid water transitions to the gas form (water vapor) through a process called evaporation.
As the movement of the particles decreases, the temperature of the particles...
Decreases
What is evaporation?
When individual molecules on the surface of a liquid gain enough kinetic energy (energy of motion energy), they convert from a liquid to a gas.
If you turn an assignment in late, what is deducted from your original score?
10% off.
In what part of the United States are severe hailstorms most prevalent?
Central US.
How do the air particles and water vapor molecules near the surface begin to rise?
The ground particles give energy (heat) to the air particles they come in contact with (near the surface) through the process called conduction. Once those particles/molecules are warmed, they become less dense and rise.
As the temperature decreases, the particles become ________ dense. Why?
As the temperature decreases, the particles move slower and come closer together. This, causes the particles to be more dense.
What is deposition?
Deposition is the process where a substance changes directly from a gas to a solid, completely bypassing the liquid phase.
If you left early for a doctors appointment on Tuesday, what day are you expected to turn the work in (without it being late)?
Thursday.
In what part of the United States are hailstorms less prevalent?
Western US.
Once the water vapor molecules rise up to higher altitudes and get colder, what must they do before they can condense or deposit?
They must latch onto a cloud condensation nuclei (CCN) before that process can begin.
What happens to a pocket of particles if they are the same density as the air around them?
They will stay at that altitude.
What is relative humidity?
The amount of water vapor within the air vs the maximum amount it can hold.
What day is your quiz?
Tuesday, November 4th.
What time during the day do hailstorms most likely occur? (Morning, Afternoon, Late Afternoon, Evening)
The tiny water droplets and ice crystals that make up a cloud are relatively large compared to the water vapor in the air. When white sunlight hits these larger droplets, it is scattered (or redirected) equally in all directions.
As temperature decreases, the air holds ________ (more or less) water vapor. Why?
What is density?
The relationship between mass (the amount of matter in a sample) and volume (the amount of space it takes up).
When you are absent, what two things are you expected to look at (at home) to catch-up on missing classwork/assignments.
Weekly Agenda & Unit 1- Slides
Why do hailstorms occur more in hotter temperatures?
The rapid, vertical rise of warm air creates immensely powerful currents known as updrafts.
