Metric System
What do you measure length in in the metric system?
meters (centimeters, millimeters)
What is air made of?
Matter/Atoms and molecules
The sun transfers heat to your skin and burns you. Which type of energy transfer is this?
How fast the wind is blowing is the definition of...
Wind Speed
High pressure means what kind of weather?
Happy weather, clear skies/sunny
What metric unit do we use to measure mass?
grams (kilograms, milligrams)
You close off the end of a syringe and push on the plunger but it won't go all the way down. This proves that air has...
volume (it takes up space)
This type of energy transfer is caused by fluids with different temperatures, and therefore different densities.
Convection
A person who studies the weather...
Meteorologist
Low pressure air means ____________ (warm or cold) air is __________ (rising/sinking).
Warm, rising
What tool do we use to measure mass?
triple beam balance
How can you change the density of air?
Compress or Expand it. OR Add or take away heat.
You pick up your favorite Christmas mug from the microwave and it burns your hand. Which type of energy transfer did this?
Conduction
The amount of matter in a given space or volume is the definition of...
Density
What kind of wind is created by giant convection currents around the earth?
Global Winds
What tool do we use to measure air pressure?
barometer
Warm air is ___________ dense than cold air, so it will go ___________ (up or down).
less, up
In conduction, energy is always transferred from the particle with _________ (less or more) energy to the particle with (less or more) energy.
More to less
What is the formula for density?
D= M/V
What kind of local wind is created by warmer land and cooler water?
Sea Breeze
What unit do we use to measure the volume of a SOLID (like a box)?
cm3 (centimeters cubed)
As you go up in the atmosphere, there are fewer and fewer air particles. That means the pressure as you go up is _________.
dropping, lower
Explain how the three types of energy transfer work together to create convection cells outside.
The sun's radiation heats up the ground, the ground heats up the air by touching it which is conduction, and the air rises and falls because of convection.
A substance where particles are free to flow is the definition of...
Fluid
Why do winds curve on their path rather than go straight to where they are going?
The Coriolis Effect (the spin of the Earth)
