Lesson 4: Wind Flashcards
(13 cards)
1
Q
Wind
A
- The movement of wind from areas of high pressure to low pressure
- Global scale convection current
2
Q
How is temperature effected by global wind patterns?
A
- Wind causes the transfer of thermal energy from warmer to cooler areas until equilibrium is reached
3
Q
Coriolis Effect
A
- The deflection or curving of moving objects (like air or water) due to Earths rotation
4
Q
Jet Streams
A
- Fast moving, narrow bends or air that blow up high in the atmosphere (troposphere)
- Flow from west to east around Earth
5
Q
Specific Heat Capacity
A
- The amount of heat needed to raise the temperature of of a substance by 1 degree Celsius
6
Q
What does it mean to have a high specific heat capacity?
A
- It takes a lot of energy to change the energy of a substance
Ex. water
7
Q
Is energy absorbed or released in endothermic reactions?
A
- Absorbed
8
Q
What state changes are endothermic (energy absorbing)?
A
- Melting (solid to liquid)
- Evaporation (liquid to gas)
- sublimation (solid to gas)
9
Q
Is energy absorbed or released in exothermic reactions?
A
- Released
10
Q
What state changes are exothermic (energy releasing)?
A
- Freezing (liquid to solid)
- Condensation (gas to liquid)
- Deposition (gas to solid)
11
Q
Which transformation breaks bonds? Which transformation creates them?
A
Endothermic: breaks bonds
Exothermic: creates bonds
