供稿人: Raiten
What gas makes up a majority of Earth'satmosphere?
oxygen O2
argon   Ar 
nitrogen N2
carbon dioxide CO2
at warm temperatures molecules grow in size
at warm temperatures molecules slow down
at warm temperatures molecules move around
more (more kinetic energy)
at warm temperatures molecues stop moviing
How do molecules at warm temperatures differ 
from molecules at cool temperatures?
What might happen if Earth didn't have an atmosphere?
everything would go flying off into space
We wouldn't be able to breathe 
The seasons would be longer
The Earth's rotation would stop
What happens when you put a piece of wood
into a campfire?
chemical energy in the wood is released
electrical energy in the wood is released
energy is released due to friction
solar energy is released
Place the following atmospheric layers in the correct sequence from lowestto highest
A)exosphere   B) stratosphere  C)troposphere
C, A, B
C, B, A
B, C, A
A, B, C
Why is it difficult to breathe at high altitudes? 
because there is more carbon dioxide
the higher you go
because there is no oxygen in the troposphere
because atmospheric gasses become thinner
the higher you go (less molecules of gas)
because you are closer to the sun the 
higher you go
If you wanted to fly through a cloud, which
atmospheric layer would you fly through?
exosphere
stratosphere
mesophere
trophosphere
stay all around the radiator
 spread out evenly throughout the room
stay near the floor
 move all to thesolar collector
In this picture, the home is beingheated by a solarheating system.The heated air that comes from theradiator will.....
The type of heat transfer that occurs when the atoms or  molecules flow is ________________
convection 
radiation
conduction
sun's rays
As molten lava flows into the ocean, it quicklycools and hardens.  Which of the following bestdescribes why this occurs?
 The ocean water is more dense than the lava
Thermal energy in the lava transfers to the
cooler ocean water
 Thermal energy in the ocean water is 
transferred into the lava
 The salt in the ocean water reacts with the 
lava
Which best represents the direction that heat will
move when the test tubes are placed in the water bath?
heat will move from the 20 into the 50 and 10
heat will move from the 10 to the 20 and 50
heat will move from the 50 toward the 20 and 10
A teacher puts one testtube of 50 degree liquidand one test tube of 10 degree liquid into a 20degree water bath as shown.
The compound Ammonia is found in trace amountsin our atmosphere.  Its chemical formula isNH3.Which elements make up Ammonia?
Nitrous oxide
Hydroxide and Neon
Nitrogen and Hydrogen
Sodium and Helium
radiation
conduction
convection
solar
The diagram shows a bunsenburner heating a beakerof water on a stand.How is the heat being transferred to the beakerof water?
conduction
radiation
convection
biomass
Molten magma rises in 
Earth's mantle and then
sinks back toward the
core in a circular pattern
as shown in this diagram.
This method of heat 
transfer is known as:
a
b
d
