Final Jeopardy
Energy in the Atm. for 100
Energy from the sun travels as ____________
waves which reaches Earth’s surface as visible
light, ____________ radiation (which helps heat
Earth’s atmosphere), and some _______________
radiation.
Electromagnetic waves, infrared radiation, and
SOME ultraviolet radiation.
Energy in the Atm. for 200
The energy from the sun enters Earth’s
atmosphere and is ____________ or
____________ by clouds, gas molecules,
and solid particles in the air.
absorbed or reflected
Energy in the Atm. for 300
Some sunlight, especially the shorter
wavelengths of sunlight can be
___________, or reflected in all directions.
scattered
Energy in the Atm. for 400
What is the greenhouse effect?
The process by which gas molecules trap
heat that is radiated from Earth’s
surface.
Energy in the Atm. for 500
Explain why the air over land contains warmer air
than the air over water during the daytime.
The ground heats up more quickly than water
does. So, when the ground gives off heat, the air
above it is heated. On the other hand, the air
above the water is cooler because the water does
NOT heat up or cool down as quickly as the
ground does.
Heat Transfer for 100
The average energy of motion of the
molecules of a substance is called
_____________.
temperature
Heat Transfer for 200
Heat transfer by contact (such as touching a
hot stove accidentally) is called
_____________.
conduction
Heat Transfer for 300
If you place your hands near a light source
(such as a lamp), your hands will be heated
by which method of heat transfer?
Radiation
Heat Transfer for 400
Explain how a thermometer works (how
temperature is measured).
As the liquid inside the thermometer is
heated, its molecules move faster and the
liquid begins to expand. The liquid then
rises in the tube of the thermometer to
give a higher temperature reading.
Heat Transfer for 500
Which method of heat transfer is the main way by
which the troposphere is heated? Explain how this
type of heat transfer heats up the troposphere.
Convection: warm air rises, cold air sinks
which is then heated by the heat given off by
the surface. So, this warmed air rises. Then
the cycle continues and the troposphere gets
warmer and warmer.
Winds for 100
Winds are caused by an unequal heating of
Earth’s surface which causes ____________
differences.
pressure
Winds for 200
Wind speed is measured with a(n)
______________, and the increased cooling
that the wind can cause is called the
______________.
Anemometer
Wind chill factor
Winds for 300
What are global winds and why do they
curve (what is the name of this effect)?
Global winds are winds that blow from
specific directions over long distances.
They curve because of the Coriolis Effect,
which is due to Earth’s rotation.
Winds for 400
Explain how winds form.
There is an unequal heating of the atmosphere
that causes air to be warmer over some areas
and colder over others. As warm air rises it
creates an area of low pressure, then cooler air
that exerts a higher pressure comes in
underneath the warm air.
Winds
DAILY DOUBLE!!!
Explain how a land breeze forms. Does a land
breeze occur during the day or night?
At night, the ground cools off more quickly
than the water, so there is cooler air over the
land and warmer air over the water. The
warmer air over the water rises (creating an
area of low pressure) and the cooler air moves
in underneath the warm air from the land.
Water in the Atm. for 100
What are the 3 processes of the water cycle
(in order)?
evaporation, condensation, precipitation
Water in the Atm. for 200
Briefly describe the the 3 major types of
clouds.
Cirrus- wispy, feathery clouds that are
made up of ice crystals
Cumulus- fluffy, indicate fair weather
Stratus- flat-layered clouds that are a
dull gray color and cover much of the sky
Water in the Atm. for 300
What is relative humidity and how is it measured?
Relative humidity is the percentage of water
vapor in the air compared to the maximum
amount of water vapor the air can hold at a
certain temperature.
It is measured with a psychrometer, which
contains a dry bulb and a wet bulb
thermometer. The difference between the
temperatures of these thermometers is used to
determine the relative humidity.
Water in the Atm.
DAILY DOUBLE!!!
If the relative humidity is 100%, then what has to
be true about the dry and wet bulb temperatures?
(same?, different?) Explain why this is the case.
Temperatures are the same because the water
will not evaporate due to the excess moisture in
the air. Therefore, the wet bulb thermometer
will not cool down, so the temperatures are the
same.
Water in the Atm. for 500
Describe how liquid water from a stream can form a
cloud. Be sure to include the 2 conditions that are
required for clouds to form.
As the sun heats the liquid water, it turns into water
vapor and rises in the atmosphere. As it rises, it
cools enough to condense onto the solid particles in
the air to form clouds.
Applying Concepts for 100
If it is cloudy out for an entire day, will the
temperature change much throughout the
day? Explain why or why not.
No, because the clouds will reflect the
sun’s energy, so the troposphere will not
be heated all that much.
Applying Concepts for 200
Which global wind belt is important for the
weather in the United States?
Prevailing Westerlies
Applying Concepts for 300
If you walked into a warm building during the
winter, how would the relative humidity change
(higher or lower)? Explain why. What about the
reverse of this?
Lower, because warm air can hold more water
vapor as cold air.
A cold building would have a higher relative
humidity on a warm day.
Applying Concepts for 400
Suppose you went on 3 different journeys using the 3
major global wind belts. Match up the global wind
belt with the appropriate journey: away from the
North pole, from southern Europe to South America,
and from Cuba to England.
Polar Easterlies- Away from the North Pole
Trade Winds- From Europe to South America
Prevailing Westerlies- Cuba to England
Applying Concepts for 500
Based upon what you should know about heat
transfer in the troposphere, explain why the air a
few centimeters above the ground would be
slightly warmer than the air 300 centimeters above
the ground during the daytime.
The ground gives off heat during the day, and
this heat is transferred by conduction to the gas
molecules closest to Earth’s surface, making the
air warmer there than higher up.
Real World for 100
Which type of wind can change direction
day to day (global or local)?
Local winds can change direction from
day to day.
Real World for 200
Mist and drizzle are forms of precipitation that are
composed of water droplets. The amount of
another form of precipitation, rain, is measured
with a ________________.
Rain gauge measures rainfall
Real World for 300
On average, a snowfall of 80 centimeters would
produce how many centimeters of rainfall?
8 centimeters
Real World for 400
A wind vane measures wind direction. Which way does a
wind vane point (the direction the wind is coming from OR
the direction the wind is blowing)? Which direction would
a wind vane point for a North wind? Hint: A North wind
blows from the _____________ toward the
______________.
A wind vane points in the direction the wind is coming
from.
A North wind blows from the North toward the South,
so the wind vane would point towards the North.
Real World for 500
What is the difference between sleet and freezing
rain? Describe how they form.
Freezing rain forms when rain hits a cold
surface that is below freezing, which causes the
water to freeze on contact with the cold surface.
This creates ice on the cold surface.
Sleet is when rain falls through a layer of air
that is below freezing and forms ice that falls to
Earth’s surface.
Heat Transfer
Explain how the troposphere is heated by all three
methods of heat transfer.
Radiation from the sun and from Earth’s surface
transfer heat into the atmosphere via electromagnetic
waves.
Conduction heats the troposphere when the Earth’s
surface gives off heat and this heat is absorbed by the
gas molecules closest to Earth’s surface.
Convection heats the troposphere by warm air rising
and cold air sinking, then the cold air is warmed by the
heat given off by Earth’s surface.
