# Weather Review

```Weather Review
The layer of the atmosphere where
most weather takes place is…
a.
b.
c.
d.
The mesosphere
The thermosphere
The stratosphere
The troposphere
d. The troposphere
The troposphere is the layer of the atmosphere
closest to the Earth. This is where most
weather takes place.
What is the instrument that measures
the amount of water vapor in the air?
a.
b.
c.
d.
Anemometer
Barometer
Hygrometer
Thermometer
c. Hygrometer
The amount of water vapor in the air is the
humidity. The hygrometer measures how
humid the air is.
What instrument measures air
pressure?
a.
b.
c.
d.
Thermometer
Hygrometer
Anemometer
Barometer
d. Barometer
Think about the barometer demonstration in class
where the barometer was in a cup and we added
pressure to the top. As we pushed down on the
rubber top, the air pressure increased and you
were able to see the arrow on the barometer
move. The barometer was measuring the
amount of air pressure in the cup.
What instrument shows wind direction?
a.
b.
c.
d.
Wind vane
Anemometer
Barometer
Hygrometer
a. Wind vane
You can use the wind vane to determine which
direction the wind is coming from. This is why
all wind vanes have North, South, East, and
West labeled.
What instrument is used to measure
some kinds of precipitation?
a.
b.
c.
d.
Anemometer
Rain gauge
Barometer
Hygrometer
b. Rain gauge
Remember our discussion
the tools that many of your
families have outside to
measure how much rain
has fallen.
What instrument is used to measure
wind speed?
a.
b.
c.
d.
Wind vane
Barometer
Anemometer
Hygrometer
c. Anemometer
Remember the anemometer
is the tool that has the cups that spin
in the air. As the wind blows the cups
start spinning. The faster the cups
spin, the faster the wind is blowing.
What instrument is used to measure
temperature?
a.
b.
c.
d.
Barometer
Hygrometer
Thermometer
Rain gauge
c. Thermometer
Think about our discussions in math and science
used to measure the temperature of the air
around us.
What is the movement of air called?
a.
b.
c.
d.
Wind
Wind vane
Weather
A storm
a. Wind
Wind is the movement of air. You can create wind
by blowing out air. As you blow out air the air
around you has to move, too. This is an
example of wind.
The state of the atmosphere at a
certain place and time is…
a.
b.
c.
d.
Troposphere
Wind
Front
Weather
d. Weather
Weather is the state of the atmosphere at a certain
place and time. Think about how the weather is
different from one place to the next. The
weather we are experiencing in Bellevue today
is different from the weather they are
experiencing in Florida.
What is the boundary between two air
masses called?
a.
b.
c.
d.
Wind
Weather
Front
Troposphere
c. Front
Think about our discussion on cold and warm
fronts. When the two air masses meet, a front
is formed. This is what brings the changes in
weather.
Which is not a weather instrument?
a.
b.
c.
d.
Satellite
Stethoscope
Weather balloon
b. Stethoscope
A stethoscope is not a weather instrument. A
stethoscope is used by a doctor to check your
breathing, which is not related to weather.
Two temperature scales are…
a.
b.
c.
d.
Cumulus and Cirrus
Beaufort and Celsius
Stratus and Fahrenheit
Fahrenheit and Celsius
d. Fahrenheit and Celsius
Remember our discussions about temperature in
math and science. Fahrenheit is the
temperature scale we use in America. Celsius is
the temperature scale used in many other
countries.
Snow, rain, sleet, and hail are all
examples of ________.
a.
b.
c.
d.
Evaporation
Condensation
Precipitation
Weather fronts
c. Precipitation
Remember our discussions about the water cycle.
Water falling from the sky is precipitation.
Rain, hail, sleet, and snow are all examples of
precipitation.
Stratus clouds are…
a.
b.
c.
d.
Low and layered
High, wispy, and curled
Fluffy, big, and piled up
Whirling and funnel-shaped
a. Low and layered
with cotton balls. The
stratus clouds were
layers.
Clouds form when water vapor
changes to water droplets in the
air. What is this process called?
a.
b.
c.
d.
Precipitation
Evaporation
Water cycle
Condensation
d. Condensation
Think about our discussions of the water cycle.
Clouds are created as the water vapor changes
to water droplets. Remember, condensation
What is used to estimate wind speed?
a.
b.
c.
d.
A barometer
A hygrometer
The Beaufort scale
A thermometer
c. The Beaufort scale
Think about the handout with the pictures of the
effects of wind. This was an example of the
Beaufort scale. This scale is used to estimate
the speed of wind.
Air pressure is measured in…
a.
b.
c.
d.
Millibars
Degrees
Miles per hour
Feet
a. Millibars
Think about the barometers we looked at. The air
pressure is measured in millibars.
What is the movement of water on,
above, and below Earth’s surface
called?
a.
b.
c.
d.
Seasons
Precipitation
Water Cycle
Weather
c. Water Cycle
Remember the diagram we made of the water
cycle. The water moves from land to the air and
then back to land.
What two things about wind do
weather forecasters measure?
a.
b.
c.
d.
Pressure and temperature
Speed and humidity
Temperature and humidity
Speed and direction
d. Speed and direction
Remember our discussion of the different
instruments. The only two that are used to
measure wind are the anemometer and the
wind vane. The anemometer measures the
speed and the wind vane measures the
direction.
What is the name for the scientists
that study weather?
a.
b.
c.
d.
Meteorologist
Ecologist
Geologist
Paleontologist
a. Meteorologist
discusses meteorologists. These scientists
study the weather and help predict what is
going to happen next in the weather.
What kind of precipitation would
you have if the temperature was
18oF?
a.
b.
c.
d.
Rain
Sleet
Hail
Snow
d. Snow
If water freezes at 32oF, then it will be snowing.
What kind of pressure system
would create sunny, cloudless
days?
a. Low pressure
b. High pressure
b. High pressure
Remember our discussion about air pressure.
High pressure usually means sunny skies.
Think high = hot. When it is hot out the sun is
usually shining.
What tool do you use to measure
rain?
a.
b.
c.
d.
Snow board
Ruler

What tool do you use to measure
snow?
a.
b.

Rain gauge
Snow board
Hygrometer
c. Snow board
A snow board is used to measure how much snow
has fallen.
Why does the Earth
never run out of
rain?
We never run out of rain because of the water
cycle. Water is constantly moving through the
stages of the water cycle (evaporation,
condensation, precipitation).
Who was Gabriel
Fahrenheit?
Gabriel Fahrenheit was the scientist who invented
the Fahrenheit temperature scale. In the
Fahrenheit scale water freezes at 32o and boils at
212o.
Who was Anders
Celsius?
Anders Celsius was the scientist who developed
the Celsius temperature scale. In the Celsius
scale water freezes at 0o and boils at 100o.
Who was Sir Francis
Beaufort?
Sir Francis Beaufort created a wind scale to
measure wind strength.
Good luck on
