Final Weather Test
Name: ______________________________
1. The picture shows the water cycle.
In which part of the water cycle is water changing from a liquid to a gas?
A. Part 1
B. Part 2
C. Part 3
D. Part 4
The answer is A. Water from the reservoir which is a liquid, is turned into a gas (water vapor) by the sun, and rises into
the air.
2. In the morning, students observed puddles of water all over the playground. What would explain why the
playground was dry in the afternoon?
A. Animals drank the water
B. The wind stopped blowing
C. Someone dried the puddles
D. The water evaporated during the day
The answer is D. In the morning, the temperature would have been colder than in the afternoon. Since the
temperature became warmer in the afternoon, it is most likely that evaporation caused by the sun, made the water
disappear.
3. The water cycle describes the continuous movement of the water on the Earth. Which part of the cycle is directly
responsible for returning water to the soil?
A. Condensation
B. Evaporation
C. Precipitation
D. Transpiration
The answer is C. When water inside of clouds becomes too much, the water drops in the form of precipitation and
returns the water to the soil.
4.
A.
B.
C.
D.
Which of these could cause water vapor to condense into rain droplets?
Sunlight warming the surface of oceans
Air rising into colder regions of the atmosphere
Lightning heating the air in the atmosphere
Winds blowing along the surface of the ground
The answer is B. Air can contain water vapor. When the water vapor gets colder as it moves up into the troposphere, it
can turn into rain droplets and turn into clouds.
5.
A.
B.
C.
D.
Air in the atmosphere is heated unevenly by the sun, causing
Wind
Cloud formation
Volcanic Activity
Water condensation
The answer is A. If area of land is covered in dark grass, it will heat up faster and get hotter. A body of water next to it
will not get as hot and be cooler. Cool air sinks over the water, warm air rises over the land. This cycle (convection)
pushes air around in a cycle, causing wind.
6.
A.
B.
C.
D.
Which most likely contributes to the spinning pattern of a hurricane that develops over the ocean?
Gulf Stream
Coriolis Effect
Low Relative Humidity
High-Pressure Systems
The answer is B. The Coriolis Effect is the effect the Earth’s spin has on the winds. The spin causes the winds to curve or
spin.
7. The diagram shows the movement of air.
Which factor is most responsible for the movement of the air shown?
A. Uneven heating of the air/land
B. Imbalance in organisms breathing air
C. Sunlight getting blocked by the land
D. Waves and flooding
The answer is A. This is very similar to question six. The land is warmer causing air to rise. The warm air flows out to
the cooler air above the water and sinks. The cold air moves to the land, gets warm and rises.
8. What is the major cause of ocean waves?
A. Wind
B. Moon’s gravity
C. Salinity
D. Earth’s rotation
The answer is B. The Moon’s gravity pulls on the Earth and its water causing tides to be higher on two of the sides and
low tides on the other two side.
9. Winds blowing inland from oceans tend to have greater moisture than winds blowing over land. How does the high
moisture content affect the coastal area weather/climate?
A. These is less condensation
B. There are fewer hurricanes
C. There is greater precipitation
D. There are more smog-filled areas
The answer is C. If there is more moisture (water) in the air then there would most likely be more precipitation in the
areas that have that air.
10. What gas does wedge X represent?
A. Oxygen
B. Carbon Dioxide
C. Nitrogen
D. Water Vapor
The answer is C. The wedge represented by X is the largest piece of the pie. Nitrogen is the largest percentage of our
atmosphere.
11. Why is the ozone content of the stratosphere important to living organisms?
A. Ozone absorbs infrared radiation from the Sun.
B. Ozone absorbs ultraviolet radiations from the Sun.
C. Ozone is necessary to create oxygen for living things.
D. Ozone in the atmosphere prevents radiation of heat from Earth.
The answer is B. Ozone in the atmosphere absorbs UV light from the Sun, which helps protect us from too much UV
light that may cause things like cancer.
12. When compared to current average conditions, which term would best describe conditions in Earth’s lower
atmosphere is greenhouse gases (like CO2) were absent?
A. Denser
B. Cooler
C. Wetter
D. Cloudier
The answer is B. CO2 is like Earth’s blanket as it helps keep some the radiation that reflects off the ocean here on Earth.
Without it, the radiation would bounce out and not return to Earth, which would make it colder here.
13. In which layer of the atmosphere does most of Earth’s weather occur?
A.
B.
C.
D.
The exosphere, which is the outermost layer
The troposphere, which is the lowest layer
The thermosphere, which has the highest temperature
The stratosphere, which contains a sub-layer of ozone
The answer is B. This is the layer we live in and where weather occurs like thunderstorms and blizzards.
14. Space shuttles begin to encounter heat in the _____________________ because of the build up of friction between
the shuttle and the air molecules around them.
A. Stratosphere
B. Thermosphere
C. Troposphere
D. Mesosphere
The answer is D. The air thickens up in the mesosphere as the air density increases when you move towards Earth.
15. Put the five main layers of the atmosphere in order starting from the farthest from the ground to the surface of the
earth
A. troposphere, mesosphere, stratosphere, thermosphere, exosphere
B. exosphere, mesosphere, stratosphere, thermosphere, troposphere
C. exosphere, thermosphere, stratosphere, mesosphere, troposphere
D. exosphere, thermosphere, mesosphere, stratosphere, troposphere
The answer is D. The question asks you to start from the top of the atmosphere and move towards the Earth.
16. Fredrico is traveling higher and higher into the atmosphere in a hot air balloon. What is happening to the air
pressure around him?
A. It is increasing
B. It is decreasing
C. It is staying the same
D. It is increasing rapidly
The answer is B. Remember, that as you go higher in the atmosphere the pressure decreases. Think about a pile-on in
football. The guy at the bottom (the surface of the earth) feels more pressure. The guy at the top (the top of the
atmosphere) doesn’t feel as much pressure because he doesn’t have any bodies (air molecules) on top of him.
17. An air plane is flying at 45,000 feet when suddenly a dragon eats a hole in the side of the plane. The plane was
pressurized (filled with air) before the plane took off. What would most likely happen after the dragon ate the hole in
the plane?
A. Things would be sucked into the airplane
B. Things would be sucked out of the airplane
C. Nothing would go in or out of the air plane
D. None of the above
The answer is B. Since the plane was filled with air it would have more air molecules and would be an area of high
pressure. Since we know that as you go higher in the air the pressure drops, we can infer that the outside of the plane is
an area of low pressure. Areas of high pressure like to go to areas of low pressure. Therefore, everyone would be
sucked OUT of the plane.
18. Ke$ha runs through downtown during rush hour for 2 weeks straight during the middle of August where it is very
hot. After those weeks she starts complaining about her chest hurting to her doctor. She states that she never had any
chest pains when she ran in the country. What is most likely her problem?
A. Ground level ozone
B. Particle Pollution
C. Radiation from the sun
D. Noise pollution
The answer is A. The combination of exhaust pollution and the heat of the afternoon in August would create ground
level ozone.
80 Degrees (Frank)
30 Degrees
(Carlos)
19. In the diagram above who is standing in an area of high pressure and why?
A. Frank is because the warm temperature is causing the air molecules to become less dense and rise into the air.
B. Carlos is because the cold temperature is causing the air molecules to become more dense and sink down toward the
surface.
C. Frank is because the hot temperature is causing the air molecules to become more dense and sink down towards the
surface.
D. Carlos is because the cold temperature is causing the air molecules to become less dense and rise into the air.
The answer is B. The cold air above Carlos is sinking and causing an area of higher pressure.
20. In the diagram above, what is current season in example “C” for the southern hemisphere?
A. Summer
B. Winter
C. Spring
D. Fall
The answer is B. Since the southern hemisphere is tilted away from the sun, it is not receiving direct sunlight. This
makes the southern hemisphere colder.
21. What would happen if there were no tilt to the Earth?
A. There would be only 1 season all year long
B. There would be more than 4 seasons during the year
C. There would be the same amount of seasons as there is now
D. The world would fall into a period of deep cold
The answer is A. If the Earth did not have a tilt, each hemisphere would receive the same amount of sunlight all year.
22. In the diagram above what type of front is shown?
A. Cold Front
B. Warm Front
C. Occluded Front
D. Stationary Front
The answer is A. When a cold air mass hits a warm air mass and sinks underneath it, it is called a cold front.
23. What type of weather would likely occur at this front?
A. Light, steady rain
B. Thunderstorms/Severe weather
C. Light snow
D. Calm winds
The answer is B. Cold fronts cause warm air to rise up and create puffy cumulus clouds that can cause thunderstorms
and severe weather.
24. What clouds form when a warm air mass catches up with a cooler air mass and moves over it?
A. Cumulus
B. Cumulonimbus
C. Stratus
D. Cirrus
The answer is C. When a warm air mass hits a cold air mass it goes over the cold air mass. As it does this thin, layered
stratus clouds stretch over the cold air mass.
D
C
A
B
25. According to the temperature map above, where might you see severe weather?
A. A
B. B
C. C
D. D
The answer is A. Letter A shows an area where a cold air mass is combing with a warm air mass. This is a signal a cold
front may occur, which may cause severe weather.
