This test is to gauge your knowledge of topics surrounding weather.


Questions and Answers
  • 1. 

    Earth’s weather is primarily caused by the 

    • A.

      Drifting of Earth's crustal plates

    • B.

      Gravitational attraction of the Moon

    • C.

      Uneven heating of Earth's surface

    • D.

      Changing between Earth and the Sun

    Correct Answer
    C. Uneven heating of Earth's surface
    Explanation
    The correct answer is "uneven heating of Earth's surface." This is because the uneven distribution of solar energy on Earth's surface leads to variations in temperature and pressure, which in turn drive the movement of air masses and the formation of weather systems such as wind, clouds, and precipitation. The differential heating of land and water, as well as the tilt of Earth's axis, also play a role in creating different climate zones and seasonal weather patterns.

    The weather map below shows the locations of a high-pressure center (H) and a low-pressure center (L), air masses cP and mT, and city A. Explain why city A has clear sky conditions. [1]

    Correct Answer
    City A is near a high-pressure system
    City A is located in a cold, dry air mass.
    City A is located behind a cold front
    Explanation
    City A has clear sky conditions because it is near a high-pressure system. High-pressure systems are associated with sinking air, which inhibits cloud formation and leads to clear skies. Additionally, City A is located in a cold, dry air mass. Cold air can hold less moisture, reducing the likelihood of cloud formation. Lastly, City A is located behind a cold front. Cold fronts often bring drier air behind them, leading to clear skies.

    Base your answers to the following questions on the information below and on your knowledge of science. The diagram shows a person observing a thunderstorm located several kilometers away. The person hears the thunder several seconds after seeing the lightning. Identify a form of energy, other than light and sound, that is often present during a thunderstorm. [1]

    Correct Answer
    heat energy
    thermal energy
    electrical energy
    wind energy
    electromagnetic energy
    potential energy
    kinetic energy
    static electricity
    Explanation
    During a thunderstorm, there is often the presence of electrical energy. This is because thunderstorms are caused by the buildup of electrical charges in the atmosphere, resulting in the discharge of lightning. The electrical energy is generated by the movement of electrons between the positively and negatively charged areas in the storm clouds.

    A wet shirt is put on a clothesline to dry on a sunny day. The shirt dries because water molecules 

    • A.

      Gain heat energy and condense

    • B.

      Gain heat energy and evaporate

    • C.

      Lose heat energy and condense

    • D.

      Lose heat energy and evaporate

    Correct Answer
    B. Gain heat energy and evaporate
    Explanation
    When a wet shirt is exposed to the sun, the heat energy from the sun is transferred to the water molecules in the shirt. This increased heat energy causes the water molecules to gain enough energy to overcome the forces holding them together, and they evaporate into the air as water vapor. This process of gaining heat energy and evaporating leads to the drying of the shirt.

    How should the students be placed in the room to represent the arrangement of particles in a solid? [1]

    Correct Answer
    very close together
    tightly packed
    touching
    close
    Explanation
    The students should be placed in the room very close together, tightly packed, touching, and close to represent the arrangement of particles in a solid. In a solid, the particles are closely packed together and have very little space between them. They are in constant contact with each other, which gives solids their rigidity and fixed shape. Therefore, placing the students in the room in a similar manner would accurately depict the arrangement of particles in a solid.

    Rate this question:

  • 9. 

    What instruction should be given to the 20 student “particles” to show the addition of heat to the “solid sample of matter”? (Note: The solid is simply being heated; it should not melt.) [1] 

    Correct Answer
    move the students a little further apart
    tell the students to start wiggling in place
    ask the students to bump into each other
  • 10. 

    What instruction should be given to the 20 student “particles” to represent a liquid? [1] 

    Correct Answer
    moving around the room
    changing their position in the sample
    move a lot further apart
    move around faster than a solid
    Explanation
    The instruction to the 20 student "particles" to represent a liquid would be to move around the room, change their position in the sample, move a lot further apart, and move around faster than a solid. This is because in a liquid, the particles are constantly moving and changing their positions. They are also more spread out compared to particles in a solid and they move faster than solid particles.

    Rate this question:

  • 11. 

    During which phase change is heat energy absorbed by a substance?

    • A.

      Liquid to gas

    • B.

      Gas to solid

    • C.

      liquid to solid

    • D.

      Gas to liquid

    Correct Answer
    A. Liquid to gas
    Explanation
    During the phase change from liquid to gas, heat energy is absorbed by the substance. This is because the particles in a liquid have less kinetic energy compared to the particles in a gas. When heat is added to the liquid, the particles gain energy and move faster, eventually breaking the intermolecular forces holding them together. This process is called vaporization or evaporation, and it requires heat energy to overcome the attractive forces between the molecules and change the substance from a liquid to a gas.

    The diagram below shows a Bunsen burner heating a beaker of water on a  beaker stand.  The arrows represent the transfer of heat energy in the water. Which process is primarily responsible for the transfer of heat indicated by the  arrows in the beaker of water?

    • A.

      Conduction

    • B.

      Convection

    • C.

      Radiation

    • D.

      Condensation

    Correct Answer
    B. Convection
    Explanation
    The arrows in the diagram indicate the transfer of heat energy in the water. Convection is the process primarily responsible for this transfer. Convection occurs when heat is transferred through the movement of a fluid, in this case, the water in the beaker. As the water near the bottom of the beaker is heated by the Bunsen burner, it becomes less dense and rises, creating a convection current. This current causes the heated water to move upwards, while the cooler water near the top of the beaker moves downwards. This movement of the fluid transfers heat energy throughout the water in the beaker.

    Base your answers to the following question on the diagram below and on your knowledge of science. The diagram shows a model of the water cycle. Explain why the level of the muddy water will decrease slightly if the model is left in a sunny location for several days. [1]

    Correct Answer
    the water will evaporate
    Water will change from a liquid to a gas
    The water will evaporate, condense, and go into the glass
    Explanation
    The level of the muddy water will decrease slightly if the model is left in a sunny location for several days because the water will evaporate. Evaporation is the process in which water changes from a liquid to a gas. The heat from the sun causes the water molecules to gain energy and become vapor, leading to a decrease in the water level. Additionally, the evaporated water may condense and go into the glass, further contributing to the decrease in the water level.

    The graph below shows the heating curve for substance X. At approximately which temperature does a phase change begin?

    • A.

      - 30°C

    • B.

      -10°C

    • C.

      0°C

    • D.

      18°C

    Correct Answer
    B. -10°C
    Explanation
    The phase change begins at approximately -10°C. This can be determined by looking at the graph and identifying the point where there is a sudden change in the slope of the curve. At this temperature, the substance X transitions from one phase to another, which is indicated by the phase change.

    Base your answers to questions 60 and 61 on the diagram below and on your knowledge of science. The diagram shows a sequence of events. The ball and ring are made of the same metal. Describe what can be done so that the metal ball will again go through the ring.

    Correct Answer
    cool the metal ball
    heat the metal ring
    Explanation
    When a metal object is heated, it expands, and when it is cooled, it contracts. In this scenario, cooling the metal ball will cause it to contract, making it smaller in size. On the other hand, heating the metal ring will cause it to expand, making the hole in the ring larger. By cooling the ball and heating the ring, the size of the ball will be reduced, allowing it to pass through the expanded ring.

    The average daily air temperature at a certain location increases when there is a seasonal increase in the number of daylight hours. Which graph best shows this change?

    Correct Answer
    A.  
    Explanation
    The graph that best shows the change in average daily air temperature with a seasonal increase in the number of daylight hours would be a line graph with the x-axis representing time (months or days) and the y-axis representing temperature. The graph should show a gradual increase in temperature as the number of daylight hours increases.

    The diagram below shows a tall beaker with four different liquids and their densities. If a ball that has a density of 1.73 g/cm3 is placed in the beaker, where will the ball come to rest?

    • A.

      On top of liquid A

    • B.

      Between liquids B and C

    • C.

      Between liquids C and D

    • D.

      On the bottom of the beaker

    Correct Answer
    C. Between liquids C and D
    Explanation
    Based on the given information about the densities of the liquids in the beaker, the ball will come to rest between liquids C and D. This is because the ball's density is higher than the densities of liquids A and B, so it will sink below them. However, the ball's density is lower than the density of liquid D, so it will not sink to the bottom of the beaker. Therefore, the only option left is for the ball to come to rest between liquids C and D.
