    If you find a piece of wood that has a mass of 59g and a volume of 100g/cm3, what kind of wood have you found? (Use Density=mass/volume)

    • A.

      Cherry

    • B.

      Walnut

    • C.

      Southern pine

    • D.

      Sugar maple

    Correct Answer
    B. Walnut
    Explanation
    The density of an object is defined as its mass per unit volume. By using the formula Density = mass/volume, we can determine the density of the given wood. The mass of the wood is 59g and the volume is 100g/cm3. Dividing the mass by the volume, we find that the density of the wood is 0.59 g/cm3. Comparing this value to the known densities of different types of wood, we can conclude that the wood in question is walnut.

  • 4. 

    Which items will float in water? 

    • A.

      Rubber

    • B.

      Mahogany

    • C.

      Aluminum

    • D.

      Pine

    Correct Answer(s)
    B. Mahogany
    D. Pine
    Explanation
    Mahogany and pine will float in water because they are both types of wood that have a lower density than water. When an object has a lower density than water, it displaces less water than its own weight, causing it to float. Rubber and aluminum, on the other hand, have higher densities than water, so they will sink.

    Mrs. Hubbard would like to investigate the impact of taking online practice tests on exam scores. She divided her classes up into 4 groups. Some did not take online practice tests, another group took the tests for 30 minutes, another for 60 minutes, and the last group for 90 minutes. What is the independent variable in this experiment?

    • A.

      The tests given to each group

    • B.

      The number of minutes taking online practice tests

    • C.

      The test scores

    • D.

      None of the above

    Correct Answer
    B. The number of minutes taking online practice tests
    Explanation
    The independent variable in this experiment is the number of minutes taking online practice tests. This is because the researcher is manipulating the duration of the practice tests to see how it impacts the exam scores. The other options listed are not being manipulated by the researcher and are therefore not considered independent variables in this experiment.

    Rate this question:

  • 6. 

    What is a sensible hypothesis for this experiment?

    • A.

      Test scores will affect how long a student studies online

    • B.

      If a student has higher grades, then they will study longer

    • C.

      If students spend a longer amount of time taking online practice tests, then their test score will be higher

    • D.

      Test scores will be affected by the speed of the internet

    Correct Answer
    C. If students spend a longer amount of time taking online practice tests, then their test score will be higher
    Explanation
    The hypothesis that states "If students spend a longer amount of time taking online practice tests, then their test score will be higher" is a sensible hypothesis for this experiment. It suggests that there is a relationship between the amount of time spent taking online practice tests and the resulting test score. This hypothesis can be tested by measuring the test scores of students who spend different amounts of time taking online practice tests and analyzing the data to determine if there is a correlation between time spent and test scores.

  • 10. 

    If CO2 continues to increase, what implications are there for Earth's overall climate?

    • A.

      The temperature would eventually stabilize and level off

    • B.

      The temperature will fluctuate unpredictably causing fluctuations of ice and melting

    • C.

      The temperature will continue to decrease causing the growth of polar ice caps

    • D.

      The temperature will continue to increase causing the melting of polar ice caps

    Correct Answer
    D. The temperature will continue to increase causing the melting of polar ice caps
    Explanation
    If CO2 continues to increase, it will lead to an increase in the Earth's overall temperature, which will cause the melting of polar ice caps. This is because the increased greenhouse gas concentration traps more heat in the atmosphere, leading to a rise in temperatures. As a result, the polar ice caps, which are sensitive to temperature changes, will melt. This will have significant implications for sea levels, ecosystems, and weather patterns around the world.

  • 11. 

    How does human activity affect the atmosphere?

    • A.

      Agriculture increases the amount of oxygen and nitrogen levels

    • B.

      The burning of fossil fuels increases the amount of CO2

    • C.

      Overpopulation increases water vapor from people exhaling

    • D.

      Humans do not have a significant impact on the atmosphere

    Correct Answer
    B. The burning of fossil fuels increases the amount of CO2
    Explanation
    Human activity, specifically the burning of fossil fuels, leads to an increase in the amount of carbon dioxide (CO2) in the atmosphere. Fossil fuels such as coal, oil, and natural gas release CO2 when burned for energy, contributing to the greenhouse effect and global warming. This increase in CO2 levels is a major factor in climate change and has significant impacts on the Earth's atmosphere, including altered weather patterns, rising sea levels, and the loss of biodiversity.

  • 12. 

    How is the nitrogen cycle different from the carbon cycle?

    • A.

      Carbon cycle occurs in the soil

    • B.

      The nitrogen cycle is dependent upon bacteria

    • C.

      The nitrogen cycle involves living and nonliving parts of the environment

    • D.

      The carbon cycle is only involved with living things

    Correct Answer
    B. The nitrogen cycle is dependent upon bacteria
    Explanation
    The nitrogen cycle is different from the carbon cycle because it is dependent upon bacteria. Nitrogen fixation, the process by which atmospheric nitrogen is converted into a form that can be used by plants, is mainly carried out by nitrogen-fixing bacteria. These bacteria convert nitrogen gas into ammonia, which can then be used by plants to synthesize proteins and other essential molecules. Without these bacteria, nitrogen would remain in its atmospheric form and would not be available for use by living organisms. In contrast, the carbon cycle does not rely on bacteria in the same way and involves different processes such as photosynthesis and respiration.

    Rate this question:

  • 13. 

    Check all statements that are true about the nitrogen cycle.

    • A.

      Humans get the nitrogen they need from food

    • B.

      Forest fires add nitrogen to the soil

    • C.

      Most of the air in the atmosphere is nitrogen

    • D.

      Plants get the nitrogen they need from air

    Correct Answer(s)
    A. Humans get the nitrogen they need from food
    B. Forest fires add nitrogen to the soil
    C. Most of the air in the atmosphere is nitrogen
    Explanation
    The given answer is correct. Humans get the nitrogen they need from food because nitrogen is an essential component of proteins, which are found in food. Forest fires add nitrogen to the soil because during a fire, nitrogen in organic matter is released as gases and particles, which eventually settle on the soil. Most of the air in the atmosphere is nitrogen, as nitrogen gas makes up about 78% of the Earth's atmosphere. Plants, on the other hand, do not get the nitrogen they need from air directly. They obtain nitrogen from the soil through their roots, where it is present in the form of nitrates or ammonium ions.

    Rate this question:

  • 14. 

    Which best describes the path of a nitrogen molecule through the nitrogen cycle?

    • A.

    • C.

      It moves through the different parts of the environment repeatedly and maybe in a different order

    • D.

      It moves through the different parts of the environment repeatedly and in the same order

    Correct Answer
    C. It moves through the different parts of the environment repeatedly and maybe in a different order
  • 15. 

    Which human activities would result in an increase in carbon in the atmosphere? 

    • A.

      Bicycling

    • B.

      Burning fossil fuels

    • C.

      Deforestation

    • D.

      Planting trees

    Correct Answer(s)
    B. Burning fossil fuels
    C. Deforestation
    Explanation
    Burning fossil fuels releases carbon dioxide into the atmosphere, contributing to the increase in carbon levels. Deforestation also leads to increased carbon in the atmosphere as trees absorb carbon dioxide and their removal reduces the amount of carbon being absorbed. Bicycling and planting trees do not directly result in an increase in carbon in the atmosphere.

    Rate this question:

  • 16. 

    The earth's atmosphere without carbon dioxide would be:

    • A.

      Much hotter

    • B.

      Much cooler

    • C.

      Not much different

    • D.

      Much windier

    Correct Answer
    B. Much cooler
    Explanation
    Without carbon dioxide in the Earth's atmosphere, the greenhouse effect would be significantly reduced. Carbon dioxide acts as a greenhouse gas, trapping heat from the sun and preventing it from escaping back into space. Therefore, without carbon dioxide, less heat would be trapped, resulting in a much cooler atmosphere.

    What can you conclude from the fact that there is the same amount of water on earth today as there was a billion years ago?

    • A.

      There will probably be the same amount of water a billion years from now

    • B.

      Water levels will continually fluctuate

    • C.

      There will be much less water a billion years from no

    • D.

      The water cycle will end and water will build up in one reservoir

    Correct Answer
    A. There will probably be the same amount of water a billion years from now
    Explanation
    The fact that there is the same amount of water on earth today as there was a billion years ago suggests that the water cycle is a continuous process. This implies that water is constantly being recycled and redistributed through various processes such as evaporation, condensation, and precipitation. Therefore, it is likely that there will be the same amount of water a billion years from now, as the water cycle will continue to replenish and maintain the water on earth.

    • B.

      Humans impact the carbon cycle but not the nitrogen cycle

    • C.

      Plants get both carbon and nitrogen from the atmosphere

    • D.

      Water plays an important role in both cycles

    Correct Answer
    D. Water plays an important role in both cycles
    Explanation
    Water plays an important role in both the nitrogen cycle and the carbon cycle. In the nitrogen cycle, water helps to dissolve and transport nitrogen compounds in the soil, allowing plants to absorb them through their roots. Water also facilitates the conversion of nitrogen gas in the atmosphere into a usable form through a process called nitrogen fixation. Similarly, in the carbon cycle, water is involved in the process of photosynthesis, where plants use water, carbon dioxide, and sunlight to produce glucose and oxygen. Water is essential for the movement of carbon dioxide in the atmosphere and the absorption of carbon by plants during photosynthesis.
