    Which of the following is NOT an ozone-depleting substance?

    • A.

      Pesticides

    • B.

      Isopropyl alcohol

    • C.

      Substances in fire extinguishers

    • D.

      Substances in air conditioners

    Correct Answer
    B. Isopropyl alcohol
    Explanation
    Isopropyl alcohol is not an ozone-depleting substance because it does not contain chlorine or bromine, which are the primary components responsible for ozone depletion. Ozone-depleting substances, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), release chlorine and bromine atoms into the atmosphere, which then react with ozone molecules and break them down. Isopropyl alcohol, on the other hand, does not contain chlorine or bromine and therefore does not contribute to ozone depletion.

      Habitat alteration or destruction

    • B.

      Excessive mining

    • C.

      Forest fires

    • D.

      Global warming

    Correct Answer
    A. Habitat alteration or destruction
    Explanation
    Biodiversity loss can lead to habitat alteration or destruction, as the loss of different species can disrupt the delicate balance of ecosystems. When certain species disappear, it can affect the availability of food, shelter, and other resources for other organisms, leading to changes in the physical structure and composition of habitats. This can have cascading effects on the entire ecosystem, potentially causing the loss of other species and reducing overall biodiversity. Habitat alteration or destruction is a significant consequence of biodiversity loss and can have far-reaching environmental impacts.

    The Law of ________________ states that energy cannot be created nor destroyed.

    Correct Answer
    conservation of energy
    Explanation
    The Law of Conservation of Energy states that energy cannot be created nor destroyed. This principle is based on the understanding that energy can only be transferred or transformed from one form to another. In other words, the total amount of energy in a closed system remains constant over time. This law is a fundamental concept in physics and is supported by numerous experimental observations and mathematical equations. It has wide-ranging applications in various fields, including mechanics, thermodynamics, and electromagnetism.

    Trees decrease the level of oxygen in the atmosphere.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    This statement is false. Trees actually increase the level of oxygen in the atmosphere through the process of photosynthesis. During photosynthesis, trees absorb carbon dioxide and release oxygen as a byproduct. Therefore, trees play a crucial role in maintaining the oxygen levels in the atmosphere and are often referred to as the "lungs of the Earth".

    Many of these are generally not destroyed in use and can be recycled.

    Correct Answer
    minerals
    mineral
    Explanation
    Minerals are generally not destroyed in use and can be recycled. This is because minerals are naturally occurring substances that are formed through geological processes and are not easily broken down or destroyed by human activities. Additionally, minerals can be extracted from the earth and processed to create new products, making them a valuable resource that can be reused and recycled.

    Rate this question:

  • 9. 

    One of the causes of resource depletion is the non-equitable distribution of resources.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement suggests that resource depletion occurs when resources are not distributed fairly or equally among individuals or regions. This means that some areas or groups may have access to more resources than they actually need, while others may not have enough to sustain themselves. This unequal distribution can lead to overconsumption and exploitation of resources in certain areas, ultimately resulting in resource depletion. Therefore, the given answer, "True," is correct.

    Which layer absorbs almost all the ultraviolet radiation that reaches the earth?

    • A.

      Atmosphere

    • B.

      Greenhouse gases

    • C.

      Stratospheric ozone

    • D.

      Tropospheric ozone

    Correct Answer
    C. Stratospheric ozone
    Explanation
    The stratospheric ozone layer absorbs almost all the ultraviolet radiation that reaches the earth. This layer is located approximately 10 to 50 kilometers above the earth's surface and contains a high concentration of ozone molecules. Ozone is a molecule made up of three oxygen atoms and has the ability to absorb and scatter UV radiation. This absorption process prevents most of the harmful UV radiation from reaching the earth's surface, protecting living organisms from its damaging effects.

    This happens when climate changes due to global warming.

    • A.

      More frequent typhoons

    • B.

      Ice melts and islands disappear

    • C.

      Water in the oceans warms and expands

    • D.

      All of these

    Correct Answer
    D. All of these
    Explanation
    The given answer, "All of these," is correct because when climate changes, several effects can occur. More frequent typhoons can result from changes in weather patterns, as warmer ocean temperatures can fuel the formation of these storms. Additionally, climate change can cause ice to melt, leading to the disappearance of islands. Furthermore, as the Earth's temperature rises, the water in the oceans warms and expands, contributing to sea level rise. Therefore, all of the mentioned effects can happen when climate changes.

    Rate this question:

  • 12. 

    Which is NOT true about non-renewable resources?

    • A.

      They are finite or non-sustainable.

    • B.

      Their exploitation and use will eventually lead to their exhaustion.

    • C.

      They cannot be stored for future use.

    • D.

      These resources take millions of years to form.

    Correct Answer
    C. They cannot be stored for future use.
    Explanation
    Non-renewable resources are finite or non-sustainable, meaning that they cannot be replenished at a rate that matches their consumption. Their exploitation and use will eventually lead to their exhaustion because they are not being replaced. Additionally, these resources take millions of years to form, further emphasizing their limited availability. However, it is not true that non-renewable resources cannot be stored for future use. In fact, many non-renewable resources, such as fossil fuels, are commonly stored and used as energy sources when needed.

    Correct Answer
    A. El Niño
    Explanation
    El Niño refers to the extreme warming of the central and eastern Pacific. During an El Niño event, the ocean temperatures in this region become unusually warm, disrupting the normal weather patterns and leading to various impacts around the world. These impacts can include heavy rainfall in some areas, droughts in others, and changes in temperature and wind patterns. El Niño events typically occur every few years and can last for several months. Understanding and monitoring El Niño is important for predicting and managing its effects on weather and climate.

    This refers to the atmospheric disturbance and recurrent ocean warming.

    • A.

      El Niño Southern Oscillation

    • B.

      La Niña Southern Oscillation

    • C.

      C. Typhoons, Hurricanes, Cyclones

    • D.

      D. Both A and B

    Correct Answer
    A. El Niño Southern Oscillation
    Explanation
    El Niño Southern Oscillation (ENSO) refers to the atmospheric disturbance and recurrent ocean warming. It is a climate pattern that occurs across the tropical Pacific Ocean, affecting weather conditions worldwide. During El Niño, the ocean temperatures in the eastern Pacific become warmer than usual, leading to changes in atmospheric circulation and rainfall patterns. La Niña, on the other hand, is the opposite phase of ENSO, characterized by cooler ocean temperatures in the eastern Pacific. Both El Niño and La Niña have significant impacts on global weather patterns, including the intensity and frequency of typhoons, hurricanes, and cyclones. Therefore, the correct answer is El Niño Southern Oscillation.

    It is the "mark" that you leave in the environment each time you use fossil fuel. 

    Correct Answer
    carbon footprint
    Explanation
    The term "carbon footprint" refers to the impact or amount of greenhouse gases, particularly carbon dioxide, that are emitted into the atmosphere as a result of an individual, organization, or activity. It is essentially the measure of the environmental impact caused by the use of fossil fuels. The more fossil fuels are used, the higher the carbon footprint, indicating a greater contribution to climate change and environmental degradation.
