#1
Which of the following is a non-renewable resource?
Coal
ExplanationCoal is a fossil fuel formed from the remains of plants that lived and died millions of years ago, making it a non-renewable resource.
#2
What is the term used to describe the variety of life on Earth?
Biodiversity
ExplanationBiodiversity refers to the variety of life on Earth, including the diversity of species, ecosystems, and genetic variations.
#3
Which of the following is a greenhouse gas?
Carbon dioxide
ExplanationCarbon dioxide is a greenhouse gas that contributes to the greenhouse effect, trapping heat in the Earth's atmosphere.
#4
Which of the following is a renewable energy source?
Solar power
ExplanationSolar power, harnessed from the sun's energy, is a renewable resource that does not deplete over time.
#5
What is the main source of water pollution caused by human activities?
Industrial waste
ExplanationIndustrial waste, discharged into water bodies, is a significant source of water pollution resulting from human activities.
#6
Which of the following is a major cause of soil erosion?
Deforestation
ExplanationDeforestation, the removal of trees, is a significant cause of soil erosion as it reduces the protective cover and stability provided by vegetation.
#7
What is the term for the process of converting waste materials into reusable materials?
Recycling
ExplanationRecycling is the process of converting waste materials into reusable materials to reduce the consumption of new resources and minimize environmental impact.
#8
What is the primary cause of the hole in the ozone layer?
Chlorofluorocarbons (CFCs)
ExplanationChlorofluorocarbons (CFCs) are the primary cause of the hole in the ozone layer, leading to ozone depletion.
#9
Which of the following is a method of conserving water?
Fixing leaks promptly
ExplanationFixing leaks promptly is a water conservation method that helps reduce water waste and ensures efficient use of this essential resource.
#10
What is the primary cause of ozone depletion?
Chlorofluorocarbons (CFCs)
ExplanationChlorofluorocarbons (CFCs) are synthetic compounds that release chlorine, damaging the ozone layer and causing ozone depletion.
#11
Which international agreement aims to combat climate change?
Paris Agreement
ExplanationThe Paris Agreement is a global pact signed by countries to address climate change by limiting global temperature increases.
#12
What is the term used for the process by which an ecosystem changes over time due to disturbances?
Succession
ExplanationSuccession is the natural process of ecological change over time, often in response to disturbances, leading to a more stable ecosystem.
#13
What is the term used for the phenomenon where pollutants become more concentrated as they move up the food chain?
Biological magnification
ExplanationBiological magnification is the process where pollutants accumulate and become more concentrated as they move up the food chain, posing a threat to higher-level consumers.
#14
Which of the following is NOT a method for reducing carbon emissions?
Deforestation
ExplanationDeforestation, the clearing of forests, is not a method for reducing carbon emissions; instead, it contributes to increased atmospheric carbon levels.
#15
Which of the following is NOT a component of the 'reduce, reuse, recycle' approach?
Incinerating waste
ExplanationIncinerating waste is not a component of the 'reduce, reuse, recycle' approach; it involves burning waste, which can release harmful pollutants.
#16
What is the term for the sustainable use and management of Earth's natural resources?
Resource conservation
ExplanationResource conservation involves the responsible and sustainable use and management of Earth's natural resources to ensure their long-term availability.
#17
Which of the following is a common consequence of ocean acidification?
Loss of marine biodiversity
ExplanationOcean acidification, caused by increased carbon dioxide absorption, can lead to the loss of marine biodiversity and disruption of marine ecosystems.
#18
What is the term for the process of converting sunlight into electricity?
Solar photovoltaic
ExplanationSolar photovoltaic refers to the technology that converts sunlight into electricity, providing a clean and renewable energy source.
#19
What is the term for the process of using microorganisms to break down organic matter in waste?
Anaerobic digestion
ExplanationAnaerobic digestion is a process that uses microorganisms to break down organic matter in waste, producing biogas and nutrient-rich byproducts.
#20
Which of the following is a consequence of deforestation?
Increased soil erosion
ExplanationDeforestation leads to increased soil erosion, as the removal of trees reduces soil stability and increases the risk of erosion.
#21
Which of the following is a characteristic of a sustainable resource management system?
Utilizing resources at a rate that allows natural regeneration
ExplanationA sustainable resource management system involves using resources in a way that allows for natural replenishment and long-term environmental health.
#22
What is the term used for the process of restoring degraded, damaged, or destroyed ecosystems?
Restoration
ExplanationRestoration involves the process of repairing and returning ecosystems to a healthier state after being degraded, damaged, or destroyed.
#23
Which of the following is NOT a greenhouse gas?
Oxygen
ExplanationOxygen is not a greenhouse gas; greenhouse gases trap heat in the atmosphere, and oxygen does not contribute to this effect.
#24
Which of the following is a method of sustainable agriculture?
Agroforestry
ExplanationAgroforestry is a sustainable agriculture method that integrates trees and shrubs into farming systems, promoting biodiversity and enhancing environmental sustainability.
#25
What is the term for the protection, preservation, management, or restoration of natural environments and the ecological communities that inhabit them?
Conservation
ExplanationConservation involves the protection, preservation, management, or restoration of natural environments and the ecological communities within them, aiming to maintain biodiversity and ecosystem health.
