#1
Which of the following is a greenhouse gas?
Carbon Dioxide
ExplanationCarbon dioxide is a well-known greenhouse gas contributing to global warming.
#2
What is the primary cause of global warming?
Greenhouse gas emissions
ExplanationEmissions of greenhouse gases, primarily from human activities, are the main drivers of global warming.
#3
Which gas is the most abundant in Earth's atmosphere?
Nitrogen
ExplanationNitrogen constitutes the largest proportion of Earth's atmosphere by volume.
#4
What is the term for the gradual increase in Earth's average temperature over time?
Global warming
ExplanationGlobal warming refers to the long-term rise in Earth's average temperature due to human activities.
#5
What is the main greenhouse gas emitted by human activities?
Carbon Dioxide
ExplanationCarbon dioxide is the primary greenhouse gas released by human activities such as burning fossil fuels.
#6
Which layer of the atmosphere contains the ozone layer?
Stratosphere
ExplanationThe ozone layer resides in the stratosphere of the Earth's atmosphere.
#7
What is the term for the process by which water vapor turns into liquid water?
Condensation
ExplanationCondensation is the phase transition of water vapor into liquid water.
#8
Which of the following is a major greenhouse gas emitted by agricultural activities?
Methane
ExplanationMethane is a potent greenhouse gas released during various agricultural practices.
#9
What is the primary source of energy driving the Earth's climate system?
Solar radiation
ExplanationSolar radiation from the Sun is the primary energy source influencing Earth's climate system.
#10
What is the name for the process of a glacier breaking off into the ocean?
Calving
ExplanationCalving refers to the process of glaciers breaking off into the ocean, forming icebergs.
#11
What is the name of the phenomenon where Earth's average temperature gradually increases due to human activities?
Climate change
ExplanationClimate change refers to the long-term alteration of Earth's climate patterns, predominantly caused by human activities.
#12
Which of the following is a consequence of ocean acidification?
Coral bleaching
ExplanationOcean acidification, resulting from increased carbon dioxide absorption, leads to coral bleaching.
#13
What is the main contributor to the hole in the ozone layer?
Chlorofluorocarbons (CFCs)
ExplanationChlorofluorocarbons (CFCs) are synthetic compounds primarily responsible for ozone depletion in the atmosphere.
#14
Which of the following phenomena is associated with the release of greenhouse gases from permafrost?
Methane clathrate release
ExplanationThe release of methane clathrates from permafrost contributes to greenhouse gas emissions and exacerbates climate change.
#15
What is the name for the process of the Earth's surface heating up due to the trapping of heat by greenhouse gases?
Enhanced greenhouse effect
ExplanationThe enhanced greenhouse effect occurs when increased greenhouse gas concentrations trap more heat in the Earth's atmosphere, leading to surface warming.
