Antarctica
#6
What is the PDO (Pacific Decadal Oscillation) known for in relation to climate variability?
Causing volcanic eruptions
Affecting ocean currents in the Atlantic
Influencing temperature and precipitation patterns in the Pacific region
Inducing earthquakes along the Pacific Ring of Fire
#7
How do aerosols affect climate variability?
They increase cloud cover, leading to cooling effects.
They decrease albedo, leading to warming effects.
They absorb incoming solar radiation, leading to cooling effects.
They contribute to the greenhouse effect, leading to warming effects.
#8
What is the Intertropical Convergence Zone (ITCZ) and its significance in climate variability?
A region of high pressure at the equator, influencing global wind patterns
A zone where trade winds converge, affecting precipitation patterns
A phenomenon caused by the Earth's axial tilt, leading to seasonal changes
A region of low pressure in the polar areas, driving ocean currents
#9
What is the relationship between climate variability and extreme weather events?
Climate variability has no impact on extreme weather events.
Extreme weather events are entirely predictable due to climate variability.
Climate variability can exacerbate the frequency and intensity of extreme weather events.
Extreme weather events only occur during periods of stable climate.
#10
What role do glaciers play in climate variability?
Glaciers have no impact on climate variability.
Glaciers act as a buffer, regulating temperature changes in adjacent regions.
Glaciers contribute to sea level rise when they melt.
Glaciers release greenhouse gases when they melt.
#11
What is a teleconnection in the context of climate variability?
The process of transferring heat between the atmosphere and oceans
A statistical correlation between weather patterns at different locations
The interaction between human activities and climate systems
The movement of ocean currents driven by wind patterns
#12
Which of the following is NOT a potential impact of climate variability?
Changes in agricultural productivity
Increase in extreme weather events
Rise in sea level due to thermal expansion
Decrease in biodiversity
#13
What is the term for the gradual increase in Earth's average surface temperature due to human activities?
Global cooling
Anthropogenic climate change
Natural climate variability
Geothermal warming
#14
How do oceanic oscillations contribute to climate variability?
By redistributing heat around the globe through ocean currents
By absorbing excess carbon dioxide from the atmosphere
By increasing the albedo of ocean surfaces
By releasing aerosols into the atmosphere
#15
Which of the following is a positive feedback mechanism that amplifies climate variability?
Decrease in water vapor in the atmosphere

#17
How does deforestation contribute to climate variability?
Deforestation has no impact on climate variability.
Deforestation increases atmospheric carbon dioxide levels, leading to warming effects.
Deforestation promotes rainfall patterns, leading to cooling effects.
Deforestation reduces atmospheric humidity, leading to drought conditions.
