What is the primary cause of climate variability?

  1. Solar radiation

  2. Volcanic eruptions

  3. Ocean currents

  4. Human activities


Correct Option: C
Explanation:

Ocean currents play a significant role in redistributing heat around the globe, influencing regional climate patterns and causing climate variability.

Which phenomenon is characterized by unusually high temperatures over a sustained period?

  1. Heat wave

  2. Cold wave

  3. Drought

  4. Flood


Correct Option: A
Explanation:

A heat wave is a period of abnormally high temperatures that can last for days or weeks, often leading to adverse health effects and environmental impacts.

What is the term for a prolonged period of below-average precipitation?

  1. Drought

  2. Flood

  3. Heat wave

  4. Cold wave


Correct Option: A
Explanation:

Drought refers to a period of abnormally dry weather that can lead to water shortages, crop failures, and ecological disturbances.

Which climate extreme involves the rapid onset of heavy rainfall, leading to flooding and landslides?

  1. Hurricane

  2. Tornado

  3. Flood

  4. Drought


Correct Option: C
Explanation:

Floods occur when water overflows land areas, often caused by heavy rainfall, storm surges, or dam failures.

What is the term for a severe storm characterized by high winds and heavy rainfall, often accompanied by thunder and lightning?

  1. Hurricane

  2. Tornado

  3. Flood

  4. Drought


Correct Option: A
Explanation:

Hurricanes are intense tropical cyclones that form over warm ocean waters and bring strong winds, heavy rain, and storm surges.

Which climate extreme involves a rapidly rotating column of air that extends from the base of a thunderstorm cloud to the ground?

  1. Hurricane

  2. Tornado

  3. Flood

  4. Drought


Correct Option: B
Explanation:

Tornadoes are destructive atmospheric vortices that can cause significant damage and loss of life.

What is the primary factor contributing to the rise in global average temperatures observed in recent decades?

  1. Solar radiation

  2. Volcanic eruptions

  3. Ocean currents

  4. Human activities


Correct Option: D
Explanation:

Human activities, particularly the burning of fossil fuels, have led to increased greenhouse gas emissions, resulting in the trapping of heat in the atmosphere and contributing to global warming.

Which international agreement aims to limit global temperature rise and address climate change?

  1. Kyoto Protocol

  2. Paris Agreement

  3. Montreal Protocol

  4. Stockholm Convention


Correct Option: B
Explanation:

The Paris Agreement is a legally binding international treaty on climate change, adopted in 2015, that aims to limit global warming and enhance climate resilience.

What is the term for the gradual shift in the average climate conditions over a long period, typically decades or centuries?

  1. Climate variability

  2. Climate change

  3. Climate extremes

  4. Global warming


Correct Option: B
Explanation:

Climate change refers to long-term shifts in temperature, precipitation, and other climate patterns, often attributed to human activities and natural processes.

Which phenomenon involves the rapid intensification of a tropical cyclone, often leading to catastrophic damage?

  1. Rapid intensification

  2. Storm surge

  3. Eye of the storm

  4. Wind shear


Correct Option: A
Explanation:

Rapid intensification is a process in which a tropical cyclone undergoes a sudden and significant increase in wind speed and organization, often leading to devastating impacts.

What is the term for the temporary increase in global average temperatures that occurs every few decades?

  1. El Niño

  2. La Niña

  3. Southern Oscillation

  4. North Atlantic Oscillation


Correct Option: A
Explanation:

El Niño is a climate phenomenon characterized by unusually warm ocean temperatures in the central and eastern Pacific Ocean, leading to changes in weather patterns worldwide.

Which climate extreme involves a sudden and intense winter storm characterized by heavy snow, strong winds, and low visibility?

  1. Blizzard

  2. Ice storm

  3. Winter storm

  4. Polar vortex


Correct Option: A
Explanation:

Blizzards are severe snowstorms with strong winds and low visibility, often leading to travel disruptions and hazardous conditions.

What is the term for the phenomenon where the jet stream, a high-altitude wind current, becomes distorted and wavy, leading to extreme weather events?

  1. Polar vortex

  2. Jet stream distortion

  3. Atmospheric blocking

  4. Rossby waves


Correct Option: B
Explanation:

Jet stream distortion occurs when the jet stream deviates from its typical path, resulting in extreme weather events such as heat waves, cold spells, and heavy precipitation.

Which climate extreme involves a prolonged period of unusually cold temperatures, often accompanied by snow and ice storms?

  1. Cold wave

  2. Heat wave

  3. Drought

  4. Flood


Correct Option: A
Explanation:

Cold waves are periods of abnormally low temperatures that can lead to hypothermia, frostbite, and disruptions to daily life.

What is the term for the phenomenon where the ocean absorbs and releases large amounts of heat, influencing global climate patterns?

  1. Ocean heat content

  2. Ocean currents

  3. Ocean acidification

  4. Sea level rise


Correct Option: A
Explanation:

Ocean heat content refers to the amount of heat stored in the ocean, which plays a crucial role in regulating global climate and influencing weather patterns.
