What environmental phenomenon is characterized by severe or unusual weather conditions?

• A. Climate change
• B. Extreme weather
• C. Natural disasters
• D. Seasonal variations

Answer: (B)

Extreme weather refers to significant deviations from typical weather patterns, including severe phenomena such as hurricanes, tornadoes, heatwaves, and heavy snowfall. These conditions are marked by their intensity, duration, and potential to cause harm to the environment and human society.

This concept is directly tied to observable weather events that stand out due to their severity. For example, an extreme weather event might include a record-breaking storm that produces heavy rainfall resulting in flooding or unusually high temperatures that lead to drought conditions. These events can be influenced by longer-term climate trends, such as climate change, but the term "extreme weather" specifically focuses on the short-term weather phenomena that are more intense or unusual than what is typically expected for a given region or time of year.

In contrast, climate change encompasses broader shifts in weather patterns over time, natural disasters often refer to the catastrophic consequences resulting from extreme weather, and seasonal variations involve the expected changes in weather and temperature that occur with the changing seasons. Each of these concepts is related but distinct from the definition of extreme weather.
