Extreme temperatures refer to conditions that are significantly higher or lower than the average temperature for a specific region. These temperatures can be dangerous, leading to health risks such as heatstroke in high heat or hypothermia in extreme cold. They can also impact the environment, affecting ecosystems and wildlife. Regions experiencing extreme temperatures often face challenges such as droughts or heavy snowfall. For example, the Arctic experiences extreme cold, while desert areas can reach scorching highs. Understanding these conditions is crucial for preparing for their effects on human activities and natural systems.
