Which of the following is an example of a large spatial scale event?

Climate change is considered a large spatial scale event because it affects global patterns and processes over vast geographic areas and spans extended periods. Its impacts are not confined to a local area but are felt worldwide, influencing atmospheric conditions, sea levels, and ecosystems on a global scale. The phenomenon involves complex interactions among various systems and can lead to significant changes in weather patterns, biodiversity, and even human settlements across continents.

In contrast, urban development and reservoir construction, while impactful, typically focus on more localized areas. They may alter specific regions but do not inherently encompass the extensive, systemic changes associated with climate change. Soil erosion, though it can have significant local environmental effects, primarily occurs within individual landscapes and does not impact a global scale in the same manner as climate change does.
