Practice AP Environmental Science questions on impervious surfaces, flooding, urban sprawl, resource depletion, saltwater intrusion, and carbon emissions.
There is a natural climate phenomenon that occurs in the equatorial Pacific Ocean because of periodic fluctuations in sea surface conditions and atmospheric circulation. This phenomenon happens every few years, resulting in shifts in temperature and precipitation in many parts of the world.
Figure 1 shows temperature and precipitation patterns associated with one phase of this phenomenon in the equatorial Pacific Ocean. Figure 2 shows the associated temperature and precipitation patterns that occur over North America.

Respond to parts A, B, C, D, E, F, G, H, I, and J.
Increases in regional precipitation can lead to increased flooding in certain locations.
Describe one reason why there is an increased risk of flooding in urban areas during extended periods of precipitation.
