Question

A geographic information system (GIS) helps scientists visualize, analyze, and interpret data about locations on Earth. Which statement describes how GIS mapping can help in planning for floods? A) They can help identify weak infrastructure, like roads and bridges, that would need repair before a flood. B) They can help seismologists understand how floodwater can absorb into the ground and cause plates to shift. C) They can help meteorologists understand the air temperatures and cloud formations before and after a flood. D) They can help search for lost pets that were separated from their families during floods and other sever weather.

Answer 1

The correct answer is option A, that is, GIS can help identify weak infrastructure, like roads and bridges that would need repair before a flood.

Flood planning is utilized by mapping technicians in emergency management, public safety, planning agencies, or public works to assess the influence of seasonal flooding scenarios and establish the flood response plans.

In the process, the geographic information system can help in the assessment of flood risk and find the location of critical infrastructure. This can further help in the repairing of the infrastructures that are more susceptible to getting collapse due to massive flooding.

Answer 2

I would say that D is the most likely correct answer. A GIS can show the topography of an area, and an elevation map can show the likely route water would flow. If the houses the pets originated from are mapped, the route water would have taken as it flowed past each house can be mapped, providing a likely position the pets would have ended up at. Models of water flow based on topography can model water flow before a flood has happened, and can even investigate the effects of floods of different severities.
