B. Flood waters spread pollutants and diseases more rapidly.
C. Flood waters permanently damage crop soils.
D. Most cities are built in flood zones.
The correct answers are:
A. City buildings do not allow flood waters to recede;
The buildings in the cities are pretty much an obstacles for the flood waters, but they are also making it harder for the waters to recede because of that. This makes a real problem because big portions of the affected city can be under water for much longer period of time, thus more damage to be created, than if it was an open space.
B. Flood waters spread pollutants and diseases more rapidly;
The flood waters can take all sorts of things with them on their way, and very often they can bring in lots of pollutants of different sorts in the cities, and that can make an ecological disaster. Also, because of all the material with it, and creating high humidity, muddy, swampy environment for some time, usually in a period when it is pretty warm, lots of diseases can appear, and if they do, because of the terrible hygienic conditions it can cause quick spreading of them.

-which way is south from the map's compass
-examining the highest elevation on the map
-the direction of the points of the V shapes on contour lines
The correct answer is - the direction of the points of the V shapes on contour lines.
The contour lines can tell us a lot about the shape of the relief structures on the maps, and of the things that we can also see is the path of the rivers. When the rivers are running through a steeper part, practically their upstream, because they manage to cut and shape the relief structures around them, the contour lines take up a specific V shape. The points of the V are always on the river itself, and they point to the direction from where it is coming from, thus following the points of the V shape can bring us very easily to the upstream of the river.
-True
-False
Answer: True
Explanation: Scientists can identify where earthquakes will most likely occur because they know that earthquakes occur at plate boundaries they 3 kinds of plate boundaries are divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up. So scientists can identify where earthquakes will most likely occur.
