Answer: The correct answer is:
1: All of Downtown is within Zone C and is relatively safe from flooding.
2: The HazardCity railroad on the south side of the river lies in Zone B and is only in danger of floods larger than the 100-year flood event.
Explanation:
Floods are caused by excess water, invading areas that are normally dry.
This phenomenon plays an important role in the regulation of water systems, for this reason, when these systems are modified or areas susceptible to flooding are affected, affectations can be generated.
The settlement of homes in areas of Ronda and, of environmental management and preservation of water bodies, increases the vulnerability to flood events, since such homes can be affected by the increase in the level of water bodies , in the same way they can affect the margins of the rivers and creeks by the realization of uncontrolled excavations for the foundation of the houses and by the constant traffic of all types of vehicles.
Because nitrogen oxides are created in the process of burning coal and other fossil fuels, some power plants are changing the way they burn coal. A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power.
Where slopes are steep, contour lines are closely spaced.
The slope is determined by the distance between contour lines; the greater the distance, the softer the slope.
<h3>What is contour line?</h3>
- A contour line of a two-variable function is a curve that connects points of equal value and along which the function has a constant value.
- It is a portion of the plane in the three-dimensional graph of the function f.
- On a map, you'll notice three different types of contour lines: supplemental, index, and intermediate. The thickest contour lines are called index lines, and they are typically numbered at some point along their length.
- There are numerous types of landforms on the surface of the earth, and they range greatly in height and elevation.
- The elevations of these surface features are depicted on contour maps, allowing you to view a two-dimensional map and imagine the Earth in three dimensions.
