The correct answer is A. Urban areas have higher temperatures.
Explanation
Urban Area is a term to refer to cities. Urban areas are characterized by having a developed infrastructure (wide roads, vehicular bridges, wide platforms, tall buildings, residential areas, industrial areas, among others).
Recent studies affirm that urban areas are warmer than surrounding areas; This phenomenon is because the materials with are built buildings, roads, houses, and others, concentrate the sun's rays, increasing the temperature of cities. In addition, the lack of trees deepens this phenomenon, because the trees contribute to cooling by physicochemical processes such as evapotranspiration.
According to the above, it is possible to affirm that urban areas are hotter than their surrounding area because they lack vegetation, and the materials with which it is built contribute to the increase in temperature.
On the other hand, urban areas are characterized by habitat fragmentation, more problems with soil erosion, and less rain infiltration into the soil.

<h3><u>Answer;</u></h3>
pH = 6.34
<h3><u>Explanation;</u></h3>
pH is given as -log{H+]
But;
pH + pOH = 14
However;
pOH = -log [OH-]
[OH-] = 2.20 × 10−8 M
Thus;
pOH = -log (2.20 × 10−8 M)
= 7.66
But;
pH = 14 - pOH
= 14 - 7.66
<u>= 6.34 </u>
The answer would be: Igneous Rocks
