Mexico city's most pressing environmental issue is

Air pollution is one of the most serious environmental issues in Mexico City, thanks to a combination of topography, meteorology and the huge concentration of pollution sources. The city sits in an elevated basin at an altitude of 2,240 m above sea level, hemmed in by mountain ridges to the east, south and west. This topography affects the city's climate in ways that contribute to the problem of air pollution. The basin often comes under the influence of high-pressure systems, with weak winds and persistent temperature inversions. The result is that pollutants are often trapped in the basin.

Most of the pollution comes from the burning of fossil fuels by almost 20 million residents, 3.5 million vehicles and 35,000 industries and services. Air pollution is generally worst in the winter, when rain is less common and temperature inversions are frequent.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.

i would think yes.

explanation:

because we have every natianlity in our country which makes us so diverse and unique. that's why in a lot of cities there are places like little italy, koreatown, chinatown.
