a. the combination of temperature inversions (because of being surrounded by mountains) and extended periods of sunlight result in the buildup of smog in los angeles.
b. there are no winds in los angeles. increased electromagnetic radiation because of los angeles’s low altitude.

Explanation:

Smog is dangerous air pollution. In Los Angeles, the first real smog was experienced in which the smog was extreme, and people taught it was an attack from the Japanese. However, that was not the case up to 1975 when America was required.

The frustrating years of scientific research led to denials and political protest as well as unwavering automobile Smog is, however, severe when it occurs far away from sources of pollution.

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
