Which factor affects the range of temperature within both the Rocky Mountains and the Himalayan Mountains?

a. elevation
b. continentality
c. wind systems
d. ocean currents

a. elevation

Explanation:

Elevation is the factor that affects the range of temperature within both the Rocky Mountains and  the Himalayan Mountains because with elevation, temperature decreases on the mountain. at the foot of the mountain the temperature is warmer while on the top of the mountain, the temperature is colder and very low. So we can say that elevation is the prime factor the range of temperature on mountains.

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.
