Which dating technique would yield a result that might read 2.25 million years before present, plus or minus 50,000 years

Potassium argon dating

Explanation:

Potassium argon dating is a method used in determining the origin of a rock. I is done by comparing the ratio of radioactive argon to radioactive potassium in the rock. This method is used to date rocks that are thousands of million years old.

the assumptions made when using the Potassium argon dating include :

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.
