Study the geologic time scale. A geologice time scale. 4,600 M Y A to 544 M Y A, Precambrian Time. 544 M Y A to 250 M Y A, Paleozoic Era. 250 M Y A to 65 M Y A, Mesozoic Era. 65 M Y A to Today, Cenozoic Era. The Eocene period exists in Earth's history around 34 MYA. What could a scientist do to determine what era the Eocene period belongs to on the geologic time scale? Learn what happened during Precambrian time study information related to the Cenozoic era view the timing of events in the Mesozoic era research events that happened during the Paleozoic era

The correct answer is B. Study information related to the Cenozoic era

Explanation:

The purpose of a geologic time scale is to organize chronologically events of Earth's History, by diving time into eras, periods, ages, etc. In the case of the Eocene period, this occurred 34 million years ago; therefore, this period belongs to the Cenozoic era that covers events that occurred 65 Million Years Ago to Today as it is shown in the geological time scale.

In this context, to determine the era the Eocene belongs to it is important to study information related to the Cenozoic era especially the period of time this covers because through this you cannot know the Eocene belongs to the Cenozoic.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
