What are two examples of the size scale and the time scale in earth science that are at opposite ends of the spectrum?

Opposite size scales

In Crystallography,a field related to both Chemistry and Geology, the size scales are often microscopic, while in Cosmology, the size scales are often measure in light years.

Opposite time scales

In Meteorology, the time scales are short because weather is very dynamic and varies from day to day and hour to hour. In Geology, times scales are often in the millions of even billions of years. There are rocks in the planet Earth that are over 4 billion years old, almost as old as the planet itself.

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
