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.
