Earth and Space Science: Origin and evolution of the earth system Grades 9-12, page 189 Interactions among the solid earth, the oceans, the atmosphere, and
organisms have resulted in the ongoing evolution of the earth system. We
can observe some changes such as earthquakes and volcanic eruptions on
a human time scale, but many processes such as mountain building and plate
movements take place over hundreds of millions of years.

Grades 6-8, page 73
Some changes in the earth's surface are abrupt (such as earthquakes
and volcanic eruptions) while other changes happen very slowly (such as
uplift and wearing down of mountains). The earth's surface is shaped in
part by the motion of water and wind over very long times, which act to
level mountain ranges.

Plants alter the earth's atmosphere by removing carbon dioxide from
it, using the carbon to make sugars and releasing oxygen. This process
is responsible for the oxygen content of the air.

The idea that the earth might be vastly older than most people believed
made little headway in science until the publication of Principles of Geology
by an English scientist, Charles Lyell, early in the 19th century. The
impact of Lyell's book was a result of both the wealth of observations
it contained on the patterns of rock layers in mountains and the locations
of various kinds of fossils, and of the careful logic he used in drawing
inferences from his data.
