Geology [jē-'ä-lə-jē]
The scientific study of the origin, history, and structure of the earth.

The earth's landscape is always changing, but the changes happen so slowly that they are difficult to see. Forces such as heat and pressure change the landscape through weathering and erosion. It can take thousands of years for rocks to change shape through erosion, and millions for one rock type to transform into another.
