say it is to see how the world was made." Sir Walter Scott (1771 - 1832)
It's the study of the Earth and its properties, behaviour, structure,
composition and geological history.
It addresses questions
* how the Earth was formed and how it continues to change;
* how to find the Earth's resources;
* how to predict its dangerous events.

Its more academic part
* the formation, evolution and composition of the planet Earth;
* the causes and nature of earthquakes, ice ages, volcanoes,
tsunamis and climate
and its more practical
* how to
find oil, gas, minerals and other resources including ground water;
* how to prevent problems like landslides, floods, sinkholes and water
* where to dispose nuclear waste.
