Read the explanation the ancient Greeks had for earthquakes.  Then read the explantion we use today.  Then compare the two.  

Students investigate how mountains are formed. Concepts include the composition and structure of the Earth's tectonic plates and tectonic plate boundaries, with an emphasis on plate convergence as it relates to mountain formation. Students learn that geotechnical engineers design technologies to measure movement of tectonic plates and mountain formation, as well as design to alter the mountain environment to create safe and dependable roadways and tunnels.

Using this resource, students will select one of the times from the list and travel through time and check out what the Earth looked liked in the far distant past or what it might look like far into the future. At each stop there is more information about each geological time period.
