Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the first of three Science Objects in the Earth’s Changing Surface SciPack. It explores the forces within Earth that cause continual changes on its surface. Heat flow from the decay of radioactive isotopes and the gravitational energy from Earth’s original formation produce movement of the tectonic plates, which cause earthquakes and volcanic eruptions and create mountains and ocean basins.
