Question

Application of plate tectonic theory in explaining orogenesis

Answer 1

A convergent plate boundary occurs when two plates push against each other. When the plates collide the less dense plate overrides the denser plate, this is called subduction. The crust on the plate that is pushed under is subjected to the high temperatures of the mantle below and the crust melts.

Answer 2

The Theory of Plate Tectonics is explored through the use of the Landform kit from the Utah Geological Survey. Students visualize the plates covering our earth by studying a map called the Dynamic Planet. This map illustrates that earthquakes, volcanoes, and mountain building occurs predominantly at plate boundaries. By learning about the three types of plate boundaries, students model the four types of mountain building.
