Summary:
We dug a bit further into Unit 6 today (pun mostly intended) in discussing what’s happening inside Earth. Students went through a PowerPoint, which is posted below, that started off with a story of the deepest hole ever dug. The presentation covered the layers of the Earth, the composition of those layers, how convection currents form within the mantle, and what the effects of those currents can be. Of course this includes continental drift, the formation of mountains, and more dangerous effects like volcanoes and earthquakes.
