How the Earth was Formed

We're studying geology using an Intellego unit study, which we are loving. Today, we watched a documentary on the formation of the earth, researched rocks and minerals in daily life, learned some new vocabulary (and reviewed others), and completed a brief writing project.  Here is a short writing project about the formation of Earth:

Short, sweet, simple, to the point, and WELL UNDERSTOOD. :)

Vocabulary introduced and/or reviewed:

continental crust
mantle
core
mass spectrometer
plate tectonics
rift
MOHO
tufa towers
xenoliths
subduction

Really loving Intellego. If you haven't heard of them, I encourage you to check them out. Great stuff.
