Start with the "Important Terms and Concepts" to ensure you know the
terminology related to the topic of the chapter and concepts discussed.
Move on to the "Review Questions" to answer critical thinking
questions about concepts and processes discussed in the chapter. Finally,
test your overall understanding by taking the
"Self-assessment quiz".
"The
Chemistry of Earth" The World of Chemistry video
series (Annenberg/CPB) "Silicon, a cornerstone of the high-tech industry, is
one of the elements of the Earth highlighted in this program."
Additional information about Earth structure and mineral formation is
included. Go to the

"Intrusive
Igneous Rocks" Earth Revealed video series (Annenberg/CPB)
Most magma does not extrude onto Earth’s surface but cools slowly deep
inside Earth. This magma seeps into crevices in existing rock to form
intrusive igneous rocks. Experts provide a graphic illustration of this
process and explain the types and textures of rocks such as granite,
obsidian, and quartz. Once again, plate tectonics is shown to be
involved in the process.

"Metamorphic
Rocks" Earth Revealed video series (Annenberg/CPB)
"The weight of a mountain creates enough pressure
to recrystallize rock, thus creating metamorphic rocks. This program
outlines the recrystallization process and the types of rock it can
create — from claystone and slate to schist and garnet-bearing gneiss.
The relationship of metamorphic rock to plate tectonics is also
covered." Go to the

"Sedimentary
Rocks": The Key to Past Environments Earth
Revealed video series (Annenberg/CPB)
This program returns to the Grand Canyon: its exposed layers of
sedimentary rock allow scientists to peer into the geologic past. The
movement of sediment and its deposition are covered, and the processes
of lithification, compaction, and cementation that produce sedimentary
rocks are explained. Organic components of rock are also discussed. Go
