My apologies for the late post of videos on the Chapter 9. But as you prepare for your class test this Saturday, please go through the videos below if you still have any queries or aren't sure of some concepts.
Here's the video I showed you during class, when I wanted to introduce to you the three different rock types and the rock cycle. It's really a good visual re-cap of the whole chapter itself. You can watch the video until 1.24 minutes as after that it is not relevant, but more for general knowledge.
The next few videos are quite old videos but quite good in knowing in details the different rocks.
IGNEOUS ROCK
Here's a video that shows you how to identify igneous rocks..
SEDIMENTARY ROCK
Here's a video about the Grand Canyon and how it is made up of mainly sedimentary rock, for your interest. =)
METAMORPHIC ROCK
Finishing it off, is this rock cycle video I showed you in class, go through the animation and in your mind have the thought process of what the rock cycle is about.
This can be found at http://www.geolsoc.org.uk/gsl/site/GSL/lang/en/page3892.html too.
