Today we began a discussion of the rock cycle: the transition from one rock type to another. We started by discussing the formation of sedimentary rocks from sand. This portion of the rock cycle includes processes such as weathering and erosion. We will continue the rock cycle grpahic organizer in class tomorrow.

For a great view of weathering and erosion, we watched a 30-second video clip advertisement for the Motorola PEBL phone. The video clip features the time-lapse weathering and erosion of a meteorite morphing into a smooth, soft ‘pebble’. If you missed class, Watch the video again via Google Videos by clicking play below or clicking here and check out the great representation of weathering and erosion!

Watch for erosion (movement of rocks, gravel, and sediment) as well as weathering (the breaking down of rocks into smaller pieces) as you watch the clip.

Tomorrow: Quiz over mineral characteristics - study the guided notes!
