Geological Processes – Theater
There are four clips about three topics in today’s presentation. Go to www.marric.us/teaching,
webquests, Unit 2, and then look for the link named Geological Processes Theater. Before you begin
watching the clips preview the questions you will be answering so that you can focus during your
viewing. After you watch topic clips, write three summary sentences and the answers for the
questions that follow. After you have finished watching all the clips, then answer the quiz questions.

Onscreen Questions:
• What can rocks tell scientists about changes on Earth?
• What are the three main types of rocks?
• Describe how each type of rock is formed
1)
