Science homework Advanced and Intermediate

Hi students,
You should have done by now sections 1, 2 and 3. If you haven't, please do so it will count for your next grade.
To answer these sections you must read from page 6 to 22.
We have started section 4 in class ( Sea-Floor Spreading) so by the end of next week you will have to answer the questions of section 4. Read page from 23 to 29 to answer section 4.
Due date Thursday 11th. 2007
Thank you
Ms. Yolanda Banuet
