The goal is to review basic knowledge and skills that were learned during highschool. Please answer questions to the best of your abilities.We will provide some feedback on questions that seem to have caused the most trouble for all students taking the course. You will have two attempts. If - after the assignment is graded - you still have difficulty with any of the questions, re-visit the recommended resources. Your grade for this assignment will be the best score you achieve of all attempts. Results Displayed Feedback Question 1 Approximately how many years back in time did the Earth form? Response Feedback: Yes, good. And if you'd still like to brush up on concepts related to powers of ten and age of the Earth, seeTable 1.1 at https://opentextbc.ca/geology/chapter/1-6-geological-time/ or http://serc.carleton.edu/NAGTWorkshops/earlyearth/questions/age.html Question 2 The units for density are _____.

If you are still wanting to check your understanding of density, recall that it's defined as a ratio; amount of mass in a given volume. Density is mass (what units?) per volume (what units?). Write that down as a fraction (ratio). Now ask yourself: force more stuff into a fixed volume (box, bottle whatever), does density of the stuff go up down or stay same? Force same amount of stuff into a smaller volume - density up, down, same? Etc. Google the concept, or see http://funbasedlearning.com/lessons/density.htm Question 3 The Earth’s inner and outer core regions are known to be respectively: Response Feedback: Yes, good, however Earth's interior is a huge subject. Some basic can be learned from these three short resources are http://pubs.usgs.gov/gip/dynamic/inside.html http://pubs.usgs.gov/gip/interior/ http://www.livebinders.com/play/play?id=1873278 Question 4 The value 3.5 x 10 4 kilometers (also written as 3.5 x 10^4) without power-of-ten notation is [a] (write in the number only!). The value that is 2 orders of magnitude smaller is [b] (a number only), and the value that is twice as big is written using power-of-ten notation as [c] (a number written using power-of-ten notation).
