Question

approximately how many total tectonic plates (major and minor) are there on earth?○ 3○ 15○ 40how do we measure the rate of plate movement? ○ survey it○ tape measure○ gps satellites○ we cant.which of earths physical layers can be compared to ooblick? ○ lithosphere○ asthenosphere○ inner core○ outer core

Explanation:

1. For the tectonic plate count: There are 7-8 major plates and around 30+ minor plates, totaling roughly 40.
2. For plate movement measurement: GPS satellites use precise positioning data to track slow tectonic plate motion over time; other methods are not feasible for this task.
3. For the oobleck comparison: Oobleck is a non-Newtonian fluid that acts solid under stress and flows otherwise, matching the asthenosphere's plastic, slowly flowing behavior under pressure.

Answer:

1. 40
2. GPS satellites
3. asthenosphere
