The seafloor spreads at a rate of aproximatly 10 cm per year. if you were to collect data on the spread of the seafloor each week, which unit whoul you use to record your data. explain?

2,000 micrometers

Step-by-step explanation:

Well 10 cm in 50 or so weeks is 0.2 cm per week so you could use mm  

Then the measuremet would be about 2 mm per week.  

If the measurement is extremely accurate you could consider using micrometres.  

There are 1000 micrmetres in 1mm so in 1 week 2,000 micrometres
