Question

Define the term: average rainfall over 10 year period?

Answer 1

The average amount of rain that occurred during a ten year period....In a specific region. ( The total amount divided by ten)

Answer 2

its adding up the total rainfall in the past ten years and dividing it by 10

Answer 3

it adds the rainfall from each year and that total is divided by ten.  It will give you a good estimate of how much rain falls each year.  Some years will be more and some will be less, that's the reason you take an average

Answer 4

it means like the average amount of rain and the different measurements r taking within that 10 year period.

Answer 5

The total rainfall over the period divided by 10.  The answer will be in inches/year (English) or cm/year (metric).

The rainfall itself is a measure of volume per unit area.  Units cancel to leave a linear measure.  Basically 80 cm of rain means that if you caught all of the rain for the entire year in a cylinder with no evaporation, it would fill the cylinder to a depth of 80 cm.
