Answer:
Pacific Plate
Explanation:
These islands are volcanic arc formations due to the convergent boundary where the pacific plates subducts under these Indo-Australian plates, so the subducting pacific plate created the Kermadec ridge that runs from north island of New Zealand to Tonga northeast wards.

Answer: Doubling in size over equal time. 
Explanation: Population exponential growth can be said to be an increase in the number by multiplying together a number of equal factors, where the exponent specifies the number of factors to multiply. 
 For example, in 7² the factors are all 7, the power is 2 and the exponentiation gives 49. 
This example is indicative of doubling in size.
