Answer: 2
Explanation:
Each line represents an increase in height of 1000ft.
And the volcano peaks are the circles with no other concentric lines inside (meaning that does not grow anymore, so it is the peak).
We can see that the peak of the top volcano has 13 lines, so it is around 13,000 ft high.
The bottom volcano has also 13 lines, so it is also around 13,000 ft high, then in the image we can see two volcanos higher than 7000ft.
