Follow the directions for the procedure here very carefully…it can be tricky!
17. Fill in the table below while following the procedure.
Name of Volcano
Necker Volcano
Distance from
the Big Island
of Hawaii
Age of the
Volcano
Distance Covered in One Year
[velocity (km/year) = distance ÷ time (cm/year)]
1,058 km ÷ 10,000,000 years = 0.0001058 km/year
Because 1 km = 1000 m
0.0001058 km/yr x 1,000 m/km = .1058 m/year
Because 1 m = 100 cm
.1058 m/yr x 100 cm/yr =
