Let’s calculate what would happen if an asteroid hit Corvallis… Question 1: Da (crater diameter) = ? km SU = 0.06Da1.1 SU (structural uplift of the crater’s center) = 446m To help you get started, here is how to calculate for Da. SU = 0.06Da1.1 .446km = (LNx) = X .06 X = ? (INV) (LNx) = Da km = ? km 1.1 Da km (Yx ) x 1.1 = 7.44 x .06 = .446km = 446m As you calculate the remaining questions, be mindful of units and converting from one type of unit to another.
