Seafloor Spreading Homework: 100M Yrs, 2K km Length, 1 cm/yr

AI Thread Summary
Seafloor spreading creates 1 centimeter of new crust annually over a 2,000 km length, resulting in significant surface area growth over 100 million years. The area can be calculated using the formula for area, which is width multiplied by length. To find the total area created, the annual crust growth must be multiplied by the total length and the number of years. Additionally, the fraction of Earth's surface that this new area represents should be calculated for context. Understanding these calculations is essential for completing the homework assignment effectively.

Homework Statement


Consider a seafloor spreading zone creating 1 centimeter of new crust over its entire 2,000 km length every year. How many square kilometers of surface will this create in 100 million years? What fraction of Earth's surface does this constitute?




Homework Equations





The Attempt at a Solution



Would I have to use a specific formula? Thank you.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
