4. when will the next supercontinent form? examine the western coast of south america, the eastern coast of asia, and the pacific ocean. if south america and africa are separating and the atlantic ocean is growing, then the opposite must be occurring on the other side of the earth (the americas are getting closer to asia and the pacific ocean is shrinking). how far apart are north america and mainland asia in cm? (measure the distance across the pacific at 40 degrees north latitude- basically measure between northern california and north korea)? take that distance and divide it by the speed you calculated in question 3 to estimate when the next supercontinent will form. show your work!
