Each year, new seafloor is added at the Mid-Atlantic Ridge. The Atlantic Ocean widens, causing North and South America to move farther away from Europe and Africa. Close to the ridge, rocks are young
Each year, new seafloor is added at the Mid-Atlantic Ridge. The Atlantic Ocean widens, causing North and South America to move farther away from Europe and Africa.
Close to the ridge, rocks are younger. As you move away from the ridge, the rocks become older. The rate of seafloor spreading has not been the same over time. In this activity, you will calculate the average rate of seafloor spreading and then determine when the seafloor started to spread.
1. Where would you find the oldest sections of seafloor, near the continents or near the Mid-Atlantic Ridge?
