Scientists have noted patterns in the Earth's seafloor structures. For example, volcanic ridges are typically located in the center of the oceans, and trenches are typically located along the edges of continents. In addition, seafloor rocks found at the trenches are usually older than seafloor rocks found at the volcanic ridges. Which explanation of the past movement of the Earth's plates is best supported by this information?
