Scientists have noticed 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, sea floor rocks found at the trenches are usually older than the sea floor rocks on at the mechanic bridges. which explanation of the past movement of earth's plates is best supported by this information? A. The continents were separated when new crust was formed at the edges of the continents pushed older crust towards the center of the ocean.

B. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges.

C. The formation of new crust at the trenches widened the seafloor and pushed the edges of the continents away from one another.

D. The Earth's crust formed at the trenches and moved towards the volcanic ridges to make room for newer crust, pushing the continents apart.​
