After studying plate tectonics, Lee became interested in mid-ocean ridges and how rock develops as the tectonic plates spread apart, so he decided to investigate further. Which of the following statements are true about sea-floor spreading? Choose the three statements that apply. A. Young rock forms in layers on the ocean floor as spreading occurs. B. Magma flows through cracks in Earth's crust and hardens. C. Continental crust is formed by the ridges as they grow. D. Mid-ocean ridges are the sources of the spreading. E. Older rock is farther away from the mid-ocean ridges.

A, B, E

Explanation:

The magma rising through the cracks makes new younger rocks close to the crack as the magma follows out and hardens. This means that rocks farther away from the crack are older because they where formed when they where right next to the crack. They are father away meaning they got pushed back as time went on.

Mid ocean ridges are a result of the spreading not the cause.

Because they are in the middle of the ocean and they are moving constantly i dought the mid ocean ridges are creating continents.

wegner's theory did not explain how the continents could move
