Question

1. at divergent boundaries, tectonic plates are moving ____ from each other. one result of huge masses of crust moving apart is __ spreading. this occurs when two plates made of oceanic crust pull apart. a crack in the ocean floor appears and then magma oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a __ __. the magma also spreads outward, forming __ ocean floor and ____ oceanic crust.

Explanation:

At divergent boundaries, tectonic plates move apart. Oceanic - crust spreading occurs when oceanic - crust plates pull apart. A mid - ocean ridge forms as magma fills the space. The magma creates new ocean floor and new oceanic crust.

Answer:

apart; oceanic - crust; mid - ocean ridge; new; new
