Guide Question:
how does your match compared with Wegener's theory?

Arrange the process that describe the seafloor spreading by writing numbers 1-4 in the oval.
__ magma rises towards the mid ocean ridge.
__ subduction occurs on the other side of seafloor spreading where two oceanic plates or oceanic plate and continental plate collides.
__ seafloor spreads sideways away from the mid ocean ridge.
__ magma flows out of the mid ocean ridge, cools and becomes the new seafloor.

Evaluation
choices: seafloor, subduction zone, subduction. divergent, mid ocean ridge, mantle

Seafloor spreading is a geological process that occurs between two ovceanic plates at the 1) __________ plate boundary as magma moves towards the 2) ____________. At the other side of the site of seafloor spreading, when two oceanic plates or an oceanic plate and continental plate collide with one another, the less dense plate moves downward into the 4) ______________ through the process called 5) _______. The site where destruction of seafloor happens is called 6) ________________.
