A deep ocean trench forms where the oceanic crust bends downward.

Sea floor spreading and subduction zones worksheet answers.

At deep ocean trenches subduction allows part of the ocean floor to sink back into the mantle over tens of millions of years. The processes of subduction and sea floor spreading can change the size and shape of the oceans. As magma flows out of the ridge the newly formed crust pushes older crust away from the ridge. The old crust gets pushed to the.

The two processes of seafloor spreading and subduction work together to constantly recycle and renew the earth s crust. By printing out this quiz and taking it with pen and paper creates for a good variation to only playing it online. Continue pulling the magma strips until the magma sticks slide across the ocean floor. Students should change the model so that magma is pushed out of the ridge not pulled.

While new earth is being born at mid ocean ridges by seafloor spreading in other areas earth is being destroyed at deep ocean trenches by subduction. The answer is that the ocean floor generally does not just keep spreading. As the ocean seafloor spreads the newly formed floor will adapt a specific magnetic signature according to the earth s magnetic pole at that time. Subduction happens where tectonic plates crash into each other instead of spreading apart.

The denser lithospheric material then melts back into the earth s mantle. Review answers to the seafloor structure handout by filling in the diagrams on board or using smartboard. This creates new ocean crust. Then answer the questions below.

Seafloor spreading is happening at b. Seafloor spreading is just one part of plate tectonics. At subduction zones the edge of the denser plate subducts or slides beneath the less dense one. This is a free printable worksheet in pdf format and holds a printable version of the quiz seafloor spreading and subduction.

Where there are deep ocean trenches subduction takes place. Refer back to the demonstration that you performed during the engage portion of the lesson to demonstrate this. You may use your book and whatever notes you have. Seafloor spreading explore 1 subduction in trenches 1.

Directions the diagram on the reverse side depicts an area of the ocean floor where different plates are shifting due to plate tectonics. As years pass lateral segments of seafloor will thus share the same signature on either side of the mid oceanic ridge. Begin by labeling the parts draw an arrow to indicate which feature you mean. Subduction is the process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle.
