The earth does not get bigger.

Picture of a blank sea floor spreading model activity cut out.

Seabed contains several hundred years worth of cobalt and nickel. This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading. The strips of paper represent oceanic crust or seafloor. Students will make a paper model illustrating the concept of sea floor spreading and the development of symmetrical magnetic stripes on either side of a mid ocean spreading center.

Sea floor spreading edhelper images e993 com. Cut two strips of paper the same width as the slit and about a foot long each. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle. They will also model sea floor spreading at a spreading center such as the mid atlantic ridge.

Plate tectonics and the ocean floor. In recent years satellite images show a very clear mapping of the seabed and are used extensively in the study and exploration of the ocean floor. A demonstration of seafloor spreading created by me is included. Lab activity sea floor spreading.

A model of seafloor spreading key 1. The oldest sections should be the sections on both sides furthest from the middle 4. Please refer to the picture as you build this model. Activity of the month activity of the month june 2008 plate tectonics and contributions from scientific ocean drilling summary in this activity.

The 4 tactile surfaces will represent rock of various ages depending on how long ago it was laid down. This report describes how to build a model of the outer 300 km 180 miles of the earth that can be used to develop a better understanding of the principal features of plate tectonics including sea floor spreading the pattern of magnetic stripes frozen into the sea floor transform faulting thrust faulting subduction and volcanism. Model of sea floor spreading observing plate motions and model of sea floor spreading sea floor spreading project answer key lab 4 read modern interiors living room. Students will use actual data from historic oceanographic cruises to examine sea floor spreading.

Seafloor spreading is the creation of new seafloor or new oceanic crust 5. Using a shoebox or a small box cut a slit on the bottom down the middle about 3 inches long. Students work as individuals. The process that continually adds new material to the ocean floor is seafloor spreading and the continental slope.

As magma starts to harden into rock iron rich minerals solidify first. Their crystals are pulled into alignment by the earth s magnetic field just like a compass needle is pulled towards magnetic north. Most basalt magmas contain abundant molten iron. The center slit represents a mid ocean ridge 2.
