Picture Of A Blank Sea Floor Spreading Model Activity Cut Out

This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading.

Picture of a blank sea floor spreading model activity cut out. The earth does not get bigger. Seabed contains several hundred years worth of cobalt and nickel. The 4 tactile surfaces will represent rock of various ages depending on how long ago it was laid down. The strips of paper represent oceanic crust or seafloor.

Most basalt magmas contain abundant molten iron. 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. Activity of the month activity of the month june 2008 plate tectonics and contributions from scientific ocean drilling summary in this activity. Please refer to the picture as you build this model.

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. They will also model sea floor spreading at a spreading center such as the mid atlantic ridge. Cut two strips of paper the same width as the slit and about a foot long each.

Plate tectonics and the ocean floor. A model of sea floor spreading teacher s guide ellen p. As magma starts to harden into rock iron rich minerals solidify first. 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.

Sea floor spreading edhelper images e993 com. A demonstration of seafloor spreading created by me is included. Over time new. 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.

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. Students will use actual data from historic oceanographic cruises to examine sea floor spreading. The oldest sections should be the sections on both sides furthest from the middle 4. Lab activity sea floor spreading.

The center slit represents a mid ocean ridge 2. 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. Their crystals are pulled into alignment by the earth s magnetic field just like a compass needle is pulled towards magnetic north. The process that continually adds new material to the ocean floor is seafloor spreading and the continental slope.
