Sea Floor Spreading Model Activity Cut Out

Simple diagrams and easy to understand explanations of the processes are included.

Sea floor spreading model activity cut out.

The width and length of the base are not critical as long as they are at least 12 cm wide and 30 cm long. 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. Displaying top 8 worksheets found for activity seafloor spreading.

Please refer to the picture as you build this model. The center slit represents a mid ocean ridge 2. The base is best if made from poster board or card stock. Cut 3 slits each slightly more than 8 cm wide.

Activity of the month activity of the month june 2008 plate tectonics and contributions from scientific ocean drilling summary in this activity. Cut out the labels approximately 1 tall by 1 2 wide. This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century. The earth does not get bigger.

Such magnetic patterns led to recognition of the occurrence of sea floor spreading and they remain some of the strongest evidence for the theory of plate tectonics. Have students pick up materials needed for the activity. 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.

Some of the worksheets for this concept are sea floor spreading work sea floor spreading a model of seafloor spreading inside earth work magnetic reversals activity name date sea floor spreading l 1 2 3 5 4 ovr l lesson 3 seafloor profiling seafloor spreading and subduction. Seafloor spreading is the creation of new seafloor or new oceanic crust 5. Have students work in groups of four. They will also model sea floor spreading at a spreading center such as the mid atlantic ridge.

Seafloor spreading theory that oceanic crust forms along submarine mountain zones known collectively as the mid ocean ridge system and spreads out laterally away from them. Operations carried out far from land and kilometers underwater will likely require expensive technologies sure to cut into your profit margin. Print cut out and glue together a three dimensional paper model that illustrates sea floor spreading and subduction. Sea floor spreading happens at places where plates are moving away from each other and where the liquid rock from the asthenosphere can come up to the lithosphere.

Today we are going to create a model that i hope will incorporate all of your important points 1. Students will make their own models of seafloor spreading and the magnetic strips that occur in the seafloor. A model of seafloor spreading key 1. To create a working model of sea floor spreading follow the model seen below figure 1.
