Print Out Of A Sea Floor Spreading Model Activity Cut Out

Going to consider how we might make a model that would explain or demonstrate sea floor spreading.

Print out of a sea floor spreading model activity cut out.

When taught in series the lessons proceed in much the same way that scientists discovered seafloor spreading and plate tectonics. 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. Cut out the labels approximately 1 tall by 1 2 wide. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.

Make similar labels in braille using braille label paper. The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate. 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. A model of seafloor spreading purpose.

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. They will also model sea floor spreading at a spreading center such as the mid atlantic ridge. Attach the braille labels to the appropriate print labels. Students will use actual data from historic oceanographic cruises to examine sea floor spreading.

Cut 3 slits each slightly more than 8 cm wide. Operations carried out far from land and kilometers underwater will likely require expensive technologies sure to cut into your profit margin. The purpose of this activity is to make a simple model that shows the evolution of oceanic crust through sea floor spreading. To create a working model of sea floor spreading follow the model seen below figure 1.

This choice is left up to the teacher depending on the reasoning skills of the students. Activity of the month activity of the month june 2008 plate tectonics and contributions from scientific ocean drilling summary in this activity. Model of seafloor spreading templates one with three straight lines and another with striped bands or striped bands with arrows colored pencils or crayons. This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading.

If you were making a model of sea floor spreading what are the important ideas that are associated with seafloor spreading. 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. Alternatively this lesson can be taught after the concept of seafloor spreading so the evidence can be put into context. Spreading rates determine if the ridge is fast intermediate or slow.

Print 2 sets of 48 pt. The width and length of the base are not critical as long as they are at least 12 cm wide and 30 cm long.
