Print Out Of A Sea Floor Spreading Model Activity Cut Out

Attach the braille labels to the appropriate print labels.

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

Think pair share turn and talk to your elbow partner. The width and length of the base are not critical as long as they are at least 12 cm wide and 30 cm long. Print 2 sets of 48 pt. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.

This choice is left up to the teacher depending on the reasoning skills of the students. They will also model sea floor spreading at a spreading center such as the mid atlantic ridge. Activity of the month activity of the month june 2008 plate tectonics and contributions from scientific ocean drilling summary in this activity. Spreading rates determine if the ridge is fast intermediate or slow.

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. To create a working model of sea floor spreading follow the model seen below figure 1. The base is best if made from poster board or card stock.

Make similar labels in braille using braille label paper. Going to consider how we might make a model that would explain or demonstrate sea floor spreading. This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading. Cut 3 slits each slightly more than 8 cm wide.

Labels with the number 1 2 3 and 4. 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. Operations carried out far from land and kilometers underwater will likely require expensive technologies sure to cut into your profit margin. When taught in series the lessons proceed in much the same way that scientists discovered seafloor spreading and plate tectonics.

Students will use actual data from historic oceanographic cruises to examine sea floor spreading. 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. A model of seafloor spreading purpose. 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.

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. Cut out the labels approximately 1 tall by 1 2 wide.
