Print Out Of A 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.

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

Spreading rates determine if the ridge is fast intermediate or slow. Operations carried out far from land and kilometers underwater will likely require expensive technologies sure to cut into your profit margin. If you were making a model of sea floor spreading what are the important ideas that are associated with seafloor spreading. Labels with the number 1 2 3 and 4.

Think pair share turn and talk to your elbow partner. Going to consider how we might make a model that would explain or demonstrate sea floor spreading. 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. Make similar labels in braille using braille label paper.

Attach the braille labels to the appropriate print labels. Cut 3 slits each slightly more than 8 cm 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. Activity of the month activity of the month june 2008 plate tectonics and contributions from scientific ocean drilling summary in this activity.

This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading. This choice is left up to the teacher depending on the reasoning skills of the students. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. A model of seafloor spreading purpose.

Alternatively this lesson can be taught after the concept of seafloor spreading so the evidence can be put into context. 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. 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.

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. Cut out the labels approximately 1 tall by 1 2 wide. Print 2 sets of 48 pt.

When taught in series the lessons proceed in much the same way that scientists discovered seafloor spreading and plate tectonics. Model of seafloor spreading templates one with three straight lines and another with striped bands or striped bands with arrows colored pencils or crayons.
