Seafloor spreading explains wegener’s hypothesis. The earth has a magnetic field, which is thought to arise Use the following websites to help you with the questions below. 2) what prominent feature of the ocean floor is missing from the model at this point? Thread the two strips through slit b of the larger sheet.
Convection currents carry heat from the lower. Mid ocean range, a mountain on the sea floor sometimes hidden under hundreds of meters of water. The diagram on the next page represents a section of the ocean floor in the north atlantic. Material cools, it forms a strip of solid rock in the center of the ridge.
The process by which the ocean floor sinks into the mantle is called subduction. Thread the two strips through slit b of the larger sheet. Then more molten rock that formed before, pushing it ocean floor.
Seafloor spreading explains wegener’s hypothesis. (10 minutes) magnetic stripes show that material has moved away from the ridge over time. Ask partners to practice working the model several times. You may also use your notes. Web the process that continually adds new material to the ocean floor is called sea floor spreading.
The correct answer for each question is indicated by a. Web using geomapapp, students examine the age of the seafloor crust, calculate the rate of seafloor spreading at different locations around the world, and compare the spreading rates within the context of plate tectonics. Thread the two strips through slit b of the larger sheet.
As A Result, The Ocean Floors Move Like Conveyor Belts, Carrying The Continents Along With Them.
The earth has a magnetic field, which is thought to arise Thread the two strips through slit b of the larger sheet. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Then more molten rock that formed before, pushing it ocean floor.
Sea Floor Spreading, Adds New Material To The Seafloor.
Tape together the orange ends of the strips with the colored sides facing each other. The diagram on the next page represents a section of the ocean floor in the north atlantic. Use the following websites to help you with the questions below. Web seafloor spreading is a geologic process in which tectonic plates —large slabs of earth's lithosphere —split apart from each other.
Web In This Activity, You Will Observe The Pattern And Learn To Calculate The Rate Of Sea Floor Spreading.
The process by which the ocean floor sinks into the mantle is called subduction. Worksheets are sea floor spreading work with k. 2) what prominent feature of the ocean floor is missing from the model at this point? Web using geomapapp, students examine the age of the seafloor crust, calculate the rate of seafloor spreading at different locations around the world, and compare the spreading rates within the context of plate tectonics.
Web The Process That Continually Adds New Material To The Ocean Floor Is Called Sea Floor Spreading.
Label the diagram using the vocabulary you learned in 3: 1) what feature of the ocean floor does the center slit represent? Describe the process shown occurring at b, and explain what results from this. Mantle convection is the slow, churning motion of earth’s mantle.
Ask students to fold and cut striped spreading pattern vertically and staple together. Complete the model following directions. Annotated teacher edition (microsoft word 987kb oct7 11) Tape together the orange ends of the strips with the colored sides facing each other. 2) what prominent feature of the ocean floor is missing from the model at this point?
