What do the two stripes in the activity represent in seafloor spreading model?
The stripes sported in the paper clearly represent the rock with both normal and reverse polarities. The activity with the title “split and separate” aims to discuss further the occurrence under the ocean particularly at the Mid-Atlantic Ridge.
What happens to the seafloor as you continue to pull on the strips?
The continual process of seafloor spreading separated the stripes in an orderly pattern. Oceanic crust slowly moves away from mid-ocean ridges and sites of seafloor spreading. As it moves, it becomes cooler, more dense, and more thick.
What is being modeled by pushing the strips up through the base?
What are you modeling by pushing the strips up through the base? The moving of new material from the athenoshpere through the crack litmosphere.
What do side slits represent?
The side slits stand for where subduction has occurred and the ocean floor has sunk in. Also, the space under the paper stands for the oceanic crust of the Earth.
What do the stripes in the two strips of paper represent?
The stripes on the strips stand for the magnetic stripes located on the ocean floor, which indicates the reversal of the Earth’s poles. The stripes need to be identical on both sides of the strip because they represent stripes of a magnetic field which has a repetitive pattern.
How does the spreading of the sea floor work?
Describe the process of Sea-Floor Spreading. In sea-floor spreading, the sea floor spreads apart along both sides of a Mid-Ocean Ridge as the new material is added. The older ocean floor moves away from the Ridge, like a conveyor belts, carrying the continents along with them.
Is the seafloor spreading along the Mid Atlantic Ridge?
Seafloor spreading is continuing today along Mid-Ocean Ridges such as the Mid-Atlantic Ridge. Predict what effect this will have on the size of the ocean basin: What is the name of the landmass through which the Mid-Ocean Ridge in the Atlantic Ocean passes?
How are magnetic stripes defend the idea of sea-floor spreading?
These rock show eruptions occur again and again. How do magnetic stripes defend the idea of Sea-Floor Spreading? The magnetic stripes are a symmetrical pattern found on either side of the Mid- Ocean Ridge, that contain the record of the reversal in the Earth’s magnetic field.
