What is the pattern seen in the magnetic stripes on the seafloor?
A polarity reversal means that the magnetic North flips to where we know the South Pole is. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. These patterns of stripes provide the history of seafloor spreading.
What causes the strange stripes on the seafloor?
When scientists plotted the points of normal and reversed polarity on a seafloor map they made an astonishing discovery: the normal and reversed magnetic polarity of seafloor basalts creates a pattern. Stripes of normal polarity and reversed polarity alternate across the ocean bottom.
What part of the ocean does the center slit represent?
Mid-Ocean Ridge 2
What process happens at the two side slits?
Side slits are the resultant of subduction, a geological process wherein a tectonic plate moves under another plate. A side slit is basically the place where the process of subduction occurred. In addition, the subducting plate is the one that goes under the other plate, which is called the overriding plate.
What geologic feature is formed at the two side slits?
trench
What does the middle slit represent what occurs in this region in split and separate?
The middle slit represent the mid-ocean ridge where the actual seafloor spreading occurs.
What does the middle slit represent what occurs in?
The middle slit represents an ocean ridge, and what is happening here is the creation of new ocean floor. Q24. The mid-ocean ridge is where the earth expels magma from the inside it which then causes the Lithosphere to move.
What was the middle slit represent what occurs in this region?
When it comes to the middle-slit, this region actually represents the ridge of the mid-ocean. As per what occurs in this regions, we find that the spreading of the seafloor is occurring in this region.
What do the stripes in the paper represent in the activity split and separate?
The middle slit represents an ocean ridge, and what is happening here is the creation of new ocean floor. Secondly, what do the stripes in the paper represent in the activity split and separate? The stripes sported in the paper clearly represent the rock with both normal and reverse polarities.
What do the lines on the paper represent?
The stripes on the paper represent magnetic oscillations from spreading ridges.
How does the new seafloor form at Mid-Ocean Ridge?
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
What is the role of the mid-ocean ridge in the movement of lithospheric plates?
The mid-ocean ridge represents an area where, in accordance with plate tectonic theory, lithospheric plates (also called tectonic plates) move apart and new crust is created by magma (molten rock) pushing up from the mantle . …
Why is the earth not getting bigger despite the fact that molten materials are gradually coming out from the mid-ocean ridge?
New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth’s surface. But the Earth isn’t getting any bigger. Deep below the Earth’s surface, subduction causes partial melting of both the ocean crust and mantle as they slide past one another.
