What does the center of the slit in the seafloor?

What does the center of the slit in the seafloor?

The center slit represents a Mid-Ocean Ridge 2. The strips of paper represent oceanic crust or seafloor. Seafloor spreading is the creation of new seafloor or new oceanic crust 5.

Why is it important that your model have an identical pattern of stripes on both sides of the center slit?

Why is it important that your model have an identical pattern of strips on both sides of the center slit? The model has identical strips because, as the magma rises at the mid ocean ridge ½ goes to the right and ½ goes to the left of the mid ocean ridge. Each one of these strips represents Earth’s magnetic history.

How do differences in density and temperature provide some of the force needed to cause sea floor spreading and subduction?

The cooler denser mantle sinks causing subduction and the hotter mantle rises to the surface causing sea floor spreading.

Are mid ocean ridges?

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. Two well-studied mid-ocean ridges within the global system are the Mid-Atlantic Ridge and the East Pacific Rise.

What do side slits stand for?

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 slits stand for what does the space under the paper stand for?

The side slits stand for old crust sinking back into the mantle of the Earth. The space under the paper stands for the stands for the mantle itself.

Where is the seafloor spreading the fastest?

East Pacific Rise
Some of our recent research involves hydrothermal and structural investigations along Earth’s fastest seafloor spreading center, the 28°S–32°S East Pacific Rise. The fastest present-day seafloor spreading, ~150 km/Myr, occurs along the Pacific-Nazca boundary between the Easter and Juan Fernandez microplates.

What do the side slits stand for what does the space under the paper stand for?

The center slit stands for the passage where the molten material can enter the Mid-Ocean Ridge, formed by the converging of plates. 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.

Why are mid-ocean ridges important?

Mid-ocean ridges are geologically important because they occur along the kind of plate boundary where new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a “spreading center” or a “divergent plate boundary.” The plates spread apart at rates of 1 cm to 20 cm per year.

What feature of the ocean floor does the center slit stand for quizlet?

What feature on the ocean floor does the center slit stand for? central valley of mid-ocean ridge where molten material is upwelling from below.

Which is more intense the central or sides of a single slit?

A graph of single slit diffraction intensity showing the central maximum to be wider and much more intense than those to the sides. In fact the central maximum is six times higher than shown here. At the larger angle shown in Figure 2c, the path lengths differ by 3λ/2 for rays from the top and bottom of the slit.

How is a single slit different from a double slit?

Light passing through a single slit forms a diffraction pattern somewhat different from those formed by double slits or diffraction gratings. Figure 1 shows a single slit diffraction pattern.

How is the angle between the slits and the screen the same?

If the screen is a large distance away compared with the distance between the slits, then the angle θ between the path and a line from the slits to the screen (see the figure) is nearly the same for each path.

How are slits separated in two slit diffraction?

Two-Slit Diffraction Suppose that in Young’s experiment, slits of width 0.020 mm are separated by 0.20 mm. If the slits are illuminated by monochromatic light of wavelength 500 nm, how many bright fringes are observed in the central peak of the diffraction pattern? Solution From (Figure), the angular position of the first diffraction minimum is
