Hello, Henry here. I’ml looking for a special model of Earth. It needs to be as accurate as possible from the crust down to the core.
I would like to be able to make cross-sectional images of Earth under different tectonic plate configurations while being able to control the cross sections - how the cross section exposes the earth’s interior. I would like to have the cross sections adjustable by layer or some layers or all layers at once. The level of detail for the mantel and below the mantel can be low. Here is an example image (http://library.thinkquest.org/C0112871/Earth%20Layers_files/image008.gif) of the kind of cross section I wish to be able to produce, where the inner layers are mostly spherical, but the crust thickness stands out and is accurate. The model should have an image quality like this example image (http://www.kidcyber.com.au/IMAGES/earthXjup.jpg). Another option I would like is to be able to cut out entire sections, either square, conical, such as in this example (http://images2.wikia.nocookie.net/__cb20090316021204/astronomy/images/b/be/Earth-cutaway.img_assist_custom.jpg). I would like to be able to “pin” the cross section to the earth from where the cross section was taken out, or, as the earth is rotated, keep the cross section as is and have the cross section update as per the earth angle - writing past my bedtime, will go over in more detail to whomever takes this project on.
Above the mantel is where the detail will count the most. Use maps from online sources to make the crust thickness and plasticity as accurate as possible. For example, this image (http://igppweb.ucsd.edu/~gabi/crust/crust2a.thick.gif) can be used to make the overall crust thickness. I may have more that I can give, but will likely look for the ones I’d like you to use when the time comes.
This next part is for me to be able to study the tectonic motions, or experiment with various tectonic plate configurations. So the crust of the earth should be divided into sections as defined by the tectonic plate boundaries and the oceanic plates. I have to be able to manipulate these tectonic plates by being able to assemble them into the super continent “Pangea”, if I would so wish. I want the tectonic shields to be more rigid when adjusting them than the oceanic crusts on which they sit, but I also want the rigidity to be adjustable. Some maps for example use vertical exaggeration. I would like something similar in that I would like the tectonic shields and oceanic crusts to be “exaggeratable” in several ways, for the purpose of emphasizing their true movements and changes in shapes that will make the crust changes easier for me to see.
Next, when you look at the oceanic crusts, you can see how their seams give insight into their movements. I would like to be able to drag the tectonic shields and have the oceanic crusts being dragged with them by having the edge of the oceanic crust adjacent to the tectonic shield pinned to the tectonic shield. Or, I would like to be able to move the oceanic crust in sections almost independent of the tectonic shields, to be able to visualize the subduction of the oceanic crust underneath the tectonic plates and/or shields. The oceanic crusts and plates have to be as adjustable as possible for me to be able to configure them in multiple ways. The tectonic shields are to be adjustable such that, for example, if I tug on the west coast of north america, I would like that the rocky mountains get flattened, like stretching out a crumpled fabric. I would like to be able to do the reverse as well. By accounting for the crust’s thickness and plasticity, I would like to be able “push” on the southern tip of india, for example, and be able to have the crust crumple to produce the himalayan mountain range. Since india is a subcontinent, I would like it to be considered a separate tectonic plate in terms of manipulating its movements.
Lastly, each of the layer thicknesses are to be adjustable, either individually, or some, or all. But the crust is to have its curvature adjust to accommodate the changing radius of the earth. While we don’t see much space debris falling in the sky, the amount that does fall every year is substantial. Over the course of millions of years, that can be a significant amount of additional mass, which I would like to be able to account for in this model, however small that number may be. That can be simply a number calculated from the change in the earth’s radius and what that equates to in terms of mass added or taken away.
So, with the earth’s radius adjustable, I would like to see that as I’m changing only the innermost layers’ radii, that on the surface, the crusts are slowly almost drifting closer together, with the oceanic crusts getting “pushed” into the earth where their edges meet, or have them move independently of the tectonic shields. Their movements are to be governed by their relative thicknesses and plasticities.
There will likely be other details I’ve missed, but I hope this is enough information to be able to squeeze out a relatively accurate price for creating such a model, if you are up to the challenge. If you take this up, the model ought to be ready to be animated as a future project extension.
Hope this peaks your interest,
