what is meant by perspex plate?
111004
Perspex is the trade name for a clear, lightweight, tough plastic first produced in 1930. It is widely used for watch glasses, advertising signs, domestic baths, motorboat windscreens, aircraft canopies, and protective shields. \n\nSO perspex plate is a plate made of this material.

you can surely rule out some things based on the type of plate you are using.  assuming that you have covered that base, you can separately pick a colony that you think may be a contaminant and look for differences in growth patterns, color, morphology, gram stain, growth on other media, and if all else fails, you can sequence it to find out exactly what it is.

Acrylic distemper contain acrylates, a class of organic compounds which are used to make polymers such as perspex.\n\nSynthetic distempers include the acrylics.

A destructive plate boundry causes one plate to be subducked below another, (sucked under basically) this causes it to melt and then rise to the surface where it forms the Mount Pelee volcano\n\nHope that helps

polymethacrylate resin is the synthetic polymer of methyl methacrylate. This thermoplastic and transparent plastic is sold by the tradenames Plexiglas, Perspex, Acrylite, Acrylplast, and Lucite and is commonly called acrylic glass or simply acrylic.

It will pretty much look the same. Normal plate techtonics\nmoves continents very very slowly and you need more then a\nthousand year window to see any real difference. Just look\nat maps from the year 1006 if you don't believe me.

Was it really necessary to post this question here? You couldn't look it up using a web search tool?\n\nWikipedia lists the current major plates:\n\nAfrican Plate\nAntarctic Plate\nArabian Plate\nAustralian Plate\nCocos Plate\nEurasian Plate\nIndo-Australian Plate\nIndian Plate\nNazca Plate\nNorth American Plate\nPacific Plate\nPhilippine Plate\nScotia Plate\nSouth American Plate\n\nand also gives a map. You can look and decide what plates are major enough to be on your list of 7.

Like pauliegone said, the lithosphere does in a way seperate the crust from the mantle.  The tectonis plates (crust) are supported by this semisolid layer.  However, the lithosphere is considered, by some scientists, part of the mantle.  So, it depends on which scientists you believe, although I believe that pauliegone is correct.

Fractured crust is the collective term for tectonic plates.

Plate tectonics\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\n    \nBridge across the Álfagjá rift valley in southwest Iceland, the boundary of the Eurasian and North American continental tectonic plates.Plate tectonics (from Greek τέκτων, tektōn "builder" or "mason") is a theory of geology which was developed to explain the observed evidence for large scale motions within the Earth's crust. The theory encompassed and superseded the older theory of continental drift from the first half of the 20th century and the concept of sea floor spreading developed during the 1960s.\n\nThe outermost part of the Earth's interior is made up of two layers: above is the lithosphere, comprising the crust and the rigid uppermost part of the mantle. Below the lithosphere lies the asthenosphere, which is a more viscous zone of the mantle. Although solid, the asthenosphere has very low shear strength and can flow like a liquid on geological time scales. The deeper mantle below the asthenosphere is more rigid again.\n\nThe lithosphere essentially floats on the asthenosphere. The lithosphere has broken up into what are called tectonic plates—in the case of Earth, there are ten major and many minor plates. These plates move in relation to one another at one of three types of plate boundaries: convergent, divergent, and transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries. The lateral movement of the plates is typically at speeds of several centimetres per year.

Under the continents.  The term refers to the basaultic shields on which the continents "float" on the magma underneath.  When they shift and grind against one another, we have volcanoes and earthquakes.
