|'m studying plate boundaries and how volcanoes and earthquakes are formed/happen... i hav been asked to produce an interactive poster on constructive,destructive and conservative plate boundaries... has any one got any ideas or a websute would b great. thankyou (simple stuff only please.. nothin mega complicated)

I don'nt really know but would guess that constructive is where two plates push together with earthquakes and form new mountains, destructive is where the plates pull apart with or w/o e/quakes and allow volcanic eruptions and and con. are where nothing changes, with or w/o e/quakes.
I know what a poster is but not an interactive one (the only interactive things I know are people or computer programmes)
so can't help with that. Sorry.

Well, constructive plate boundaries are ones that are moving apart from each other, usually under the sea.
As the plates move apart, the lava comes up from underneath, creating new land.This is why it is called a constructive plate boundary. An example of this is the American plate and the African plate.
Destructive plate boundaries are ones that are moving towards each other. They can either create fold mountains, if they are two continental plates, or the heavier plate, an oceanic one, will sink below and lighter plate, a continental plate. This place is known as a subduction zone. As the oceanic plate sinks down and melts, the lava will push up under the continental plate and cause a volcano.
A conservative plate. You can remember this by John Major, who was a Conservative party leader. He always used to rub his hands back and forth, which is what the plates do. These are usually the sites of earthquakes. An example of a conservative plate boundary is the San Andreas Fault.
Good luck with the poster.

Not quite sure about your terminology, however -
Constructive/Divergent boundaries -- where new crust is generated as the plates pull away from each other.
Destructive/Convergent boundaries -- where crust is destroyed as one plate dives under another.
Conservative/Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
Plate boundary zones -- broad belts in which boundaries are not well defined and the effects of plate interaction are unclear.
The link is a good one, with clear diagrams and explanations.

check wikipedia, that might be a good source
