upper mantle make up the lithosphere. The lithosphere is divided into

individual sections called plates. The rest of the mantle makes up the

asthenosphere. Convection in asthenosphere causes the plates to shift and

move about. We can tell where the plates are or have been because

volcanoes and earthquakes have their own boundaries when the are active.

Tectonic plates have three relationships with each other. The have

convergent boundaries when they collide, divergent boundaries when they

move apart, and transform boundaries when they slide past each other. The

friction and heat caused by the plates sliding all over the place causes

volcanoes if it melts the rock and earthquakes if the plates slip while sliding

then we stuck the tacks through designated holes. With everything in tact

of gravity's what really moves the plates of the earth. The model doesn't

us understand the different plates and how they work. The model is a great

important to see all of the plates to fully understand the plate tectonic

The lab was to construct a model showing the different kinds of boundaries.
