Tectonic Plates

Convergent Bounder

Play-doh Observation We saw that the clays were forming like mountains, and when they got higher, it folded and fell down.

Explanation A convergent boundary is when two plates collide with each other, and one land goes into ground and melts into the magma. When this happens on land, volcanoes and mountains form. When this happens in the sea, it makes new land, for example, Hawaii.

Analogy A convergent boundary is like a truck and a car crashing into each other, and the truck runs over the car.

Transform Plate Boundaries

A transform plate boundary is when two plates slide against each other in opposite directions. When it is a convergent plate, it destroys the crust. When it is a divergent plate, it makes new crust. But, Transform Plates are different. It will not destroy the crust and it will not make new crust. When it happens, it will cause earthquakes.

AnalogyWhen you rub your hands together, it will make heat and it will make energy.

This would be an example of a Divergent boundary (plate) Divergent Plates usually create rifts or rift valleys or something like that in Iceland (see figure A). Divergent is a long word used by scientists which means separating like the plates. When they pull apart the magma blasts up, dries and makes a new crust.

Play-Doh Plates! (see figure B) As we pulled away the plates they got softer in the middle.

Analogy Seafloor spreading is like a conveyor belt when it comes down from the ramp
