transform boundry as in the san Andreas fault
continental drift and plate tectonics are two side of a coin. As the continents are interlinked with the plates; so as the plate moved due to conviction current the continents also tends to move causing continental drift. Moment of plates due to conviction current or due to the adjacent plate is called plate tectonics.
The spreading of plates from a divergent boundary that divides an existing landmass into two separate plates.
Your mother's family is your maternal family.Family history traced through the mother is called the matrilineal history.
Rivets are used to join metal plates by passing them through holes in both overlapped plates. The ends of the rivets are then hammered over, flattening the heads, which prevents them from pulling back through the hole.
the two plates are moving away from each other, and new crust is formed.
I believe it is called a fault, like the San Andreas fault in California.
Stegosaurus had 17 bony plates on its back. The plates were arranged in two rows, one one each side of the spine, and rather than the plates being directly across from each other, they alternated, with a plate on one side, then a plate on the other side, and then a plate on the first side again. In addition to plates, they had four bony spikes called thagomizers at the end of the tail.
Continental Plates
plates puled apart
If you are thinking of tectonic plates then there are more than two.
Two plates colliding and one being pushed upwards is called subduction.
The boarder between two plates is called a boundary.
Japan just two days ago. However there are two types of quakes. Plates running Side by side and plates running up an down
They are called a Plate Boundaries :)
when two plates converge it is called plate tectonics?
Two plates coming together is known as a convergent boundary.
It's called the Transform, that's the second stage of the plates.
