What is a boundary?
|
The area where two tectonic plates meet
|
|
|
What is a possible result of plates moving along a transform boundary?

|
|
|
What do tectonic plates consist of?
|
Both continental and oceanic crust.
|
|

|
|
|
What is the role of the asthenosphere in the movement of tectonic plates?
|
The asthenosphere is a layer made of solid rock that flows very slowly. The tectonic plates float, or move very slowly on top of the asthenosphere.
|
|
|
If the Earth's crust is growing at mid-ocean ridges, why doesn't the Earth grow larger?
|
Through sea floor spreading, the older lithosphere is pushed away from the mid-ocean ridge and over time is subducted at the subduction zone where the rock is recycled and begins the cycle all over again.

|
|
Why are the Appalachian Mountains now located in the middle of the North American plate?
|
The Appalachian Mountains were formed when The North American and African plate collided. Over time the plates separated and moved that the mountains were no longer at the plate boundary.
