What is tectonic plate |
Earth surface is composed of tectonic plate which is constantly moving |
|
|
Tectonic plate divided into |
Continental oceanic plate |
|
|
The plate move at a rate of |
One to two inches per year This is due to convection currents |
|
|
What is the four motion of plate |
Collision Subduction Spreading Transform faulting |
|
|
What is collision |
Collision wherein two continental plates are moved toward each other |
|
|
What is subduction |
Subduction is when one plate subsides beneath the other plate |
|
|
What is spreading |
Spreading is which occurs when two plates are move away from each other |
|
|
What is transform faulting |
Transform faulting occur when two plates slide past each other |
|
|
What is the types of plate boundaries |
Convergent divergent transform |
|
|
Movements of plates leads to formation of |
Folds faults trenches volcanoes rift valleys and mountain ranges |
|
|
Boundary occurs when two plates collide. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust |
Convergent plate boundaries The denser plate is subducted underneth the less dense plate |
|
|
What are the three major type of convergent boundaries |
Ocean/continental Continental/ continental Oceanic/ oceanic |
|
|
Oceanic or continental |
When oceanic crust meets continental crust, the dancer oceanic plate is subducted, open forming a mountain range on the continent. Forming trenches volcanic mountains |
|
|
What is the example of continental or continental |
Continental or continental creates mountain ranges the most spectral example of this is the himalayas |
|
|
What is divergent plate boundaries |
Divergent plate boundaries occur when two plate moves away from each other This produce ridge , rifts , or rift valleys |
|
|
What is Transform plate boundaries |
Transform plate boundaries are where plates slide past each other. The relative motion is horizontal |
