Continental-Continental Convergent Plate Boundary
Transcript of Continental-Continental Convergent Plate Boundary
By, Danielle Jack, Madeline Robles, and Victoria Afe
The continental crust is the layer of solid rock which forms the continents. It is thicker than oceanic crust, but less dense. It is part of the lithosphere, and it floats on top of the soft asthenosphere.
What is it ?
Asthenosphere-the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance
Lithosphere-the rigid outer part of the earth, consisting of the crust and upper mantle.
When two plates move away from each other.
When two plates move toward each other.
When plates move past each other.
Types of boundaries
A type of a collision
The Himalayan Mountain Range is an example of a continental-continental plate collision. It stretches east to west from Afghanistan through Pakistan to India into Nepal, Tibet through Bhutan and ending in Burma, Asia. It occurred when two plates moved toward each other and pushed each other upward.
There are 7 primary tectonic plates.
There are 8 secondary plates.
There are at least 80 plates on earth in all.
Plates are named after the landmass they hold.
Continental plate collisions can create mountains, volcanoes, and earthquakes. But, earthquakes only occur if the plates are moving past each other in different directions (on a transform boundary.)
The Himalayan mountain range formed as a result of the collision between the Indian Plate and Eurasian Plate.
