Chp 2: Types of Plate Boundaries

What are the 3 types of plate boundaries?

1. Convergent boundary 2. divergent boundary 3. transform boundary

There are 3 types of convergent plate boundaries

1. Oceanic - oceanic convergence 2. oceanic - continental convergence 3. continental - continental convergence

Tectonic Plates can move what 3 ways?

1. Toward each other 2. move away from each other 3. slide past each other

these mountains are formed by oceanic- continental convergence

Andes mountains

This trench is formed by an oceanic-oceanic convergence

Mariana trench

What is one of the most well known transform boundaries?

San Andreas Fault

T/ F: Transform boundaries are often found between two convergent, two divergent, or a convergent and divergent boundary?

True

True/False: The type of movement that occurs at the boundary between tectonic plates determines the type of plate boundary that exists between them?

True

A transform boundary is also called a ________ _______ boundary because crust is neither _____ nor _________ at this boundary (crust is conserved)

conservative plate/ created nor destroyed

A divergent boundary is also called a ___________ boundary because ____ crust or lithosphere is _____ at the boundary

constructive/ new/ created

This occurs where tow continental plates converge. Once plate subducts, melts and becomes part of the mantle. A mountain range forms in the other plate where crust is "squashed" together

continental- continental convergence

2 tectonic plates move towards each other at a ____ boundary

convergent

A convergent boundary is also called a _________ _________ boundary because one plate is slowly destroyed at the _______

destructive plate / boundary

2 tectonic plates move away from each other at a _____ boundary

divergent

these mountains are formed by continental- continental convergence

Himalayan mountains

The subducted plate ______ and becomes part of the ______

melts/ mantle

As the plate moves apart, ___ ____ from within Earth moves _____ and fills the space between the plates. The ____ ____ cools and forms new ______.

molten rock/ upward/ molten rock/ crust

Often mountains or volcanoes from on the continental plate near the boundary

oceanic - continental convergence

Often underwater volcanoes form near the boundary in the other plates

oceanic convergence

This occurs where 2 plates made of oceanic crust converge. Once plate subducts under the other, forming a trench. The subducted plate melts and becomes part of the mantle

oceanic convergence

This occurs where an oceanic plate converges with a continental plate. The oceanic plate subducts under the continental plate because its denser. A trench forms at the boundary

oceanic- continental convergence

2 tectonic plates slide past each other at a _____ boundary

transform

T/F: At a convergent boundary the denser plate subducts or moves below the less dense plate
