Lithospheric plates

At ​ (a)   plate boundaries, plates collide with each other. ​ Where an ocean plate collides with the ​ (b)   plate, the

denser ​ (c)   plate, made of ​ (d)   material dives down ( subducts) into the mantle forming a ​ (e)   zone.

• convergent
• Continental
• ocean
• basaltic
• subduction

The ​lithospheric plates are various ​ (a)   , with some made only of ocean crust and others carrying continents on them.

3 kinds of plate motion are associated with plate boundaries, convergent, divergent, and transform.

The ​ (b)   forces at convergent boundaries, ​ (c)   forces at divergent boundaries, and ​ (d)   forces at transform boundaries result in a variety of surface features.

• sizes
• compressional
• tensional
• shearing

Match the following forces

• Transform

• Shearing forces

• Divergent

• Tensional forces

• Convergent

• compressional

At convergent plate boundaries, plates ​ (a)   with each other.

Where an ocean plate collides with a continental plate, the denser ​ (b)   plate, made of basaltic material, dives down ( ​subducts ) into the mantle forming a ​ (c)   zone.

Here an ocean trench forms on the surface and below ​ (d)   is consumed by the mantle.

The overriding Continental plate is ​ (e)   to form a chain of mountains like the Applachian mountains.

• collide
• ocean
• subduction
• old crust
• crumbled up

Where an ocean plate collides with a Continental plate, what occurs:

• denser oceanic plate subducts

  Continental plate rises and crumbles forming mountains

• Denser Continental plate subducts

  Oceanic plate rises and crumbles forming moutains

In areas where two ocean plates converge, the older, denser plate will subduct, also forming a trench on the surface, a long with a chain of islands called?

• Island arc

• Mountain range

• Marianna trench

If two Continental plates collide with each other the edges of both plates are crumpled up forming _________ mountains like the Himalayas of India.

• Tilted

• Folded

• Fault

An ​ (a)   is a curved chain of volcanic islands formed at a ​ (b)   plate boundary where one oceanic plate ​ (c)   (slides) beneath another oceanic plate, creating ​ (d)   that rises to form volcanoes

At divergent boundaries, the plates that move ​ (a)   and allow heat and ​ (b)   to flow up from below forming ​ (c)   ridges made of new crustal material.

When divergence occurs within a land mass, such as Africa, the tension results in the formation of a ​ (d)   which eventually develops into an ​ (e)   .

• apart
• magma
• parallel
• large rift valley
• arm of the sea

These plates move apart and allow heat and magma to flow up from below forming parallel ridges made of new crustal material, which created the Rift valley in Africa.

• divergent

• convergent

• subduction
