1.

The upper-most mantle, along with the overlying crust, behave as a strong, rigid layer, known as the (a)  

2.

Beneath the lithosphere lies a weaker region in the mantle known as the (a)   .

3.

The Earth’s lithosphere is broken into numerous segments called (a)   .

4.

Areas where two plates move apart, resulting in upwelling of mantle material, are called (a)   .

5.

The global (a)   is a track of elevated areas of the seafloor characterized by high heat flow and volcanism.

6.

Along the crest of some ridge segments is a deep canyonlike structure called a (a)   .

7.

(a)   is a mechanism that operates along the oceanic ridge system to create new seafloor.

8.

Tectonic forces sometimes pull the crust apart and the broken crustal fragments generate an elongated depression called a (a)   .

9.

Areas where two plates move together, resulting in one plate descending beneath another, are called (a)   .

10.

(a)   are sites at which lithosphere is being pulled back into the mantle. One plate slides and descends beneath another.

11.

(a)   are long, linear depressions in the seafloor located just offshore of either a continent or a chain of volcanic islands.

12.

At a depth of around 100 km, the mantle is sufficiently hot that the introduction of water with subduction leads to a process called (a)   .

13.

Mountains that are produced in part by volcanic activity associated with the subduction of oceanic plate beneath continental plates are called (a)   .

14.

Newly formed land consisting of an arc-shaped chain of small volcanic islands is called a (a)   .

15.

When plates slide horizontally past one another without the production or destruction of lithosphere is called the (a)   .

16.

Prominent linear breaks in the oceanic crust are known as (a)   .
