Question 1

The crust, Earth’s relatively thin, rocky outer skin, is of two different types

Answer 1

continental and oceanic crust

Question 2

The ______ consists of the entire crust and uppermost mantle and forms Earth’s relatively cool, rigid outer shell

Answer 2

lithosphere

Question 3

In regions where trenches do not exist, the steep continental slope merges into a more gradual incline known as the _______

Answer 3

continental rise

Question 4

Between the continental margins and oceanic ridges lie the _______

Answer 4

deep-ocean basins

Question 5

where plates move apart, resulting in upwelling of material from the mantle to create new seafloor

Answer 5

Divergent boundaries

Question 6

where plates move together, resulting in the subduction (consumption) of oceanic litho- sphere into the mantle

Answer 6

convergent boundaries

Question 7

where plates grind past each other without the production or destruction of lithosphere

Answer 7

Transform fault boundaries

Question 8

This hot material slowly cools to become solid rock, producing new slivers of seafloor. This happens again and again over millions of years, adding thousands of square kilometers of new seafloor.

Answer 8

seafloor spreading

Question 9

Plate margins where oceanic crust is being consumed are called _______

Answer 9

subduction zones

Question 10

layer of the earth: Solid, composed of Iron and Nickel

Answer 10

inner core

Question 11

layer of the earth: liquid

Answer 11

outer core

Question 12

layer of the earth: Solid rock, formed of crystals interlocking. Can flow

Answer 12

Mantle
