Question 1

what materials are abundant in the crust?

Answer 1

oxygen and silicon

Question 2

what does the mantle contain?

Answer 2

oxygen and silicon

Question 3

what metals make up most of the earth’s core?

Answer 3

90% iron and 10% nickel

Question 4

what are the five physical layers of the earth?

Answer 4

lithosphere, asthenosphere, mesosphere, outer core, and inner core (respectively)

Question 5

outermost physical layer of the earth • physically cool and solid • made up of the crust and small part of the mantle

Answer 5

lithosphere

Question 6

physically hot and semiliquid • often having plasticity • made of the thin part of the upper mantle • responsible of the movement of plates in the lithosphere

Answer 6

asthenosphere

Question 7

rest of the mantle • hot and solid

Answer 7

mesosphere

Question 8

physically hot and liquid • determined by the direction a compass points

Answer 8

outer core

Question 9

physically is extremely hot and solid • pressure from the other layers makes it solid

Answer 9

inner core

Question 10

what is the term for semi-liquid condition?

Answer 10

plasticity

Question 11

why is the outer core liquid, since it’s one of the deeper locations of the earth?

Answer 11

because of it’s location, the extremely hot temperature making it liquid

Question 12

innermost layer of the earth • located at the hottest part, the earth’s interior • stays solid because of the intense amount of pressure on top of the layer

Answer 12

inner core
