Mantle

Answer 3

below the crust 2500 Km thick
-Upper section is a solid called the lithosphere
-lower section is called the asthenosphere and is slowly flowing. which is made of many smaller (still huge) pieces

Question 4

lithosphere

Answer 4

Solid upper part of mantle made of many smaller (still huge) pieces

Question 5

asthenosphere

Answer 5

lower layer of mantle and is flowing slowly

Question 6

The core

Answer 6

has to parts the outer layer of molten metal
and the inner core which is solid
-the intense heat causes the asthenosphere to move and heat up and cool

Panthalassa

Answer 7

the super ocean to compliment Pangea

Question 8

niche partitioning

Answer 8

sharing the resources to increase carrying capacity and have co habitation
-seen with dipodicus and casmarasaurs. diplodocus went high and leafy, casmarasaurs was smaller and ate more diversely.
