Question 6

what changes as you travel through earths layers?

Answer 6

temperature and pressure

Question 7

2 types of crust

Answer 7

oceanic

continental

Question 8

mantle 3 parts

Answer 8

lithosphere: solis
mesosphere: solid
asthenosphere: semi solid

Question 9

outer core

Answer 9

liquid

temps are too high enough to melt metals

Question 10

inner core

Answer 10

solid

pressure high so its solid

Question 11

how does a convection current happen?

Answer 11

material in the mantle near the outer core heats up, causing density to decrease. The less density martial rises. Mantel material near crust is cooler which makes it more dense and sink it the the asthenosphere.

Question 12

law conservation of matter

Answer 12

states that for any system closed to all transfers of matter and energy the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed.
