Answer:
C, A, B, B
Step-by-step explanation:
Question 1: C. inner core
Why? Because the inner core is literally the center of the Earth. Meaning it is the hottest part of the Earth.
Question 2: A. crust
Why? The crust is the outer most layer which is the layer we walk on so to speak. The Earth can be broken up into four layers and as said before the crust is the outer part of it. It is actually amounts to less than 1% of Earth's volume.
Question 3: B. basalt
Why? If we were to average the oceanic crust we would get something around six kilometers and this is the thickness. This is mostly made up of basalt.
Question 4: B. outer core
Why? Due to difference in pressure and temperature the outer core tends to release dense matter which sinks while warm (less dense rises). This causes the Coriolis force, resulting from the Earth's rotations.
