The answer is the outer core.
The outer core of the Earth is made up of liquid metal. The liquid in the outer core pass through the magnetic field and this causes the flow of electric current with in it. The magnetic field gets stronger as the liquid metal passes through it. What makes the liquid metal move is the inner core. It heats up the outer core which triggers convection.
The answer is B
the earth indeed does generate heat although it wouldnt nearly be enough to hold the amount of life that prospers on earth......A is just stupid same for C so B is your answer .... :) hope it helps
I think it’s a, hopefully you get it right!
Maybe not because after light increases stomas will decrease and after that plant leaf will take less co2 and less co2 mean less synthesis in the plant.
