$400 Question from H 3 This layer is responsible for creating the magnetic fields around earth. Answer
$400 Answer from H 3 Outer Core
$500 Question from H 3 Why doesn’t the new plate formation at the mid-ocean ridges cause the surface of the earth to grow ever larger? Answer
$500 Answer from H 3 Plates are destroyed at subduction zones.
$100 Question from H 4 Where is the newest ocean crust located? Answer

$300 Answer from H 5 2 cm’s or 1 inch per year
$400 Question from H 5 Why do tectonic plates float on the asthenosphere? Answer
$400 Answer from H 5 Because the plates are less dense than the asthenosphere
