A) The earth's mantle is the largest element of the earth, occupying 82 percent of the total volume and 65 percent of the total mass of the earth.
B) Most of the earth's mantle is in gaseous form.
C) This layer has the maximum density of all the layers.
D) Immediately above the mantle is the crust of the earth.
Correct Answer: A
Solution :[a] Most of the mantle of the earth is not in gaseous but in liquid form. The maximum density is not in the mantle layer but at the centre of the earth where it reaches about 11-12 while it varies from 3 to 5 in the mantle. The layer immediately above the mantle is the asthenosphere and not the crust.
