This layer of nearly molten rock that lies beneath the Earth's crust is called the <u>mantle.</u><u />

The amount of LFG produced in a year from the calculations is 1.5768 * 10^8 cubic feet.
<h3>What is LFG? </h3>
The acronym LFG stands for land fill gas. It is a gas that is produced by the decomposition of biomass in a land fill. This gas can be burnt to generate steam. This steam is used to turn a turbine and generate electricity.
If 1 million tons of LFG is burnt in a day, then 365 million tons of LFG is burnt in one year.
1 million tons of waste produces 432,000 cubic feet of LFG
365 million tons of waste produces 365 million tons * 432,000 cubic feet /1 million tons
= 1.5768 * 10^8 cubic feet of LFG

We know that the poles had changed positions in the past, because of the arrangement of the crystals in the rocks made out of metal. The crystals of the metals act like the needle of the compass when the rock is cooling off and forming, they turn into the direction of the strongest magnetic field on the Earth, which is the North Pole. So by studying the rocks that are made out of metals and see the crystals arrangement and also estimate the age of the rocks, the scientist can precisely tell how has the North Pole been moving throughout time.
