The attracting and repelling forces of magnets are used in countless objects, from refrigerator doors to maglev trains. Refrigerator doors use the attraction of magnets to stay closed, while maglev trains use magnetic repulsion to hover
above rails. The center magnet in the picture is hovering between two magnets, making it appear to float. Which best
explains how the center magnet is able to hover between two other magnets?

the magnets can hover because like poles repel each other, causing the magnet in the center to float. so you have a South Pole of the top magnet facing down to the South pole of the middle magnet and the bottom would have to be North on top and south on the bottom.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
