Think about the fact that water is most dense at 4°c, and the fact that ice is much less dense than water. a. what would happen to a lake or a pond in the winter (in a cold climate) if this wasn’t the case?

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 !
