5. Aside from the sun as Earth’s main source of heat energy, humans could theoretically survive without the sun’s heat as the planet’s inner core is hot enough to supply energy to its inhabitants. It is estimated that the core temperature is between 5,000 to 7,000 degrees Celsius. It is just as hot as the sun’s surface too!

6.97% of water on Earth can be found in the oceans, while only 3% of water can be found in fresh water reservoirs and fresh water supply.
