Q

What is Thermal energy?

A

Energy in a substance that gives it its temperature

17
Q

What causes heat

A

The movement of atoms in the substance

18
Q

I Thermal energy a natural energy source

A

yep

19
Q

Where does most thermal energy come from?

A

The earth’s core

20
Q

How does the earth’s core get so hot

A

THrough the nuclear decay of atoms

21
Q

What is the energy gained from the earth’s thermal energy called

A

Geothermic energy

22
Q

How is fusion different from fission

A

Fusion is the fusing of atoms while fission is the splitting of atoms

23
Q

How does fission work?

A

Via the shooting of a rogue neutron at an atom’s nucleus and playing the most dangerous game of bowling ever where the nucleus is torn apart releasing energy and sending “fission fragments” everywhere which creates a chain reaction between the other bazzilion atoms which do the exact same thing.

24
Q

What is a major drawback of nuclear power

A

THe waste is highly toxic and there is a small chance of an accident that could effect the whole dang world
