In my opinion, <u>natural gas</u> is a source that will be most common in the future. Considering that natural gas is a fossil fuel that is used as a source of energy for heating, cooking, and electricity generation. It is also used in stoves, ovens, clothes dryers, lighting fixtures and other appliances that are used and needed in everyday life. Imagine a life without natural gas. We wouldn't be able to heat our homes, cook our food, etc.

The object's mass. Weight would be how gravity affected it, size is how large it is, density is how tightly the molecules are to each other. Mass is how much matter is in the object.
"Photosynthesis", this means plants breath in carbon dioxide and breath out Oxygen
