Nothing has been proven, but there are theories.
It is something that is proven as true and indisputable.
If something is not a fact, it means that it cannot be proven to be true based on evidence or logic. It may be an opinion, belief, or speculation.
The presence of large, rigid plates on the planet's surface that move and interact with each other, causing earthquakes and volcanic activity, is the best indication that the planet may have plate tectonics. Additionally, features like mountain ranges, deep ocean trenches, and mid-ocean ridges suggest the presence of plate tectonics.
i think that if anyone had to answer this, it would be someone with professional knowledge on the topic. I would probably say that someone like a PROFESSOR. Plate tectonics is a huge topic, and it needs constant thinking and deep thought into why each tectonic plate actually moves as it does. I personally think that the Atlantic Ocean is one that expands due to the fact that it simply is HUGE and vast as it is.
The related adjective is factual. It means pertaining to a fact, or true (actual).
In fact, Mars doesn't have plate tectonics like Earth.
An ancient ocean (Tethys Sea), opened to split Pangea in two.

Something capable of being proven
something that is proven to be true.
The fact that they were separated by sometimes thousands of miles suggested continental drift or plate tectonics.

It is something that is proven as true and indisputable.
In science, a theory is something that is not fully proven, but has strong supporting evidence. Some common theories that are well known, and seen by most people as fact include; Evolution, Plate Tectonics, and Gravity. All three of these have enough evidence to be scientifically sound, but we have not yet given 100% proof to turn them from scientific theory into scientific law.
To accept something as the truth means just that - to admit that something is a proven fact.
Something that can be proven true or false is already a fact. In science a hypothesis is something that might be proven true or false. In life, an opinion might be proved true or false and become a fact. Examples of facts are: The earth is round. The sun is hot. Water is necessary for life.
If something is not a fact, it means that it cannot be proven to be true based on evidence or logic. It may be an opinion, belief, or speculation.
