If put together, they would fit perfectly into one huge super continent like a puzzle.
this supercontinent is called PANGEA. it is the greek word for "all lands".

Well it wasn't so much climate as the fossils that have been found. Fossils have been found in Antarctica of plants that only occur in tropical climates so at one point it must have had a tropical climate. That is the most dramatic example but there are more subtle ones that led him to believe that the continents, at one point, must have been in different locations on the Earth and then moved to where they currently are.
Most people actually state that Darwin beat Wegener to the theory of continental drift as he mentioned in most of his studies about the continents drifting apart and fitting together.
Whether or not you write down an hypothesis, if you conduct an experiment, you naturally have a hypothesis since you are trying to find the answer to something and have some sort of expectations.
Yes. A hypothesis describes what we expect to happen in an experiment. If we do the experiment and something different happens, then our hypothesis is "falsified", or demonstrated to be false. In that case, we'll need to reconsider our hypothesis to determine how it was wrong. We can revise our hypothesis and then conduct a different experiment to test it. It's easy to demonstrate that a hypothesis is incorrect, but it is impossible to prove that it is true.

The theory that all present continents were once joined together in a supercontinent called Pangaea was proposed by Alfred Wegener in 1912. He suggested that over time, Pangaea broke apart into the continents we see today, a process known as continental drift.
the continents were once joined together in a single landmass

The theory is called continental drift, proposed by Alfred Wegener in the early 20th century. It suggests that at one point in Earth's history, all continents were connected into a single supercontinent called Pangaea. Over millions of years, the continents drifted apart to their current positions.
The continents used to all form the supercontinent of Pangea. The theory of continental drift explains how they separated and formed today.

The theory of Pangea. It has somthing to do the a shift in the techtonic plates that caused the landmasses to separate I do believe.
This idea is called the theory of continental drift, which suggests that all continents were once part of a single landmass called Pangaea that later split and drifted apart over millions of years.
