<em>A scientist can contribute to the formation of a theory in a particular subject by conducting research along the line of that subject.</em>
Conducting research requires the formation of a hypothesis and testing the hypothesis by conducting a relevant experiment during which data are gathered, analyzed, and interpreted in order to falsify or accept the hypothesis.
A good experiment must be replicate-able. When the same experiment is repeated by different independent researchers and the same conclusion is arrived at, this could potentially lead to the formation of a theory.
<u>Hence, a scientist can contribute to the formation of a theory by conducting an experiment with replicability in order to test a hypothesis.</u>
Huge masses of rock rise from deep inside Earth, travel along its surface and then sink back down. The process is known as plate tectonics. We rarely see those changes as they happen. Yet plate tectonics affects everyone.
