Existing landforms are modified by destructive forces, perhaps even eroded away by water, wind, ice, and gravity. Beneath the oceans, volcanic activity forms new seafloor while old seafloor is destroyed at the trenches.
Answer:
A <u> theory </u> may be formed from many related hypotheses that have been tested and support the evidence.
Explanation:
<u>A THEORY -:</u> A theory is a well-established, tested explanation that gives some part of the natural world a unified description. A hypothesis is focused on substantiated knowledge, repeated testing, and a large community of scientists / researchers agree on it.
The aim of a theory is to try to understand phenomena that many researchers have examined extensively and carefully over time. A hypothesis does not prove that the "unified description is correct." However, because the theory is the result of scientifically based research, the theory (as opposed to a single hypothesis) is more likely to be correct. Any hypothesis can (and should) be tested, but many trained scientists must scientifically perform and study the experiments.
