Toricelli was not known for contributions about composition of matter.
Observations of Pluto's orbit and size did not provide enough evidence to change its status from a planet. Astronomers cited factors such as its small size and irregular orbit as reasons for excluding it from the planetary classification.
they could discover a new atom and it would change
Yes climate scientists think that people are affecting climate change mostly from carbon emissions (from burning fossil fuels) and because we have destroyed the forests of the world that used to absorb carbon dioxide from the atmosphere.
A change in community compositions because fires are natural disturbances that maintain the community structure
Yes, it is possible; for example complete or not complete burning.
If new observations do not fit exactly with the current theory.

observations change
Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.

observations change.
Scientists are most likely to change a scientific theory if new evidence contradicts the existing theory, if the theory fails to explain new observations accurately, or if a more comprehensive theory emerges that better explains the phenomena in question. Scientific theories are constantly refined and updated based on rigorous testing and evidence.
Yes climate scientists think that people are affecting climate change mostly from carbon emissions (from burning fossil fuels) and because we have destroyed the forests of the world that used to absorb carbon dioxide from the atmosphere.
Approximately 97 of scientists believe that climate change is real.
There has been more and more observations about the atom that has changed it since then. They revised it to explain the observations.
They relied more on evidence.
A theory can change through new evidence that contradicts or supports it, advancements in technology that allow for more accurate measurements or observations, or through improvements in scientific understanding. As scientists gather more data and knowledge, theories may be revised or replaced to better explain the natural world.
