Document Summary
Determines whether the question has an answer. Control variable: all variables except one independent variable. Dependent variable: what"s being measured changes during the experiment. Darwin lived in a time when scientific views were changing: biologists saying that species had changed over time, and geologists saying that the world is ancient and has changed over time. By finding fossils, darwin realized that species have changed over time. Hutton and lyell concluded that earth is really old and that the processes that changed earth in the past are the same ones that are changing earth now. Hutton and lyell: layers of rock were bent and folded by forces under earth"s surface sometimes to become mountains and valleys, earth"s natural forces then turned earth into how we see it now. Uniformitarianism- says that the laws of nature are constant so the laws of nature we see today are the same as in the past.
