Scientific evidence that can be quantified and measured over time is often best for determining changes over time. This includes measurements of physical properties such as temperature, pressure, and pH levels, as well as chemical analysis for changes in composition or molecular structure. Geologic evidence such as sedimentary layers and isotopic analysis can also provide valuable information about changes over time. Additionally, longitudinal studies that track the same variables or subjects over an extended period can provide insights into trends and patterns over time.
