Detailed explanation-1: -The fossil record provides evidence to support the theory of evolution. A scientific theory is a well-tested concept that explains a wide range of observations. Evolution is the gradual change in living things over long periods of time. The fossil record shows that millions of types of organisms have evolved.
Detailed explanation-2: -Fossils. Fossils provide solid evidence that organisms from the past are not the same as those found today, and fossils show a progression of evolution. Scientists determine the age of fossils and categorize them from all over the world to determine when the organisms lived relative to each other.
Detailed explanation-3: -Ice cores provide direct information about how greenhouse gas concentrations have changed in the past, and they also provide direct evidence that the climate can change abruptly under some circumstances.
Detailed explanation-4: -Index fossils, are fossils that are used to estimate the absolute age of the rock layers in which they are found. Once the absolute age of an index fossil is known, it can be used to determine the age of rock layers that contain the same index fossil anywhere on Earth.
