What can fossils tell us about the future?
Fossils can tell us the climate and change in the future....
Are fossils an example of a physical or chemical change?
Fossils are the results of the degradation of the organic material - chemical processes.
Did either animal change its speed how can you tell Fossils?

Scientists use a what to determine if a transformation was successful?
Scientists use a genetic marker to determine the success of a transformation. Genetic markers will change if the transformation has succeeded.

Which of the following fossil discoveries best demonstrates a change in the Earth's climate?
Scientists find a large amount of fossils of tropical plants and animals in a desert.
How the fossils record supports the theory of punctuated equilibrium?
the fossils show massive change at one time (for instance the Grand Canyon; this massive change occurs usually from significant weather/environmental events) , and during the periods between the significant changes not much evolution (changes in genetic expression/genes) occurs.
What is environmental change?
Environmental change is when the environment goes under changes such as climate which animals have to adapt to.

How can scientists use the fossil record to provide evidence that evolution of organisms has occurred over time?
Using methods such as radioactive dating, scientists can determine the approximate age of a fossil or the rock in which it was found. Utilizing this knowledge of approximate age, scientists can compare progressive fossils, and identify changes. Changes are often minimal, and sometimes organisms do not change at all for large amounts of time, making comparative analysis of fossils a tedious task. Some eras produced better fossils than others. This can have several causes, such as particularly prolific habitation of environments that more easily produce fossils, general population booms, certain mass extinction events, and even happenstance. Because some eras produce better or more fossils, and some produce few to almost none, the fossil record can sometimes falter. In such cases, scientific investigations may be forced to fill in blanks between species using genetic analysis of preceding and proceeding species or groups within species, if the fossil(s) contain(s) any remaining genetic material. In other cases, computers will be used to recreate images of the species based on fossils, and identify progression between species. In any case, the fossil record is often used as a base off of which to obtain or recreate further information about an organism's evolutionary history.
If species didn't change what type of fossils would we see?
If there was no change in species over time, then all fossils of that species would be identical.
Are fossils an example of a physical or chemical change?
Fossils are the results of the degradation of the organic material - chemical processes.
What is environmental elasticity?
Environmental elasticity is the responsiveness of demand for a product to a change in the environmental impact of the product.
How do fossils help geologists?
Fossils help geologists discover new species. Fossils also explain and show the age of the specimen and change in life forms.
