What Are 2 Forces That Can Expose Once Deeply Buried Fossils? The 2 forces are erosion and uplift that expose once deeply buried fossils. Why are most fossils found in sedimentary rocks? Almost all fossils are preserved in sedimentary rock. Organisms that live in topographically low places (such as lakes or ocean basins) have the
What Do Fossils Provide Evidence For? Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. … Fossils provide a snap shot of the past and allow us to study how much or how little organisms have
What Are The Uses Of Fossils? Fossils of any kind are useful in “reading the rock record,” meaning they help us decipher the history of the earth What are three ways fossils are useful? Fossils form in five ways: preservation of original remains, permineralization, molds and casts, replacement, and compression. Rock formations with exceptional fossils
What Can Be Said About Rock Layers That Contain The Same Index Fossils But Are Found In Different Areas Of The World? If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time. Thus, the principle of faunal succession makes it possible to determine
What Is A Solid Copy Of The Shape Of An Organism? A mold is a hollow area in rock in the shape of an organism or part of an organism. A mold forms when the hard part of an organism, such as a shell, is buried in sediment. … If the water deposits the minerals
What Are The Two Characteristics Of Index Fossils? A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time. Index fossils are the basis for defining boundaries in the geologic time scale How do you identify an index fossil? To be considered an
What Cannot Become A Fossil? For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the
What Characteristics Make An Organism A Good Index Fossil? A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time. Index fossils are the basis for defining boundaries in the geologic time scale Which fossil could be a good index fossil? Trilobites are
What Do You Mean By Fossil Fuels? Photograph by Hywit Dimyadi/Shutterstock. Encyclopedic Entry Vocabulary. Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth’s crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels. What defines fossil
What Can Fossils Tell Us About Past Environments? By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. How
