What can scientists learn by studying fossils I. how the Earth's surface has changed over time II. the appearance of an organism and its structures III. how species have changed over time IV. how the?
By studying fossils, scientists can learn how species have changed over time (III), providing insights into evolution and extinction events. Fossils also reveal the appearance and structures of ancient organisms (II), which helps reconstruct past ecosystems. Additionally, they can indicate how the Earth's surface has changed over time (I), such as shifts in climate and geography, by showing where different organisms lived in relation to environmental conditions.
What can changes in the fossils of a single organism over time reveal?
how the species evolved
Fossils in which replace all or part an organism?
Fossils created when minerals gradually replace the organic material of an organism, preserving its shape and structure, are called petrified fossils or replacement fossils. Over time, the original material is dissolved, and minerals fill the space, creating a fossilized replica of the organism.
Where is evidence that organism have changed over time buried?
Evidence that organisms have changed over time is primarily buried in sedimentary rock layers, where fossils are found. These layers form as sediments accumulate over time, preserving the remains of ancient organisms. Additionally, fossils can be discovered in amber, ice, and other natural materials that can encapsulate and protect biological specimens for millions of years. This geological record provides crucial insight into the evolutionary history of life on Earth.
Can petrified fossils form when the minerals in water make a copy of the organism?
Yes, petrified fossils can form when the organic material of an organism is replaced by minerals from water over time. This process is called permineralization, where minerals fill in the pores and cavities of the organism's remains, creating a detailed replica of the original structure.
What animal fossil has changed very little over time?
The horse shoe crab changed very little over time. They are now known as living fossils.

What is fossils as evidence?
That animals have changed over time
What can changes in the fossils of a single organism over time reveal?
how the species evolved

What can a scientist learn from fossils?
They can learn about evolution, as many living fossils have changed quite a bit over time.
What is of how an organism has changed over time?
Evolution.
The fossil record is?
a record that shows how fossils have changed over time
What is history of how an organism has changed over time?
Evolution.
Why isn't uranium a fossil fuel?
It isn't from fossils, Oil and coal are from ancient fossils that changed into coal and oil over time
Why can you not find every type of organism that ever existed as a fossil?
because it is hard to solve the fossil and the organism it is
